The distribution of hepatitis C viral genotypes shifted among chronic hepatitis C patients in Yunnan, China, between 2008-2018.

Object: The hepatitis C virus (HCV) is prevalent across China, with a distinctive genotypic distribution that varies by geographical region and mode of transmission. Yunnan is one such geographical region wherein the local population continues to experience a high level of HCV infection, severely straining public health resources. This high prevalence is likely due to the increased incidence of intravenous drug use in that region, as Yunnan is a major point of entry for illegal heroin into China.

Single-cell data-driven mathematical model reveals possible molecular mechanisms of embryonic stem-cell differentiation.

Embryonic development is widely studied due to its application in disease treatment. The published literature demonstrated that Krüppel-like factor 8(KLF8) plays an important role in modulating mesendoderm to definitive endoderm (DE) differentiation. However, it is not clear how KLF8 interacts with other key genes and affects the differentiation process.

Identification and expression analysis of a doublesex1 gene in Daphnia pulex during different reproductive stages.

The gene doublesex (dsx) has shown deep conservation in the sex determination in many organisms. Environmental stimuli initiate a switch in the reproductive strategy of Daphnia pulex from asexual to sexual reproduction; however, occasionally, changes in environmental conditions will not lead to this transition. So study genetic responses to environmental stimuli and the molecular basis for the switch of reproductive stages are urgently needed.

SNP and mRNA expression for glutathione peroxidase 4 in Kashin-Beck disease.

Kashin-Beck disease (KBD) is a chronic endemic osteoarthropathy, which mainly occurs in West and Northeast China. Epidemiological studies suggest that Se deficiency is an important environmental factor for the incidence of KBD. Glutathione peroxidase 4 (GPx4) belongs to the glutathione peroxidase family, which is crucial for optimal antioxidant defences.
