        본고는 <한국문집총간>을 대상으로 조선조 首尾吟體를 창작한 문인 현황을 파악하고 그 구체적인 작법을 확인하는 것을 목표로 한다. 수미음체는 첫 구와 마지막 구를 반복사용하는 것을 기본 원칙으로 하는 詩體의 일종으로 대개 雜體詩의 하나로 인식된다. 宋 邵雍(1011~1077)이 중국 문단에 이를 처음으로 선보인 뒤로 중국에서 뿐만 아니라 조선 문단에서도 적지않 은 문인들이 그의 시에 차운하거나 새로이 모방하였는데, 그 중 대표적인 인물로 尤庵 宋時烈 및 過齋 金正默 등 몇몇의 특정 인물이 거질의 연작시를 창작하였고, 그 외 私淑齋 姜希孟, 息山 李萬敷가 다수의 수미음체를 남 긴 사실을 확인하였다. 수미음체의 작법은 일률적이지 않았는데 기본형을 비롯해 창작양상에 있어 크게 세 가지로 구분할 수 있다. 첫째, 소옹이 그러했듯 첫 구와 마지막 구를 동일하게 처리하는 경우로써 대부분의 작품이이 방식을 준수하였다. 여기에는 소옹의 수미음체에서 구사한 싯구 일부를 그대로 차용하는가하 면, 작가 임의로 새로운 싯구를 중복 처리한 경우가 있다. 둘째, 매편 首聯 첫 구와 尾聯 첫 구에 각각 동일한 싯구를 삽입하는 경우로써 두 편 이상의 작품을 지을 때라야 구사 가능한 방식이 그것이다. 세 번째, 첫 구 첫 단어와 마지막 구 마지막 단어를 동일하게 처리함으로써 首尾一貫의 형식을 약식 으로 처리하였는데, 이 경우 ‘君恩'을 삽입하였다. 수미음체는 처음과 마지막 구의 반복을 통해 시인이 전달하고자 하는 의미를 강조하고 이에 따른 운율을 형성하였으며, 주제 강화 및 시적 정서의 완결성을 기하여 작품의 구조적 완결성을 확보하였다. 이러한 작법은 근・현 대로 이어져 首尾相關, 首尾雙關, 首尾相應이라는 작법의 하나로 계승되어, 예컨대 김소월(1902~1934)의 <엄마야 누나야>・<진달래꽃>・<산유 화>, 유치환(1908~1967)의 <울릉도>, 조지훈(1920~1968)의 <승무>, 신동엽(1930~1969)의 <산에 언덕에> 등의 작품에서 수미상관의 기법이 준용되었다. 이렇듯 宋代 邵雍에 의해 시작된 이래 오랜 세월 문인들의 작시에 종종 활용되었던 수미음체는 조선조에 수용되어 현대에까지 계승되었으 니, 조선조 수미음체 창작과 현대시의 수미상관(수미상응)의 작법의 연관성 을 고려하여 詩作法의 史的 발달과정을 탐구해보는 것은 의미있는 작업이 되리라 생각한다. This study aims to identify the current status of literary writers who had created Su-Mi-Eum-Che in Joseon Dynasty through <Korean Literary Collections> and find their specific writing techniques. Su-Mi-Eum-Che is a kind of poetry whose basic principle is to repeat the first line and the last line and typically recognized as one of the Jap-Che poetries. Since Song So-Ong(1011~1077) introduced this to the Chinese literary world, not a few literary writers borrowed or imitated such a line to their own poetry in Joseon as well as in China. The representative figures are Uam Song Si-Yeol, Gwajae Kim Jung-Muk and some others who created serial poetries and additionally Sasukjae Gang Hee-Maeng and Siksan Lee Man-Bu who left multiple works of Su-Mi-Eum-Che.The writing techniques of Su-Mi-Eum-Che were not uniform and can be classified into three categories including basic form in terms of creative writing aspects. The first category is the case that the first line and the last line were treated in the same way as So-Ong did. Most of the works followed this category. Sometimes, some of the lines described in So-Ong's Su-Mi-Eum-Che were borrowed as they were, but other times, new lines were overlapped on writer's own discretion. Second, this category is the case that the same line was inserted into the first line of the first stanza (1stand 2nd line in a style of Chinese verse) and the last line of the last stanza (7th and 8th line in a style of Chinese verse) for every poem. This is available only if more than two works are created. Third, this category is the case that the first word of the first line and the last word of the last line were treated in the same way: the form of Su-Mi-Il-Gwan(consistent beginning and end). In this case, the word ‘royal benevolence (favor of lord)' was inserted. Su-Mi-Eum-Che emphasized the meaning that a poet aimed to convey through the repetition of the first and the last line and accordingly formed a rhythm and reinforced subject and raised completion of poetic feeling to obtain structural completion of works. This writing technique was succeeded to one of these writing techniques: Su-Mi-Sang-Gwan, Su-Mi-Ssang-Gwan, and Su-Mi-Sang-Eung in modern times. For example, Su-Mi-Sang-Gwan techniques were applied into Kim So-Wol(1902~1934)'s <HEY MOM HEY SIS>・<Azalea>・<Wild Flowers>, Yu Chi-Hwan (1908~1967)'s <Ulleungdo>, Jo Ji-Hun(1920~1968)'s <Dance in Buddhist Attire>, and Shin Dong-Yeop(1930~1969)'s <In the Mountaisn and Hills>. Like this, the Su-Mi-Eum-Che that had often been used in literary writers' poems for long years since its beginning by So-Ong in Song period was accepted in Joseon period and succeeded to this modern times. Therefore, it seems to become a significant work to explore the historical development process of poetics by taking into account of the association between the creation of Su-Mi-Eum-Che in Joseon period and the writing technique of Su-Mi-Sang-Gwan(Su-Mi-Sang-Eung) in modern poems.

        Serial values for hematologic and biochemical analysis after myocardial infarction in rats

        ( Mi Jin Lee ), ( Hyun Jin Tae ), ( Ying Hua Li ), ( Do Hyeon Yu ), ( In Ae Han ), ( Seok Won Lee ), ( Dong Choon Ahn ), ( In Shik Kim ), ( Jin Ho Park ) 한국가축위생학회 2008 韓國家畜衛生學會誌 Vol.31 No.2

        To diagnose acute myocardial infarction(MI), many cardiac markers have been used in hematologic and biochemical analysis, and many studies have been published for hema-tologic and biochemical analysis associated with human acute MI. However, after occurrence of acute MI, the serial investigation for values in hematologic and bioche-mical analysis including chronic MI has rarely been performed. To observe the change of the serial values in hematologic and biochemical analysis, we induced artificial MI. The left main descending artery(LMDA) of the left coronary artery was ligated during the progression(day 1, 3, 5, 7, 14 and 30) of MI. Total 66 Sprague-Dawley rats were divided into the sham group(n=24, thoracotomy without LMDA ligation) and the experimental(MI) group(n=42, with LMDA ligation). And all individual in each group was sacrified at day 1, 3, 5, 7, 14 and 30 for the hematologic and biochemical analysis. In comparison of hematologic analysis between the sham and MI groups, the mean values of red blood cell(RBCs), hemoglobin and hematocrit(HCT) showed a steady increase. In biochemical analysis, the mean values of glucose, choles-terol, total creatine kinase(CK) and isoenzyme MB, and lactate dehydrogenase(LDH) were increased in all MI groups compared with the sham groups. The results of this study suggest that early hematologic and biochemical mean values occurred after acute MI are similar to those of human acute MI. In conclusion, we could observe the alterations and serial values in hematologic and biochemical analysis to the extent of chronic status after acute MI.

        심근경색 모델 흰쥐에서 스트레스가 B-type Natriuretic Peptide 발현 및 심박변이율 변화에 미치는 영향

        이삼윤(Sam Youn Lee), 이미경(Mi Kyoung Lee), 김남호(Nam-ho Kim), 주민철(Min Cheol Joo), 조항정(Hyang Jeong Jo), 강지숙(Ji Sook Kang), 김병숙(Byung Sook Kim), 윤선식(Sun Sik Yoon), 최을식(Eul Sig Choi), 이문영(Moon Young Lee) 대한스트레스학회 2010 스트레스硏究 Vol.18 No.3

        심박변이율의 감소는 심근 경색 환자에서 예후의 악화와 관련되어 있다. 심박변이율 중 very low frequency가 심부전환자의 예후를 판단할 수 있는 독립적 인자로서 사용이 가능하다고 보고된 바 있으며, 심실의 압력 증가에 반응해서 생성되는 B-type natriuretic peptide가 심근 경색의 예후 인자로서 사용할 수 있음 역시 보고된 바 있다. 본 연구에서는 심근경색 모델을 제작하여 일정의 회복 기간을 거친 다음 다시 일정 기간의 스트레스를 겪게 한 후 심박변이율의 변화 및 심실 조직에서의 BNP 발현 정도를 비교하여 스트레스에 의한 영향을 관찰하고자 하였다. Sprague-Dawley계 수컷 흰쥐 15마리를 대상으로 하였다. 실험동물은 인위적 스트레스 및 수술을 받지 않은 대조군(CON, n=5), 심근경색 수술을 받은 후 restraint stress를 받지 않은 군(MI+No Stress, n=5), 심근경색 수술을 받은 후 1주일 동안 restraint stress를 받은 군(MI+Stress, n=5)으로 분류하였다. 심근경색 모델 제작 직후 15분 이상 심전도의 변화를 기록하였으며, 2개월 정도 후 심근경색 수술을 받은 동물을 두 군으로 나누어 그 중 한 군에는 1주일 동안 restraint stress를 가한 후 restraint stress를 가하지 않은 동물과 심박변이율을 비교 분석하였다. 심실 조직은 좌심실 전벽 부위의 위축을 관찰할 수 있었고, 대식세포에 의하여 응고, 괴사된 심근세포의 탐식과 혈관이 풍부한 육아조직 및 섬유 변화를 볼 수 있었다. 심박변이율은 심근경색 수술을 받은 직후 심박수는 유의한 증가를 보였고, standard deviation of the normal to normal intervals (SDNN), very low frequency (VLF) 및 low frequency (LF)의 유의한 감소를 보였다. 심근경색 수술을 받았던 동물에서 두 달 정도의 회복 기간을 거친 후 스트레스를 받지 않은 군은 심박수 및 기타 심박변이율 분석에서 SDNN 값을 제외하고는 정상군과 유의한 차이를 관찰할 수 없었던 반면 1주일 동안 스트레스를 받은 군에서는 심박수가 다시 유의하게 증가했을 뿐만 아니라 SDNN, VLF 및 LF 역시 정상군과 유의한 차이를 보였다. 이상의 결과를 종합하면 심근경색 동물에 대해 1주일 동안 스트레스를 가한 결과 심박변이율이 감소하고 심실에서의 BNP 발현은 더욱 증가하여 악화함을 보여주고 있다. Diminished heart rate variability (HRV) is associated with less favorable prognosis after myocardial infarction (MI). It has been reported that very low frequency (VLF) power in HRV analysis is an independent risk predictor in patients with congestive heart failure and B-type natriuretic peptide (BNP) can be used as a prognostic factor of MI. The purpose of this study was to investigate whether stress has an effect to the changes of BNP expression and/or heart rate variability in MI model in rats. Male Sprague-Dawley rats were divided into 3 groups: control group (CON), MI group (MI+No Stress), and MI followed by stress group (MI+Stress). MI+Stress group rats were raised for a two month recovery period after the operation, followed by being exposed to restraint stress for 2 hours per day for 1 week. Electrocardiogram was recorded after the operation and the last day after 1 week of stress. The frequency components of HRV were calculated in the frequency domain such as VLF, low frequency (LF), high frequency (HF) and so on. In HRV analysis, standard deviation of the normal to normal intervals (SDNN) was significantly reduced in both groups compared to the control group. VLF and LF also were significantly reduced in MI+Stress group compared to the control groups. In addition, BNP expression in western blotting was shown the strongest bands in MI+ Stress group among experimental groups. These results suggest that BNP and HRV were aggravated by stress in MI rat model. (Korean J Str Res 2010;18:275∼285)

        Alterations of Proteins in Artificially Induced Chronic Myocardial Infarction in Rats

        Mi-Jin,Lee,Hyun-Jin,Tae,Do-Hyeon,Yu,Ying-Hua,Li,Jong-Hyun,Lee,Ji-Seon,Yoon,Seok-Won,Lee,In-Shik,Kim,Jin-Ho,Park 한국임상수의학회 2008 한국임상수의학회지 Vol.25 No.3

        We investigated the changes of protein in chronic MI which was occurred with long-term ischemia, without reperfusion. Sprague Dawley (SD) rats were divided into the sham group and the experimental groups (MI groups). The sham group was treated only thoracotomy without ligation for left main descending artery (LMDA) of left coronary artery (LCA), and the experimental groups (MI7d, ligation of LMDA for 7 days and MI30d, ligation of LMDA for 30 days) were conducted an artificial chronic MI. The change of proteins according to passage of times was compared and analyzed on first and second dimension (1 and 2D) sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) analysis. Among total 46 spots expressed differentially in the sham group versus MI7d and MI30d groups on 2D gel, we selected proteins that the volume of spot was increased in the MI7d and MI30d groups compared with the sham group. After that, the proteins were identified through liquid chromatography/tandem mass spectrometry (LC-MS/MS) analysis. In result, we could obtain many proteins as follows; albumin, glucose regulated protein 58 KDa, similar to tripartite motif protein 50, ubiquinol-cytochrome c reductase core protein Ⅱ, sarcomeric mitochondrial creatine kinase, ATP synthetase alpha chain (mitochondrial precursor) and creatine kinase. In conclusion, we suggest many changed proteins shown at chronic ischemia after artificial MI and consider that these proteins play an important role in the function of heart after MI.

        일반논문 : 정정렬제 최승희<춘향가> "광한루 풍경" 대목의 음군(音群)과 사설 및 시김새의 상호관계에 관한 연구 - 김소희 <춘향가> "적성가" 대목과의 비교 분석을 중심으로-

        유선미 ( Sun Mi You ) 판소리학회 2011 판소리연구 Vol.0 No.31

        판소리는 문학적인 사설과 음악적인 소리가 만나서 이루어진 우리나라 고유의 음악장르이다. 문학인 사설을 지어내려면 어떤 이야기를 지을 것인지 생각하고, 그에 맞는 주제를 찾고, 그 주제를 어떻게 풀어갈 것인지 전개방식을 선택하여 이야기를 엮어가는 것이다. 그리하여 하나하나의 단락들이 만들어지고 이어나가면서 커다란 사설이 완성되어 지는 것이다. 음악적인 소리는 주어진 사설에 음을 사용하며 선율을 만들어 나간다. 판소리에서 주어진 사설에 무슨 음을 사용하여 어떻게 엮어 음악을 만들어 가는 것인지를 살펴보는 것은 중요한 연구 과제라 생각한다. 따라서 본 연구는 판소리의 최소한의 선율을 이루는 음군과 사설 및 시김새의 상호관계를 분석하여 판소리 악보의 독창성과 즉흥성의 핵심요인을 분석하는데 목적이 있다. 본고에서는 오용록이 제시한 동적(動的)음계론의 ``음군(音群)``이라는 개념을 적용하여 정정렬제 최승희<춘향가>中 ``광한루 풍경`` 대목의 한 단락에서 사용되는 ``음군(音群)``을 분석해 보았다. 더불어 이 음군들과 판소리 사설과의 상관관계, 그리고 음군과 시김새의 상관관계를 고찰하여 본 결과 다음과 같은 결론에 도달했다, 첫째, 정정렬제 최승희의 ``광한루 풍경``은 사설의 내용이 동편·북편·서편·남편의 방향 풍경을 나열하여 설명한 것으로 사설 내용은 4단락으로 구분지어 볼 수 있으나 선율음으로 보면 3단락으로 나누어진다. 제1단락(제1~5각)의 음군은 미-솔(도섭선율), 미-레, 미-솔, 레-솔이고, 제2단락(제6~8각)의 음군은 미-솔(도섭선율), 미-도이며, 제3단락(제9~14각)의 음군은 미-솔(도섭선율), 미-솔-레, 레-도, 미-라, 미-레(당겨 붙인 선율), 미-도, 도-솔(1장 종지선율)이다. 둘째, 음군은 장단의 각과는 상관없고 사설의 구절에 따라 2음이나 3음이 붙는다. 다시 말하면 사설의 1음보에 음군 하나가 붙어 최소 선율 골격을 이루고 여기에 가변음이 붙어 소리선율을 엮어간다. 음군과 가변음으로 엮어진 소리 선율음의 앞이나 뒤에 붙어서 덩어리를 이루는 시김새는 창자가 사설의 어감이나 음악적 느낌을 가락이나 표현기교로 나타내는 것이다. 이상과 같이 판소리의 음군은 사설과 밀접한 관계를 갖고 있으며 시김새 붙임에 따라 다른 창자와는 구별되는 모습을 갖게 된다. 따라서 판소리에서 음악 이야기를 엮어가는 최소선율 음군과 시김새 음군을 이해함으로써 남이 따라갈 수 없는 그 사람만의 특징을 지니는 독창적인 소리의 멋을 표현할 수 있을 것이다. Pansori is the unique genre of Korean traditional music, composed of literary lyrics and musical melodies. Composing this literary lyrics includes how to design the story, find its theme, and develop it. From these processes, as one paragraph is connected with the next paragraph. one story of Pansori can be completed. The melodies related in these lyrics are created using musical notes. Thus it is important to examine what are the notes used in the melodies and how these sounds are composed for the story. Therefore, this study aims to analyze ``Eumgun``, the minimum unit of the melodies, Sigimsae and the lyrics of Pansori. This study analyzed ``Eumgun``, the tonal group used in one paragraph of ``Kwanghan-nu scenery`` part in the Pansori <Chunhyangga> of Choi, Seung Hee Jeong, Jeong Ryeol je quoting ``Eumgun``, ``tonal group`` of dynamic scale theory called by Oh, Yong Nok. In addition, this paper focused on the interrelation between ``Eumgun``, and the lyrics, and Sigimsae of the Pansori. The followings are resulted from this study. ■ ``Kwanghan-nu scenery`` of Choi, Seung Hee Jeong, Jeong Ryeol je is composed of three Eumgun of the first <mi, sol / mi-re, mi-sol, re-sol>, the second <mi-sol, mi-do>, the third, <mi-sol, mi-sol-re, re-do, mi-la, mi-re, mi-do, do-sol> around mi as compared with the lyrics that mean the east side·the north side·the west side·the south side of Kwanghan-nu scenery. ■ The Eumgun of Pansori is constructed by 2 or 3 notes according to the passage of its lyrics regardless of the gak of Jangdan. As one Eumgun is attached to one passage of the lyrics, it comprises the minimum melody unit, and additional notes develop it. These Eumgun and additional notes organize the melody lines of the lyrics and then Sigimsae is added around them. Sigimsae is used to express the connotation of the lyrics and feel of the singer. Although Choi, Seung Hee and Kim, So Hee use same tonal group in this Pansori, they have different musical form because of using different Sigimsae. Consequently, Eumgun in Pansori is closely related with its lyrics. Although same Eumgun is used, the characteristics of singers can be distinguished according to using different Sigimsae. This paper verified that through using the different Eumgun and Sigimsae in pansori, the creativities of singers can be examined and understood.

      • Transcriptional activation of hypoxia-inducible factor-1α by HDAC4 and HDAC5 involves differential recruitment of p300 and FIH-1

        Seo,,Hee-Won,Kim,,Eun-Jin,Na,,Hyelin,Lee,,Mi-Ock Elsevier 2009 FEBS letters Vol.583 No.1

        <P><B>Abstract</B></P><P>The interplay between hypoxia-inducible factor-1α (HIF-1α) and histone deacetylase (HDACs) have been well studied; however, the mechanism of cross-talk is unclear. Here, we investigated the roles of HDAC4 and HDAC5 in the regulation of HIF-1α function and its associated mechanisms. HDAC4 and HDAC5 enhanced transactivation by HIF-1α without stabilizing HIF-1α. HDAC4 and HDAC5 physically associated with HIF-1α through the inhibitory domain (ID) that is the binding site for factor inhibiting HIF-1 (FIH-1). In the presence of these HDACs, binding of HIF-1α to FIH-1 decreased, whereas binding to p300 increased. These results indicate that HDAC4 and HDAC5 increase the transactivation function of HIF-1α by promoting dissociation of HIF-1α from FIH-1 and association with p300.</P><P><B>Structured summary:</B></P><P>MINT-6802187:</P><P><I>HIF1 alpha</I> (uniprotkb:Q16665) <I>physically interacts</I> (MI:0218) with <I>FIH1</I> (uniprotkb:Q9NWT6) by <I>anti bait coimmunoprecipitation</I> (MI:0006)</P><P>MINT-6802058:</P><P><I>HIF1 alpha</I> (uniprotkb:Q16665) <I>physically interacts</I> (MI:0218) with <I>HDAC4</I> (uniprotkb:P56524) by <I>pull down</I> (MI:0096)</P><P>MINT-6802021:</P><P><I>HIF1 alpha</I> (uniprotkb:Q61221) <I>physically interacts</I> (MI:0218) with <I>HDAC4</I> (uniprotkb:P56524) by <I>anti bait coimmunoprecipitation</I> (MI:0006)</P><P>MINT-6802036:</P><P><I>HIF1 alpha</I> (uniprotkb:Q61221) <I>physically interacts</I> (MI:0218) with <I>HDAC5</I> (uniprotkb:Q9UQL6) by <I>anti bait coimmunoprecipitation</I> (MI:0006)</P><P>MINT-6802102:</P><P><I>HIF1 alpha</I> (uniprotkb:Q16665) <I>physically interacts</I> (MI:0218) with <I>HDAC5</I> (uniprotkb:Q9UQL6) by <I>pull down</I> (MI:0096)</P><P>MINT-6802121, MINT-6802156:</P><P><I>P300</I> (uniprotkb:Q09472) <I>physically interacts</I> (MI:0218) with <I>HIF1 alpha</I> (uniprotkb:Q16665) by <I>anti bait coimmunoprecipitation</I> (MI:0006)</P>

        Effects of sperm insemination on the final meiotic maturation of mouse oocytes arrested at metaphase I after in vitro maturation

        Yoon,,Jeong,Juhn,,Kyoung-Mi,Yoon,,San-Hyun,Ko,,Yong,Lim,,Jin-Ho The Korean Society for Reproductive Medicine 2017 Clinical and Experimental Reproductive Medicine Vol.44 No.1

        Objective: The aims of this study were to investigate whether fertilization could induce the resumption of meiosis in mouse oocytes arrested at metaphase I (MI) after in vitro maturation (IVM), and to investigate the effect of $Ca^{2+}$ chelator treatment at the time of fertilization on the transition from MI to metaphase II (MII). Methods: MII-stage and arrested MI-stage mouse oocytes after IVM were fertilized, and then embryonic development was monitored. Blastocysts from each group were transferred into 2.5 days post-coitum pseudo-pregnant ICR mice. MI oocytes after IVM were treated with a $Ca^{2+}$ chelator to investigate the effect of $Ca^{2+}$ oscillations on their maturation. Results: As insemination time increased, the number of oocytes in the MI group that reached the MII stage also increased. The blastocyst rates and total cell numbers in the MII group were significantly higher than in the MI group. No pregnancy occurred in the MI group, but 10 pregnancies were achieved (10 of 12) in the MII group. The proportion of MI oocytes that matured to MII oocytes after fertilization was significantly higher in the non-treated group than in the $Ca^{2+}$ chelator-treated group. Conclusion: The findings that a higher proportion of MI-arrested oocytes progressed to MII after fertilization and that the MI-to-MII transition was blocked by $Ca^{2+}$ chelator treatments before fertilization indicate that the maturation of MI oocytes to MII oocytes is associated with intracellular $Ca^{2+}$ oscillations driven by fertilization.

      • Histone deacetylase 3 is selectively involved in L3MBTL2-mediated transcriptional repression

        Yoo,,Jung-Yoon,Choi,,Kyung-Chul,Kang,,HeeBum,Kim,,Young,Jun,Lee,,Jeongmin,Jun,,Woo,Jin,Kim,,Mi-Jeong,Lee,,Yoo-Hyun,Lee,,Ok-Hee,Yoon,,Ho-Geun Elsevier 2010 FEBS letters Vol.584 No.11

        <P><B>Abstract</B></P><P>This is the first report that L(3)mbt-like 2 (L3MBTL2) specifically interacts with the histone deacetylase domain of histone deacetylase 3 (HDAC3) via its MBT domain. Here, we show that L3MBTL2 selectively interacts with HDAC3, but not other class I HDACs. An in vitro peptide-binding assay demonstrated the specific association of HDAC3 with methylated histone-K20 tail and L3MBTL2. Furthermore, depletion of HDAC3 resulted in a decrease of methylated K20-H4, as well as an increase in acetylated histone H3. Consequently, HDAC3 knock-down selectively suppressed L3MBTL2-mediated transcriptional repression. Taken together, our results reveal the concerted action of both HDAC3 and L3MBTL2 in histone deacetylation and methylation-dependent transcriptional repression.</P><P><B>Structured summary</B></P><P>MINT-7719975: <I>L3MBTL2</I> (uniprotkb:Q969R5) and <I>HDAC3</I> (uniprotkb:O15379) <I>colocalize</I> (MI:0403) by <I>fluorescence microscopy</I> (MI:0416)</P><P>MINT-7719941, MINT-7719921: <I>L3MBTL2</I> (uniprotkb:Q969R5) <I>binds</I> (MI:0407) to <I>HDAC3</I> (uniprotkb:O15379) by <I>pull down</I> (MI:0096)</P><P>MINT-7719991: <I>HDAC3</I> (uniprotkb:O15379) <I>physically interacts</I> (MI:0915) with <I>L3MBTL2</I> (uniprotkb:Q969R5) by <I>anti bait coimmunoprecipitation</I> (MI:0006)</P><P>MINT-7719958: <I>L3MBTL2</I> (uniprotkb:Q969R5) <I>physically interacts</I> (MI:0915) with <I>HDAC3</I> (uniprotkb:O15379) by <I>anti tag coimmunoprecipitation</I> (MI:0007)</P><P>MINT-7719897: <I>HDAC3</I> (uniprotkb:O15379) <I>physically interacts</I> (MI:0915) with <I>L3MBTL2</I> (uniprotkb:Q969R5) by <I>two hybrid</I> (MI:0018)</P>
