Abhydrolase domain containing 16A (ABHD16A) is a member of the α/β hydrolase domain-containing (ABHD) protein family and is expressed in a variety of animal cells. Studies have shown that ABHD16A has acylglycerol lipase and phosphatidylserine lipase activities. Its gene location in the main histocompatibility complex (MHC) III gene cluster suggests that this protein may participate in the immunomodulation of the body. The results of studies investigating nearly 20 species of ABHDs reveal that the ABHD proteins are key factors in metabolic regulation and disease occurrence and development. In this paper, we summarize the related progress regarding the function of ABHD16A and other ABHD proteins. A prediction of the active sites and structural domains of ABHD16A and an analysis of the amino acid sites are included. Moreover, we analysed the amino acid sequences of the ABHD16A molecules in different species and provide an overview of the related functions and diseases associated with these proteins. The functions and diseases related to ABHD are systematically summarized and highlighted. Future research directions for studies investigating the functions and mechanisms of these proteins are also suggested. Further studies investigating the function of ABHD proteins may further confirm their positions as important determinants of lipid metabolism and related diseases.
Plants possess various natural antiviral properties. Epigallocatechin-3-gallate (EGCG), a major component of green tea, inhibits a variety of viruses. However, the clinical application of EGCG is currently hindered by a scarcity of information on its molecular mechanism of action. In the present study, we examined the anti-HBV (hepatitis B virus) effects of catechins from green tea at the transcriptional and antigen-expression levels, as well as the associated molecular mechanisms, because HBV-associated liver diseases have become a key public health issue due to their serious impact on human physical and mental health. By using fluorescence quenching and affinity binding, we demonstrated that EGCG is an important transcriptional regulator of the HBV genome, which it achieves by interacting with farnesoid X receptor alpha (FXRα). Luciferase assay showed that EGCG effectively inhibited the transcription of the HBV promoter dose-dependently when expression plasmids of FXRα and retinoid X receptor α (RXRα) were co-transfected into HEK293 cells. These results indicate that the downregulation of the HBV antigen and the decrease in the transcriptional activation of the HBV EnhII/core promoter by FXRα/RXRα are mainly due to the interaction between EGCG and FXRα. Therefore, EGCG, an antagonist of FXRα in liver cells, has the potential to be employed as an effective anti-HBV agent.
