UDP-glucuronosyltransferase (UGT) genes,which belong to an ancient gene family and play very important roles in all organisms, encode extracellularly secreted proteins that are involved in the transfer of glycosyl residues fromactivated nucleotide sugars to acceptor hydrophobicmolecules (aglycones). Athetis lepigone is an important polyphagous pest worldwide, and since 2011 it has become one of the major maize pests in North China. However, there have been no studies on pesticides for the effective control of this pest. In this study,we identified 23 putative UGT genes in A. lepigone by analysing previous antennal transcriptomic data. Phylogenetic analysis showed that all of the AlUGTs are distributed within 11 of 14 insect UGT sub-families. Tissue expression analysis revealed that N70% of AlUGTs were primarily expressed in adult antennae, of which three (AlUGT33AD1, AlUGT40F6 and AlUGT40L4) and four (AlUGT33B18, AlUGT33F10, AlUGT40Q3 and AlUGT41D3) displayed male-biased and female-biased expression, respectively. SomeAlUGTs, however, had higher expression levels in non-antennal tissues. Our study is the first to identify UGT genes in A. lepigone,which will help us to elucidate the diverse functions of these genes, and ultimately provide potential targets that will facilitate the development of efficient and environmentally friendly pesticides against A. lepigone.

Zhang, Ya-Li,Sun, Feng-Ting,Zhang, Ze,Chen, Xiao-Xu,Liu, Ai-Xiang,Pan, Jing-Jing,Peng, Fei,Zhou, Shuai,Sun, Li-Jun Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.23

Forkhead-box (FOX) transcription factors comprise a large gene family that contains more than 50 members in man. Extensive studies have revealed that they not only have functions in control of growth and development, but also play important roles in different diseases, especially in cancer. However, biological functions for most of the members in the FOX family remain unknown. In the present study, the expression of 39 FOX genes in 48 kinds of cancer was mined from the Gene Expression Atlas database of European Bioinformatics Institute. The analysis results showed that some FOX genes demonstrate overlapping expression in various cancers, which suggests particular biological functions. The pleiotropic features of the FOX genes make them excellent candidates in efforts aimed to give medical treatment for cancers at the genetic level. The results also indicated that different FOX genes may have the synergy or antagonistics effects in the same cancers. The study provides clues for further functional analysis of FOX genes, especially for the pleiotropic biological functions and crosstalk of FOX genes in human cancers.

Background: The accessory tendon of the extensor hallucis longus (ATEHL) muscle is a common abnormal structure, and its clinical significance remains debatable. In this study, we provide the incidence of the ATEHL and characterize its morphological types in Asian cadavers and investigate its clinical applications. Methods: The tendons from 50 adult cadaveric feet, fixed in 10% formalin, were analyzed. We measured the length and width of both the ATEHL and the extensor hallucis brevis (EHB). Results: All dissected specimens had an ATEHL. The first metatarsophalangeal joint was surrounded by an accessory tendon that inserted onto the joint capsule and the dorsal base of the proximal phalanx. We classified the ATEHL into 3 types based on their directions. Differences in ATEHL type based on sex were not statistically significant. Conclusions: We found an ATEHL in all cadaveric specimens in this study. We surmise that the ATEHL acts as an antagonist with the EHB when the toe is extending, which might help prevent the occurrence of hallux valgus deformity.

Aims: Late recurrence (> 2 years) after liver resection of hepatocellular carcinoma (HCC) is usually considered as multi-centric tumors or de novo cancer formation. We aimed to investigate risk factors, patterns and outcomes of late recurrence after HCC resection. Methods: From a multicenter database from 2001 to 2015, 734 patients who were alive and recurrence-free at 2 years after curative resection of initial HCC were enrolled into this retrospective study. Univariate and multivariate Cox-regression analysis were used to identify independent risk factors of late recurrence. Patterns, treatments and outcomes of late recurrence were investigated and analyzed. Results: During a median follow-up of 78.0 months after surgery, 303 patients (41.3%) developed late recurrence. Multivariate analysis revealed that cirrhosis, macroscopic vascular invasion, satellites, and tumor size > 5cm were independent risk factors of late recurrence. Among them, 273 (90.1%) were sole intrahepatic recurrence, 30 (9.9%) were concurrent intrahepatic and extrahepatic recurrence, and none of them was sole extrahepatic recurrence; 165 (54.4%) patients received curative treatments for recurrent HCC, including re-resection, transplantation and local ablation. Multivariate analysis showed regular postoperative surveillance and receiving curative treatments were two independent protective factors of prolonging survival for those patients with late recurrence. Conclusions: Late recurrence is correlated with cirrhosis and certain tumor-related characteristics of initial HCC. The patterns of late recurrence suggest that postoperative surveillance after 2 years of surgery could be adjusted and more targeted. Regular postoperative surveillance improves the probability to receive curative treatments again, yielding to better outcomes for patients with late recurrence.

Purpose: This study evaluated the value of contrast-enhanced ultrasonography (CEUS) in the ultrasound-guided microwave ablation (MWA) treatment of symptomatic focal uterine adenomyosis.Methods: This retrospective study was conducted between March 2020 and January 2023, enrolling 52 patients with symptomatic focal uterine adenomyosis who had undergone MWA. All patients were examined with CEUS before and after MWA. The non-perfused volume (NPV) was compared between CEUS and dynamic contrast-enhanced magnetic resonance imaging (DCEMRI) following ablation. Therapeutic efficacy and safety were evaluated at 3-, 6-, and 12-month follow-ups. Additionally, this study explored the correlations between pre-treatment CEUS features and a volume reduction ratio indicating sufficient ablation, defined as 50% or more at the 3-month follow-up.Results: No significant differences in NPV were noted between CEUS and DCE-MRI immediately after MWA and during follow-up (all P>0.05). At the 3-month follow-up, the median VRRs for the uterus and adenomyosis were 33.2% and 63.9%, respectively. Sufficient ablation was achieved in 69.2% (36/52) of adenomyosis cases, while partial ablation was observed in the remaining 30.8% (16/52). The identification of non-enhancing areas on pre-treatment CEUS was associated with sufficient ablation (P=0.016). At the 12-month follow-up, significant decreases were observed in both the uterine and adenomyosis volumes (all P<0.001). Dysmenorrhea and menorrhagia were significantly alleviated at 12 months, and no major complications were encountered.Conclusion: CEUS can be used to evaluate the ablation zone of focal adenomyosis that has been treated with MWA, similarly to DCE-MRI. The identification of non-enhancing areas on pretreatment CEUS indicates satisfactory treatment outcomes.

Identification, fine mapping and characterization of Rht-dp, a recessive wheat dwarfing (reduced height) gene derived from Triticum polonicum

Hou-Yang Kang,Li-Juan Lin,Zhi-Jian Song,Jing-Ya Yuan,Mei-Yu Zhong,Hai-Qin Zhang,Xing Fan,Li-Na Sha,Yi Wang,Li-Li Xu,Jian Zeng,Yong-Hong Zhou 한국유전학회 2012 Genes & Genomics Vol.34 No.5

Semi-dwarfism is an agronomically important trait in breeding for resistance to damage by wind and rain (lodging resistance)and for stable high yields. Dwarf Polish wheat (Triticum polonicum L., 2n = 4x = 28, AABB AS304) is a potential donor of dwarfing and other traits for common wheat improvement. A genetic analysis using an F2 population derived from a cross of AS304 and tall cultivar AS302 and derived F2:3 lines indicated that AS304 carries a recessive dwarfing gene, temporarily designated Rht-dp. Molecular markers and bulked segregant analysis were used to characterize and map the gene. Eight polymorphic SSR markers (Xwmc511, Xgwm495, Xgwm 113, Xgwm192, Xgpw7026, Xgpw3017, Xgpw1108 and Xgpw7521) on chromosome arm 4BS and two AFLP markers (M8/E5 and M4/E3) were mapped relative to the dwarfing locus. The closest linked markers, Xgpw3017 and M8/E5 at 0.5 and 3.5 cM, respectively, from Rht-dp will enable its marker assisted transfer to wheat breeding populations. Allelic tests indicated that Rht-dp was allelic to Rht-B1b; hence it may be an alternative allele at the Rht-B1 locus.

A large number of extracts from the medicinal plants growing in Vietnam were screened for their in vitro antitrypanosomal activity toward Trypanosoma brucei. Among them, eighty-seven extracts showed the significant antitrypanosomal activity. Especially, the extracts from Neocinnamomum delavayi, Mallotus cuneatus, and Mallotus api exhibited the highest inhibitory activity against T. brucei (IC50: 0.16, 0.49 and <0.05 μg/mL). Cephalotaxus mannii, Pittosporum floribundum, Cleistanthus aff. annamensis, Wendlangia tinctoria subsp. barbatus, Maesa parvifolia, Alpinia malaccensis, Glycosmis scandens, Mallotus yunnanensis, and Maesa sp also presented potent T. brucei inhibitory activity, with IC50 value ranging from 1.14 to 4.98 μg/mL. Based on these results of screening study, the extracts from N. delavayi, M. cuneatus, M. api, C. mannii, P. floribundum, C. aff. annamensis, W. tinctoria subsp. barbatus, M. parvifolia, A. malaccensis, G. scandens, M. yunnanensis, and Mallotus sp. might be the rich source of antitrypanosomal components. Therefore, further phytochemistry and pharmacological study of these medicinal plants should be researched and developed.

Xu, Xin-Fang,Gao, Yan,Xu, Shu-Ya,Liu, Huan,Xue, Xue,Zhang, Ying,Zhang, Hui,Liu, Meng-Nan,Xiong, Hui,Lin, Rui-Chao,Li, Xiang-Ri The Korean Society of Ginseng 2018 Journal of Ginseng Research Vol.42 No.3

Background: Temperature is an essential condition in red ginseng processing. The pharmacological activities of red ginseng under different steam temperatures are significantly different. Methods: In this study, an ultrahigh-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry was developed to distinguish the red ginseng products that were steamed at high and low temperatures. Multivariate statistical analyses such as principal component analysis and supervised orthogonal partial least squared discrimination analysis were used to determine the influential components of the different samples. Results: The results showed that different steamed red ginseng samples can be identified, and the characteristic components were 20-gluco-ginsenoside Rf, ginsenoside Re, ginsenoside Rg1, and malonyl-ginsenoside Rb1 in red ginseng steamed at low temperature. Meanwhile, the characteristic components in red ginseng steamed at high temperature were 20R-ginsenoside Rs3 and ginsenoside Rs4. Polar ginsenosides were abundant in red ginseng steamed at low temperature, whereas higher levels of less polar ginsenosides were detected in red ginseng steamed at high temperature. Conclusion: This study makes the first time that differences between red ginseng steamed under different temperatures and their ginsenosides transformation have been observed systematically at the chemistry level. The results suggested that the identified chemical markers can be used to illustrate the transformation of ginsenosides in red ginseng processing.

Li, Jian,Xu, Ya-Hong,Lu, Yi,Ma, Xiao-Ping,Chen, Ping,Luo, Shun-Wen,Jia, Zhi-Gang,Liu, Yang,Guo, Yu Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.9

Purpose: Prostate cancer caused by the abnormal disorderly growth of prostatic acinar cells is the most prevalent cancer of men in western countries. We aimed to screen out differentially expressed genes (DEGs) and explore small molecule drugs for prostate cancer. Materials and Methods: The GSE3824 gene expression profile of prostate cancer was downloaded from Gene Expression Omnibus database which including 21 normal samples and 18 prostate cancer cells. The DEGs were identified by Limma package in R language and gene ontology and pathway enrichment analyses were performed. In addition, potential regulatory microRNAs and the target sites of the transcription factors were screened out based on the molecular signature database. In addition, the DEGs were mapped to the connectivity map database to identify potential small molecule drugs. Results: A total of 6,588 genes were filtered as DEGs between normal and prostate cancer samples. Examples such as ITGB6, ITGB3, ITGAV and ITGA2 may induce prostate cancer through actions on the focal adhesion pathway. Furthermore, the transcription factor, SP1, and its target genes ARHGAP26 and USF1 were identified. The most significant microRNA, MIR-506, was screened and found to regulate genes including ITGB1 and ITGB3. Additionally, small molecules MS-275, 8-azaguanine and pyrvinium were discovered to have the potential to repair the disordered metabolic pathways, abd furthermore to remedy prostate cancer. Conclusions: The results of our analysis bear on the mechanism of prostate cancer and allow screening for small molecular drugs for this cancer. The findings have the potential for future use in the clinic for treatment of prostate cancer.

Ya-Ping Zhang,Run Zhang,Hua-Yuan Zhu,Li Wang,Yu-Jie Wu,Jin-Hua Liang,Wen-Yu Shi,Hong Liu,Wei Xu,Jian-Yong Li 대한암학회 2019 Cancer Research and Treatment Vol.51 No.1

Purpose Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is a rare subtype of non- Hodgkin lymphoma, and asparaginase-based regimens are the best first-line treatments. Data on the role of specific circulating lymphocyte subsets in the progression of ENKTL are limited. The aim of this study was to investigate the clinical correlation and distribution of circulating absolute CD4+ T-cell counts (ACD4Cs) in ENKTL. Materials and Methods We retrospectively searched medical records for 70 newly diagnosed ENKTL patients treated with pegaspargase-based regimens. Comparison of ACD4Cs as a continuous parameter in different groups was calculated. Univariate and multivariate analyses were used to assess prognostic factors for overall survival (OS) and progression-free survival (PFS). Results Stage III/IV, B symptoms, elevated lactate dehydrogenase, monocytopenia, high-intermediate and high risk International Prognostic Index (IPI) and Korean Prognostic Index (KPI), high risk Prognostic Index of Natural Killer Lymphoma (PINK), and lower lymphocytes were significantly associated with low ACD4C at diagnosis. With a median follow-up time of 32 months, patients who had an ACD4C < 0.30109/L had a worse OS. Median OS was 11 months and median PFS was 5 months in the low ACD4C cohort. There were significant differences in both OS and PFS between the two cohorts. Moreover, multivariate Cox analysis identified ACD4Cs as an independent predictor for OS and PFS. Conclusion Low ACD4Cs were associated with poorer survival and could act as a negative predictor for ENKTL patients treated with asparaginase-based regimens.
