Matrix metalloproteinase-2 delivery to extracellular vesicles produced by HPV-positive cervical cancer cells enhances metastasis via the Akt pathway
Cell Biol Int. 2023 Jun 5. doi: 10.1002/cbin.12054. Online ahead of print.ABSTRACTHere, we aimed to analyze the effects of matrix metalloproteinase-2 (MMP-2) delivery to extracellular vesicles (EVs) secreted by human papillomavirus (HPV)-associated cervical cancer cells on human umbilical vein endothelial cell (HUVEC) angiogenesis. First, MMP-2 expression was compared among SiHa (HPV16), HeLa (HPV18), and C-33A (negative) cells. Then, EVs were isolated from these cells, and MMP-2 expression in the EVs was compared. SiHa and HeLa cells were transfected with MMP-2 or control siRNA. HUVECs were treated with EVs isolating from...

HPV E6 promotes cell proliferation of cervical cancer cell by accelerating accumulation of RBM15 dependently of autophagy inhibition
This study explored the role of methyltransferase components in HPV-related cervical cancer and the mechanism. The levels of methyltransferase components and autophagy, ubiquitylation of RBM15 protein and the co-localization of lysosomal markers LAMP2A and RBM15 were measured. CCK-8 assay, flow cytometry, clone formation experiment and immunofluorescence assay were conducted to measure cell proliferation. The mouse tumor model was developed to study the cell growth in vivo. The binding of RBM15 to c-myc mRNA and m6A modifcation of c-myc mRNA were analyzed. The expressions of METTL3, RBM15 and WTAP were higher in HPV-positi...

The role of tribbles homolog 2 in vascular smooth muscle cell proliferation
Cell Biol Int. 2023 Jan 10. doi: 10.1002/cbin.11982. Online ahead of print.ABSTRACTTribbles homolog 2 (TRIB2) functions as an adapter protein that regulates signal transductions involved in a variety of cellular functions, including tumorigenesis. However, the role of TRIB2 in the proliferation of vascular smooth muscle cells (VSMCs) and the underlying expression mechanisms remain unclear. The present study investigated the role of TRIB2 in VSMC proliferation and revealed that TRIB2 expression increases following vascular injury and platelet-derived growth factor (PDGF)-BB-stimulated VSMCs. We found that pretreatment with ...

Significance of Oct-4 transcription factor as a pivotal therapeutic target for CD44 < sup > + < /sup > /24 < sup > - < /sup > mammary tumor initiating cells: Aiming at the root of the recurrence
In this study, we have attempted to identify previously unrecognized CSC survival factors that can be used as druggable targets for bCSCs apoptosis regulators isolated from the TNBC line, MDA MB 468. After a thorough literature review, Oct-4 was identified as the most promising marker for its unique abundance in cancer and absence in normal cells and the contribution of Oct-4 to the sustenance of cancer cells. We then validated a very high expression of Oct-4 in the MDA MB 468 bCSCs population using flow-cytometry. The loss of Oct-4 was carried out using small interfering RNA (siRNA)-mediated knockdown in the bCSCs, follow...
