Micropeptides: origins, identification, and potential role in metabolism-related diseases / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

With the development of modern sequencing techniques and bioinformatics, genomes that were once thought to be noncoding have been found to encode abundant functional micropeptides (miPs), a kind of small polypeptides. Although miPs are difficult to analyze and identify, a number of studies have begun to focus on them. More and more miPs have been revealed as essential for energy metabolism homeostasis, immune regulation, and tumor growth and development. Many reports have shown that miPs are especially essential for regulating glucose and lipid metabolism and regulating mitochondrial function. MiPs are also involved in the progression of related diseases. This paper reviews the sources and identification of miPs, as well as the functional significance of miPs for metabolism-related diseases, with the aim of revealing their potential clinical applications.

Injection of submandibular gland with recombinant Exendin-4 and adeno-associated virus for the treatment of diabetic rats / 中南大学学报(医学版)

OBJECTIVE@#To evaluate the therapeutic effects of recombinant Exendin-4 and double-stranded adeno-associated virus (Exendin-4/dsAAV) on SD rats with type 2 diabetes (T2DM) through injecting it into submandibular gland (SG).
@*METHODS@#The Exendin-4/dsAAV was injected into submandibular gland of diabetic rat. The insulin and α-amylase were detected by real-time PCR at the 2nd, 4th and 8th weeks. The immunohistochemisty was used to detect the insulin contents in SG at the 8th week. The concentration of blood glucose and levels of insulin secretion were detected after pancreatectomy.
@*RESULTS@#The SG gland was bigger in Exendin-4/dsAAV group than that in the control group, but the changes in α-amylase were not significant. The Exendin-4 and insulin gene expression was increased in the Exendin-4/dsAAV group (P<0.05). The Exendin-4 and insulin were positive in the SG. The blood glucose was lower and insulin concentration was higher in the Exendin-4/dsAAV group than those in the control group after pancreatectomy (P<0.05), and the insulin content was also increased in the dsAAV groups.
@*CONCLUSION@#Continuous expression of Exendin-4 in SG may improve glucose control and insulin secretion in T2DM rats through inducing expression of insulin.
