Objective: To explore the effect of propofol on H19 expression, migration and invasion of human breast cancer MDA-MB-231 cells in vitro.
Methods: MDA-MB-231 cells were randomly divided into 5 groups for treatment with basal medium, DMSO, or propofol at concentrations of 25, 50, and 100 µmol/L. H19 expression of the treated cells was assessed with RT-PCR, and the changes of cell motility, migration and invasion were evaluated with wound-healing assay and Transwell assays.
Results: Treatment of the cells with 25, 50, and 100 µmol/L propofol for 24 h down-regulated H19 by 17.83%, 37.50% and 63.67% (P<0.05), and suppressed cell motility by 13.46%, 36.54% and 46.17% (P<0.05), cell migration by 27.93%, 57.90% and 76.51% (P<0.05), and cell invasion by 25.72%, 53.32% and 81.43% (P<0.05), respectively.
Conclusion: Propofol-induced cell migration and invasion suppression are partially mediated by down-regulating H19 in MDA-MB-231 cells in vitro.

Background: Clear cell renal cell carcinoma (ccRCC) is the most common malignant urological tumor, and regrettably, and is insensitive to chemotherapy and radiotherapy, resulting in poor patient outcomes. DBF4 plays a critical role in DNA replication and participates in various biological functions, making it an attractive target for cancer treatment. However, its significance in ccRCC has not yet been explored.

Hepatocellular carcinoma (HCC) is a predominant cause of cancer-related mortality globally, noted for its propensity towards late-stage diagnosis and scarcity of effective treatment modalities. The process of metabolic reprogramming, with a specific emphasis on lipid metabolism, is instrumental in the progression of HCC. Nevertheless, the precise mechanisms through which lipid metabolism impacts HCC and its viability as a therapeutic target have yet to be fully elucidated.

Duchenne muscular dystrophy (DMD) is a lethal, muscle-wasting, genetic disease that is greatly amplified by an immune response to the diseased muscles. The mdx mouse model of DMD was used to test whether the pathology can be reduced by treatments with a CTLA4-Ig fusion protein that blocks costimulatory signals required for activation of T-cells. CTLA4-Ig treatments reduced mdx sarcolemma lesions and reduced the numbers of activated T-cells, macrophages and antigen presenting cells in mdx muscle and reduced macrophage invasion into muscle fibers.

The N6-methyladenosine (m6A) modification serves as an essential epigenetic regulator in eukaryotic cells, playing a significant role in tumorigenesis and cancer progression. However, the detailed biological functions and underlying mechanisms of m6A regulation in gastric cancer (GC) are poorly understood. Our research revealed that the m6A demethylase ALKBH5 was markedly downregulated in GC tissues, which was associated with poor patient prognosis.

In recent years, circRNAs have garnered increasing attention for their role in cervical cancer. However, the functions of many newly identified circRNAs remain unclear and require further exploration. In this study, we investigated the expression and oncogenic potential of the novel circRNA circSTX6 in cervical cancer.
