Oral squamous cell carcinoma (OSCC) is characterized by rapid local migration and invasion. This study was aimed at clarifying the effect of miR-654-5p on progression of OSCC. miR-654-5p promoted proliferation, metastasis, and chemoresistance of OSCC in vitro and in vivo. Consistently, miR-654-5p was upregulated in late-stage OSCC and was correlated with poor prognosis of OSCC patients. Furthermore, miR-654-5p was mechanistically verified to target Grb-2-related adaptor protein (GRAP), accompanied by the activation of Ras/MAPK signaling and the facilitation of epithelial-mesenchymal transition in OSCC cells. GRAP was downregulated in T1-2 stage versus T3-4 stage head and neck squamous cell carcinoma (HNSC) and was negatively correlated with tumor-node-metastases (TNM) stage in HNSC patients based on The Cancer Genome Atlas (TCGA) analysis. In addition, GRAP was positively correlated with good prognosis in HNSC patients. Our findings suggest that the miR-654-5p/GRAP/Ras/Erk signaling pathway in OSCC cells might contribute to the underlying mechanism through which miR-654-5p participates in the regulation of OSCC progression. miR-654-5p, as a potential biomarker for the clinical diagnosis and prognosis of OSCC, may be an effective anticancer target for the treatment of OSCC.

Background: Dysfunction in podocyte mitophagy has been identified as a contributing factor to the onset and progression of diabetic nephropathy (DN), and BMAL1 plays an important role in the regulation of mitophagy. Thus, this study intended to examine the impact of BMAL1 on podocyte mitophagy in DN and elucidate its underlying mechanisms.
Materials And Methods: High D-glucose (HG)-treated MPC5 cells was used as a podocyte injury model for investigating the potential roles of BMAL1 in DN.

Background: Bok is a poorly characterized Bcl-2 protein family member with roles yet to be clearly defined. It is clear, however, that Bok binds strongly to inositol 1,4,5-trisphosphate (IP) receptors (IPRs), which govern the mobilization of Ca from the endoplasmic reticulum, a signaling pathway required for many cellular processes. Also known is that Bok has a highly conserved phosphorylation site for cAMP-dependent protein kinase at serine-8 (Ser-8).

Early-onset (EOCC) and late-onset cervical cancers (LOCC) represent two clinically distinct subtypes, each defined by unique clinical manifestations and therapeutic responses. However, their immunological profiles remain poorly explored. Herein, we analyzed single-cell transcriptomic data from 4 EOCC and 4 LOCC samples to compare their immune architectures.

Background: Head and neck squamous cell carcinoma (HNSCC), a highly invasive malignancy with a poor prognosis, is one of the most common cancers globally. Circular RNAs (circRNAs) have become key regulators of human malignancies, but further studies are necessary to fully understand their functions and possible causes in HNSCC.
Methods: CircCCT2 expression levels in HNSCC tissues and cells were measured via qPCR.

Background: Hepatocellular carcinoma (HCC) is a prevalent primary liver malignancy and a leading cause of cancer-related mortality worldwide. Despite advancements in therapeutic strategies, the 5-year survival rate for individuals undergoing curative resection remains between 10% and 15%. Consequently, identifying molecular targets that specifically inhibit the proliferation and metastasis of HCC cells is critical for improving treatment outcomes.
