A transcriptional atlas of the silk gland in Antheraea pernyi revealed by IsoSeq
Duan Jianping,Li Shanshan,Zhang Zhengtian,Yao Lunguang,Yang Xinfeng,Ma Sanyuan,Duan Nini,Wang Jiazhen,Zhu Xuwei,Zhao Ping 한국응용곤충학회 2023 Journal of Asia-Pacific Entomology Vol.26 No.2
Silk fibers spun by the silk gland of Antheraea pernyi have many unique properties and are of great value in genetic improvement and non-traditional applications. However, the complete transcriptional landscape and accurate genic annotation of the silk gland are yet to be conducted, which limits related studies on this organ. In this study, isoform sequencing revealed the full-length transcriptome of the A. pernyi silk gland, producing 12,572 high-confidence isoforms from 7,658 genes, among which more than 40 % of genes have not yet been annotated in the reference genome. Moreover, approximately 9 % of isoforms are computationally identified as long non-coding RNAs (lncRNAs). Up to 1,492 alternative splicing (AS) and 3,068 alternative polyadenylation (APA) events were revealed within this transcriptome. In addition, 2,569 putative transcription factors (TFs) belonging to 68 different families were first identified in A. pernyi genome, including 871 TFs in silk gland, and some TF families have undergone expansion or contraction. This study significantly improve our knowledge of the genes expressed in the silk gland of A. pernyi and provide a valuable resource for the in-depth study of silk protein synthesis and spinning, genetic improvement, and non-traditional applications in A. pernyi.

Screening for MiRNAs Related to Laryngeal Squamous Carcinoma Stem Cell Radiation
Huang, Chang-Xin,Zhu, Ying,Duan, Guang-Liang,Yao, Ji-Fen,Li, Zhao-Yang,Li, Da,Wang, Qing-Qing Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.8
Objective: To use microarray chip technology for screening of stem cell radiation related miRNAs in laryngeal squamous cell carcinoma; study and explore the relationship of miRNAs with radiosensitivity of laryngeal squamous cells. Method: After conventional culture and amplification of the laryngeal squamous carcinoma cell line Hep-2, CD 133+ cells were screened out with combination of isolated culture of stem cell microspheres and FACS for preparation of laryngeal cancer stem cells. After radiation treatment, miRNAs of laryngeal squamous carcinoma stem cells before and after radiation were enriched and purified. After microarray hybridization with mammalian miRNA and scanning of fluorescence signal, the miRNAs of laryngeal squamous carcinoma stem cells before and after radiation was subject to differential screening and clustering analysis. Real-time quantitative RT-PCR was used to verify part of the differentially expressed miRNAs. Results: 70 miRNAs related to laryngeal cancer stem cell radiation with 2-fold difference in expression were screened out, in which 62 were down-regulated and 8 were up-regulated. Fluorescent quantitative RT-PCR results were consistent with miRNAs chip results. Conclusion: Some miRNAs may be involved in self-regulation with laryngeal squamous carcinoma stem cell radiation.
