miR-23b expression

The networks of miRNAs with their confirmed targets improved comprehension of miRNA-mediated therapeutic responses to trastuzumab and might be proposed for more characterization of miRNA functions. Moreover, these data indicated that miR-195-5p, miR-34c-3p, and miR-1246 could be possible biomarkers for prognosis and early detection of the trastuzumab-resistant group from the sensitive group of HER2-positive breast cancer patients.

Over-expression of miR-23b-3p could reverse Lnc-PLA2G4A-4 induced cell phenotypes in HCC and suppress versican expression of by rescue analysis. Collectively, Lnc-PLA2G4A-4 promotes HCC progression by targeting the miR-23b-3p/versican axis, which may be a potential biomarker and therapeutic target for HCC.

Overexpression of miR-30E-3p in NK cell-derived exosome inhibited the proliferation and invasion of NEC cells, and blocked cell cycle and promoted apoptosis, while knockdown miR-30e-3p in NK cell-derived exosomes did the opposite. Conclusion miR-30e-3p in NK cell-derived exosomes can inhibit the proliferation and invasion of ESCC cells, block their cell cycle and induce their apoptosis.

All in all, our data showed that miRNA-23b was highly expressed in the plasma of breast and gastric cancer but was low expressed in most types of cancer. In addition, miRNA -23b expression is significantly associated with poor overall survival in several cancer types and might be considered as a potential prognostic marker.

Analysis of The Cancer Genome Atlas (TCGA) database confirmed decreased levels of miR-23b, miR-125b-5p, and miR-199a-3p in EC. Decreased miR-23b expression was associated with worse survival of EC patients.

PLK2, PLK3, and ATM SNVs could potentially be helpful for the prediction of GC risk and clinicopathological features. PLK2 rs15009 affects the binding of miR-23b-5p. MiR-23b-5p expression status could serve as a prognostic marker for survival in patients with GC.

Our study highlights the cytoprotective role of autophagy and glutamine addiction modulated by miR-23b-3p (tumor suppressor), suggesting new approaches to curb sorafenib resistance in HCC.

Furthermore, miR-23b-3p overexpression hindered the growth of COAD cells in vivo. miR-23b-3p inhibited the oncogenicity of COAD cells in vitro and in vivo by directly targeting NFE2L3, suggesting the importance of the miR-23b-3p/NFE2L3 pathway in the development of COAD.

TRIM14 could promote the proliferation of AML cells via activating PI3K/AKT pathway, which was reversed by HMSC-exos through delivering miR-23b-5p. These findings indicated that miR-23b-5p and TRIM14 could be applied as potential targets for the treatment of AML.

In contrast, miR-133a was undetectable raising the hypothesys of an increased capacity of cells to translocate TRAIL receptors to the nucleus via clathrin and thus be resistant to TRAIL. The possible miR-133a ability to reduce clathrin expression may represent a novel approach for control of TRAIL apoptotic pathway and must be further investigated as a TRAIL sensitizing mechanism.
