Background/Aims: Hepatolithiasis or primary intrahepatic stones may be accompanied later by intrahepatic cholangiocarcinoma. This cancerous lesion is frequently associated with atypical hyperplastic epithelium that was suspected of being precancerous. To investigate the Ki-ras or p53 mutation may play a role in carcinogenesis, and to determine whether atypical hyperplastic epithelium may be precancerous, this study was performed in intrahepatic cholangiocarcinomas associated with hepatolithiasis. Methods: We examined 12 patients with intrahepatic cholangiocarcinomas associated with hepatolithiasis. Ki-ras point mutations were assessed by direct DNA sequencing. Expressions of p53 protein were immunohistochemically assessed. The overexpression of p53 and point mutation of Ki-ras were examined in normal, hyperplastic, atypical hyperplastic, and can- cerous tissues separately. Results: The expressions of p53 protein were detected in 4 (33%) of 12 cholangiocarcinomas and Ki-ras point mutations at codon 12 were found in 2 (17%) of 12 cholangiocarcinomas. In those two carcinoma cases which contained the mutant sequence of Ki-ras, the same point mutation from wild type GGT (glycine) to GAT (aspartic acid) was. found in the associated atypical hyperplastic epithelium. However, none of the normal and hyperplastic epithelium harbored Ki-ras or p53 mutations. Conclusions: The overexpression of p53 may play a part in the carcinogenesis of some intrahepatic cholangiocarcinomas associated with hepatolithiasis, whereas the role of Ki-ras mutations in those cases is dubious. However, Ki-ras point mutation at codon 12 may be responsible for either cancer or atypical hyperplastic epithelium associated with hepatolithiasis in certain cases, suggesting atypical hyperplastic epithelium may give rise to carcinoma.

Up to now only 17 coleopteran mitogenomes have been fully or near fully sequenced, but this chart does not include any complete mitogenome sequence of the coleopteran infraorder Scarabaeiformia, in which the monotypic Scarabaeoidea is included. In this study, we firstly present three scarabaeoid mitogenomes, two of which are completed and one is near completed. The complete nucleotide sequences of the white-spotted flower chafer, Protaetia brevitarsis (Scarabaeiformia: Scarabaeidae), was determined to be 20,319 bp, the two-spotted stag beetle, Metopodontus blanchardi (Scarabaeiformia: Lucanidae), was 21,678 bp, and the incomplete garden chafer, Polyphylla laticollis (Scarabaeiformia: Scarabaeidae), which lacks sequence information from whole A+T-rich region and a partial srRNA gene was 14,473 bp. Thus, the two complete mitogenome sequences are longest among the completely sequenced insect mitogenomes, followed by the 19,517 bp-long dipteran Drosophila melanogaster. Phylogenetic analysis using the concatenated 13 amino acid sequences of PCGs of the 13 coleopteran insects including three newly sequenced scarabaeoid successfully recovered a monophyly of suborder Polyphaga, a monophyly of infraorder Cucujiformia, a monophyly of infraorder Elateriformia, and also a monophyly of infraorder Scarabaeiformia within Polyphga. However, the Scarabaeiformia represented by three newly sequenced species was unexpectedly placed as a sister group to the Cucujiformia, instead of the placement to the sister to the Cucujiformia and Elateriformia group.

Phylogenetic Relationships of True Butterflies (Lepidoptera: Papilionoidea) Inferred from COI, 16S rRNA and EF-1${\alpha}$ Sequences

Kim, Man-Il,Wan, Xinlong,Kim, Min-Jee,Jeong, Heon-Cheon,Ahn, Neung-Ho,Kim, Ki-Gyoung,Han, Yeon-Soo,Kim, Ik-Soo Korean Society for Molecular and Cellular Biology 2010 Molecules and cells Vol.30 No.5

The molecular phylogenetic relationships among true butterfly families (superfamily Papilionoidea) have been a matter of substantial controversy; this debate has led to several competing hypotheses. Two of the most compelling of those hypotheses involve the relationships of (Nymphalidae + Lycaenidae) + (Pieridae + Papilionidae) and (((Nymphalidae + Lycaenidae) + Pieridae) + Papilionidae). In this study, approximately 3,500 nucleotide sequences from cytochrome oxidase subunit I (COI), 16S ribosomal RNA (16S rRNA), and elongation factor-1 alpha (EF-1${\alpha}$) were sequenced from 83 species belonging to four true butterfly families, along with those of three outgroup species belonging to three lepidopteran superfamilies. These sequences were subjected to phylogenetic reconstruction via Bayesian Inference (BI), Maximum Likelihood (ML), and Maximum Parsimony (MP) algorithms. The monophyletic Pieridae and monophyletic Papilionidae evidenced good recovery in all analyses, but in some analyses, the monophylies of the Lycaenidae and Nymphalidae were hampered by the inclusion of single species of the lycaenid subfamily Miletinae and the nymphalid subfamily Danainae. Excluding those singletons, all phylogenetic analyses among the four true butterfly families clearly identified the Nymphalidae as the sister to the Lycaenidae and identified this group as a sister to the Pieridae, with the Papilionidae identified as the most basal linage to the true butterfly, thus supporting the hypothesis: (Papilionidae + (Pieridae + (Nymphalidae + Lycaenidae))).

Mitochondrial DNA Sequence Variation of the Tiny Dragonfly, Nannophya pygmaea(Odonata: Libellulidae)

Kim, Ki-Gyoung,Jang, Sang-Kyun,Park, Dong-Woo,Hong, Mee-Yeon,Oh, Kyoung-Hee,Kim, Kee-Young,Hwang, Jae-Sam,Han, Yeon-Soo,Kim, Ik-Soo Korean Society of Sericultural Science 2007 International Journal of Industrial Entomology Vol.15 No.1

The tiny dragonfly, Nannophya pygmaea(Odonata: Libellulidae) is one the smallest dragonflies in the world and listed as a second-degree endangered wild animal and plant in Korea. For the long-term conservation of such endangered species, an investigation on nation-wide genetic magnitude and nature of genetic diversity is required as a part of conservation strategy. We, thus, sequenced a portion of mitochondrial COI gene, corresponding to "DNA Barcode" region(658 bp) from 68 N. pygmaea individuals collected over six habitats in Korea. The sequence data were used to investigate genetic diversity within populations and species, geographic variation within species, phylogeographic relationship among populations, and phylogenetic relationship among haplotypes. Phylogenetic analysis and uncorrected pairwise distance estimate showed overall low genetic diversity within species. Regionally, populations in southern localities such as Gangjin and Gokseong in Jeollanamdo Province showed somewhat higher genetic diversity estimates than those of remaining regions in Korean peninsula. Although geographic populations of N. pygmaea were subdivided into two groups, distance- or region-based geographic partition was not observed.

Description of Nearly Completed Mitochondrial Genome Sequences of the Garden Chafer Polyphylla laticollis manchurica, Endangered in Korea (Insecta: Coleoptera)

Kim, Min Jee,Kim, Ki-Gyoung,Kim, Iksoo Korean Society of Sericultural Science 2013 International Journal of Industrial Entomology Vol.27 No.1

In this study, we present the nearly complete mitogenome sequences of the garden chafer, Polyphylla laticollis manchurica, which is listed as an endangered species in Korea. The P. l. manchurica mitogenome, which includes unfinished whole A+T-rich region and a partial srRNA was 14,473-bp long, possessing typical sets of genes (13 PCGs, 22 tRNA genes, and 2 rRNA genes). Gene arrangement of the P. l. manchurica mitogenome was identical to the common one found in the majority of insects. The 5 bp-long motif sequence (TAGTA) that has been suggested to be the possible binding site for the transcription termination peptide for the major-strand was also found in the P. l. manchurica mitogenome between $tRNA^{Ser}$(UCN) and ND1. The start codon for COI gene and ATPase8 was designated as a typical TTG. All tRNAs of the P. l. manchurica showed a stable canonical clover-leaf structure of other mt tRNAs, except for $tRNA^{Ser}$(AGN), DHU arm of which could not form stable stemloop structure. As has been previously determined, the high A/T content was unanimously observed in P. l. manchurica in terms of A/T bias in the third codon position (73.5%) compared with the first (66.4%) and second codon position (66.2%). The PCGs encoded in major-strands are slightly T-skewed, whereas those of the minor-strand are A-skewed, indicating strand asymmetry in nucleotide composition in the Coleoptera including P. l. manchurica.

Complete Mitochondrial Genome Sequence of the Yellow-spotted Long-horned Beetle Psacothea hilaris (Coleoptera: Cerambycidae) and Phylogenetic Analysis among Coleopteran Insects

Ki Gyoung Kim,Mee Yeon Hong,Min Jee Kim,Man Il Kim,Chang Hwan Bae,Sook Jae Seo,Sang Hyun Lee,Iksoo Kim 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.05

We have determined the complete mitochondrial genome of the yellow-spotted long horned beetle, Psacothea hilaris (Coleoptera: Cerambycidae), an endangered insect species in Korea. The 15,856-bp long P. hilaris mitogenome harbors gene content typical of the animal mitogenome and a gene arrangement identical to the most common type found in insect mitogenomes. As with all other sequenced coleopteran species, the 5-bp long TAGTA motif was also detected in the intergenic space sequence located between tRNASer (UCN) and ND1 of P. hilaris. The 1,190-bp long non-coding A+T-rich region harbors an unusual series of seven identical repeat sequences of 57-bp in length and several stretches of sequences with the potential to form stem-and-loop structures. Furthermore, it contains one tRNAArg-like sequence and one tRNALys-likes equence. Phylogenetic analysis among available coleopteran mitogenomes using the concatenated amino acid sequences of PCGs appear to support the sister group relationship of the suborder Polyphaga to all remaining suborders, including Adephaga, Myxophaga, and Archostemata. Among the two available infraorders in Polyphaga, a monophyletic Cucujiformia was confirmed, with the placement of Cleroidea as the basal lineage for Cucujiformia. On the other hand, the infraorder Elateriformia was not identified as monophyletic, thereby indicating that Scirtoidea and Buprestoidea are the basal lineages for Cucujiformia and the remaining Elateriformia.
