Ubiquitin conjugating enzyme UbcM2 (Ubiquitin-conjugating enzymes from Mice, the number reveals the identification order) has been implicated in many critical processes, such like growth-inhibiting, mediating cell proliferation and regulation of some transcription factor, but the expression profile during mouse embryo development remains unclear. Hereby, during mid-later embryonic stage, the expression patterns of UbcM2 were examined using in situ hybridization and quantitative real-time PCR (qRT-PCR). The signals were significantly intense in central nervous system and skeletal system, weak in tongue, heart, lung, liver, and kidney. In the central nervous system, UbcM2 was principally expressed in thalamus, external germinal layer of cerebellum (EGL), mitral cell layer of olfactory bulb, hippocampus, marginal zone and ventricular zone of cerebral cortex, and spinal cord. In the skeletal system, UbcM2 was primarily expressed in proliferating cartilage. Furthermore, qRT-PCR analysis displayed that the expression of UbcM2 was ubiquitous at E15.5, most prominent in brain, weaker in lung liver and kidney, accompanied by the lowest level in tongue and heart. During brain development, the expression level of UbcM2 first ascended and then decreased from E12.5 to E18.5, the peak of which sustained starting at E14.5 until E16.5. Together, these results suggest that UbcM2 may play potential roles in the development of mouse diverse tissues and organs, particularly in the development of brain and skeleton.

  • Gene Expression The Journal of Liver Research will publish articles in all aspects of hepatology. Hepatology, as a research discipline, has seen unprecedented growth especially in the cellular and molecular mechanisms of hepatic health and disease, which continues to have a major impact on understanding liver development, stem cells, carcinogenesis, tissue engineering, injury, repair, regeneration, immunology, metabolism, fibrosis, and transplantation. Continued research and improved understanding in these areas will have a meaningful impact on liver disease prevention, diagnosis, and treatment. The existing journal Gene Expression has expanded its focus to become Gene Expression The Journal of Liver Research to meet this growing demand. In its revised and expanded scope, the journal will publish high-impact original articles, reviews, short but complete articles, and special articles (editorials, commentaries, opinions) on all aspects of hepatology, making it a unique and invaluable resource for readers interested in this field. The expanded team, led by an Editor-in-Chief who is uniquely qualified and a renowned expert, along with a dynamic and functional editorial board, is determined to make this a premier journal in the field of hepatology.
