Silencing of novel TtVtg6-like induced ovarian cell apoptosis in ancient chelicerate Tachypleus tridentatus
In this study, we have successfully elucidated the complete transcript sequence of TtVtg6-like from an ancient chelicerate Tachypleus tridentatus. The TtVtg6-like transcript encompassed a length of 4887 bp and encoded 1629 amino acids residues. Notably, TtVtg6-like was found to contain 25 exons. Furthermore, the molecular weight and isoelectric point of TtVtg6-like were determined to be 191.6 KDa and 6.73, respectively. Subsequent mRNA expression analysis demonstrated the specific expression of TtVtg6-like in ovary and yellow connective tissue. In addition, TtVtg6-like was located and distributed in both ovary and yellow c...

The Upregulation of miR-22 alleviates oxygen-glucose deprivation/reperfusion-induced injury by targeting Tiam1 in SH-SY5Y cells
In this study, we evaluated whether miR-22 participates in I/R-induced neuronal injury and the potential mechanism by using an oxygen-glucose deprivation/reperfusion (OGD/R) model in vitro. Our results showed that miR-22 was significantly down-regulated in SH-SY5Y cells suffering from OGD/R. Up-regulation of miR-22 by its specific mimic could protect SH-SY5Y cells against OGD/R-induced injury. The luciferase reporter assay demonstrated that T-cell lymphoma invasion and metastasis 1 (Tiam1) was a direct target of miR-22. MiR-22 mimic obviously inhibited Tiam1 expression in OGD/R-exposed SH-SY5Y cells. Tiam1 siRNA could atte...

Transcription Factor JunB Suppresses Hepatitis C Virus Replication
Kobe J Med Sci. 2023 Aug 31;69(3):E86-E95.ABSTRACTWe previously reported that hepatitis C virus (HCV) infection activates the reactive oxygen species (ROS)/c-Jun N-terminal kinase (JNK) signaling pathway. Activation of JNK contributes to the development of liver diseases, including metabolic disorders, steatosis, liver cirrhosis and hepatocellular carcinoma. JNK is known to have numerous target genes, including JunB, a member of activator protein-1 transcription factor family. However, the roles of JunB in the HCV life cycle and HCV-associated pathogenesis remain unclear. To clarify a physiological role of JunB in HCV infe...

MARCH8 downregulation modulates profibrotic responses including myofibroblast differentiation
In this study, we demonstrated decreased MARCH8 expression in IPF patients compared to non-PF controls and in bleomycin induced PF. TGF-β dose and time dependently decreased MARCH8 expression in normal and IPF human lung fibroblast (HLFs), along with induction of FMT markers α-SMA, collagen type I (Col-1), and fibronectin (FN). Interestingly, overexpression of MARCH8 significantly suppressed TGF-β-induced expression of α-SMA, Col-1, and FN. By contrast, knockdown of MARCH8 using siRNA upregulated basal expression of α-SMA/Col-1/FN. Moreover, MARCH8 knockdown enhanced TGF-β-induced FMT marker expression. These data cl...

Multilevel chitosan-gelatin particles loaded with P4HA1 siRNA suppress glioma development
Drug Deliv Transl Res. 2023 Sep 4. doi: 10.1007/s13346-023-01422-8. Online ahead of print.ABSTRACTIt has been reported that prolyl 4-hydroxylase subunit alpha 1 (P4HA1) promoted tumor growth and metastasis of glioma; thus, targeting P4HA1 may be a promising therapeutic strategy against glioma. In consideration of the instability of siRNA in vivo, the chitosan-gelatin microspheres loaded with P4HA1 siRNA (P4HA1 siRNA@CGM) were employed. Firstly, the gel electrophoresis and hemolytic test were performed to assess the stability and blood compatibility of P4HA1 siRNA@CGM. Then, methyl thiazolyl tetrazolium (MTT), cell colony f...

CHAC1 exacerbates arsenite cytotoxicity by lowering intracellular glutathione levels
J Toxicol Sci. 2023;48(9):487-494. doi: 10.2131/jts.48.487.ABSTRACTWe here examined whether CHAC1 is implicated in arsenite (As(III))-induced cytotoxicity in HaCaT cells. We found that HaCaT cells in which the intracellular GSH levels were elevated by transfection with CHAC1 siRNA showed decreased sensitivity to As(III) compared to the control cells. Treatment with BSO (an inhibitor of GSH biosynthesis) abolished the decrease in sensitivity to As(III), suggesting that an increase in intracellular GSH levels was involved in the decrease in sensitivity to As(III) due to the decrease in the levels of CHAC1 expression. When we...
