The Exocyst Complex is Required for the Trafficking and Delivery of KCa3.1 to the Basolateral Membrane of Polarized Epithelia
Am J Physiol Cell Physiol. 2023 May 1. doi: 10.1152/ajpcell.00374.2022. Online ahead of print.ABSTRACTControl of the movement of ions and water across epithelia is essential for homeostasis. Changing the number or activity of ion channels at the plasma membrane is a significant regulator of epithelial transport. In polarized epithelia, the intermediate-conductance calcium-activated potassium channel, KCa3.1 is delivered to the basolateral membrane where it generates and maintains the electrochemical gradients required for epithelial transport. The mechanisms that control the delivery of KCa3.1 to the basolateral membrane a...

ZBTB7C m6A modification incurred by METTL3 aberration promotes osteosarcoma progression
Transl Res. 2023 Apr 28:S1931-5244(23)00072-5. doi: 10.1016/j.trsl.2023.04.005. Online ahead of print.ABSTRACTAberrant N6-methyladenosine (m6A) modification of mRNAs contributes significantly to the epigenetic tumorigenesis, however, its precise role and the key targets in osteosarcoma (OS) are not defined. Here we reported that selective METTL3 (methyltransferase like 3) elevation and the consequential increase of m6A modification causally affect OS progression. The fast-growing OS cells displayed preferential upregulation of METTL3 and increased m6A modification. Conversely, m6A inhibition by 3-deazaadenosine, siRNA-medi...

Chitinase 3-like 1 induces cancer cell migration in solitary fibrous tumors
In this study, we found that chitinase 3-like 1 (CHI3L1), which induces cancer cell migration, was upregulated in NIH-3T3 cells that were transfected with the NAB2-STAT6 fusion gene. Moreover, the expression levels of the migration markers MMP2 and MMP9 were increased and the p-Akt level was also upregulated. In addition, it was observed that when CHI3L1 siRNA was transfected into NAB2-STAT6-transfected cells, cell migration and proliferation were reduced. Therefore, this study demonstrated that CHI3L1 activates Akt signaling to induce cell migration.PMID:37121124 | DOI:10.1016/j.bbrc.2023.04.057

Epigenetic regulation of DHRS2 by SUV420H2 inhibits cell apoptosis in renal cell carcinoma
In this study, we found that SUV420H2 is overexpressed in renal cancers and that high SUV420H2 expression is associated with a poor prognosis, as evidenced by RCC RNA-seq results derived from the TCGA. SUV420H2 knockdown using siRNA led to growth suppression and cell apoptosis in the A498 cell line. Furthermore, we identified DHRS2 as a direct target of SUV420H2 in the apoptosis process through a ChIP assay with a histone 4 lysine 20 (H4K20) trimethylation antibody. Rescue experiments showed that cotreatment with siSUV420H2 and siDHRS2 attenuated cell growth suppression induced by SUV420H2 knockdown only. Additionally, tre...

Nebivolol Sensitizes BT-474 Breast Cancer Cells to FGFR Inhibitors
CONCLUSION: Enhanced sensitivity of BT-474 breast cancer cells to nebivolol and erdafitinib was probably associated with down-regulation of AKT activation. Combined treatment with nebivolol and erdafitinib is a promising strategy for breast cancer treatment.PMID:37097659 | DOI:10.21873/anticanres.16357

p38 MAPK activation and STIM1-Orai3 association mediate TRPC6 externalization
Am J Physiol Cell Physiol. 2023 Apr 24. doi: 10.1152/ajpcell.00425.2022. Online ahead of print.ABSTRACTEndothelial cell (EC) migration is critical for the repair of monolayer disruption following angioplasties, but migration is inhibited by lipid oxidation products, including lysophosphatidylcholine (lysoPC), which open canonical transient receptor potential 6 (TRPC6) channels. TRPC6 activation requires an increase in intracellular Ca2+ concentration ([Ca2+]i), the source of which is unknown. LysoPC can activate phospholipase A2 to release arachidonic acid (ArA). ArA can activate arachidonic acid-regulated calcium (ARC) ch...
