Poly(C)‑binding protein 2 (PCBP2) is a member of the PCBP family, and plays an important role in post‑transcriptional and translational regulation of various signaling molecules through direct binding to single‑stranded poly(C) motifs. PCBP2 has been reported to play a critical role in the development of multiple human tumors. However, whether PCBP2 participates in hepatocellular carcinoma (HCC) development remains largely elusive. Herein, we showed that PCBP2 was upregulated in human HCC tissues and cell lines. Overexpression of PCBP2 predicted significantly worsened prognosis in HCC patients, suggesting that PCBP2 may serve as a prognostic marker of HCC. In addition, we found that depletion of PCBP2 inhibited HCC cell proliferation, accompanying the increase in the cyclin‑dependent kinase inhibitor p27 level. Moreover, we found that high expression of PCBP2 may contribute to sorafenib resistance in HCC cells, involving dysregulated expression of Bax and Bcl‑2 proteins. In conclusion, our results suggest that PCBP2 may serve as a prognostic marker and potential therapeutic target of HCC.

The EGFR-driven angiogenesis is crucial in solid tumors, particularly through the delivery of biomolecules via extracellular vesicles (EVs), but the mechanism by which EGFR regulates EV cargo is still unclear. First, cell co-culture and murine tumor models were employed to examine the impact of EGFR overexpression on the pro-angiogenic properties of small EVs (sEVs) derived from oral squamous cell carcinoma (OSCC). Small RNA sequencing was then used to compare the miRNA profiles of OSCC-sEVs with and without EGFR overexpression, followed by functional enrichment and motif analyses of the differentially expressed miRNAs.

Ovarian cancer (OC) is a malignant gynecological cancer with an extremely poor prognosis. Stress granules (SGs) are non-membrane organelles that respond to stressors; however, the correlation between SG-related genes and the prognosis of OC remains unclear. This systematic analysis aimed to determine the expression levels of SG-related genes between high- and low-risk groups of patients with OC and to explore the prognostic value of these genes.

Objective: This study aims to elucidate the mechanisms by which nanovesicles (NVs) transport curcumin(CUR) across the blood-brain barrier to treat hypothalamic neural damage induced by heat stroke by regulating the expression of poly(c)-binding protein 2 (PCBP2).
Methods: Initially, NVs were prepared from macrophages using a continuous extrusion method. Subsequently, CUR was loaded into NVs using sonication, yielding engineered cell membrane Nanovesicles loaded with curcumin (NVs-CUR), which were characterized and subjected to in vitro and in vivo tracking analysis.

Massive numbers of modified bases in mRNAs sculpt the epitranscriptome and play vital roles in RNA metabolism. The only known acetylated RNA modification, N-4-acetylcytidine (acC), is highly conserved across cell types and among species. Although the GCN5-related acetyltransferase 10 (NAT10) functions as an acC writer, the mechanism underlying the acetylation process is largely unknown.
