Nevertheless, the functions and mechanisms are partly explored. Therefore, the present study analyzes the effect of circ_0006528 and the mechanism of regulation of NSCLC cell progression by sponging miR-892a to regulate neuroblastoma rat sarcoma viral oncogene (NRAS) expression. Initially, circ_0006528 is identified using divergent primers-based PCR and RNase R exonuclease treatments. After administration of the designed circ_0006528-specific siRNA, the RT-qPCR analysis is used to determine the interference efficiency of siRNA. At the same time, cell growth, invasion, and migration are assessed by 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT), Transwell, and scratch assays in the NSCLC cell lines [secretory pathway Ca2+-ATPase isoform 1 (SPCA-1) and A549] in vitro, respectively. Further, miR-892a inhibitor is added to the cells for functional recovery assay. Finally, the xenograft mouse model is constructed to explore the effect of circ_0006528 on tumor growth in vivo . The RT-qPCR analysis in 66 pairs of NSCLC cancer and noncancerous tissues revealed that circ_0006528 is highly expressed in NSCLC patient tissues. The RNase R experiments revealed that HSA_circ_0006528 is unaffected by RNase R exonuclease. MTT assay showed that knockdown of hsa_circ_0006528 by siRNA significantly decreased cell proliferation and viability in A549 and SPCA-1 cells. The luciferase reporter assay showed direct binding of hsa_circ_0006528 to miR-892a, and miR-892a targets binding NRAS. In addition, the miR-892a inhibitor terminated the hsa_circ_0006528 siRNA, triggering inhibition of proliferation, invasion, and migration of NSCLC cells.

Patients with pathologically confirmed EOC who underwent surgical treatment were included in this analysis. Immunohistochemistry was employed to evaluate FSP1 expression in ovarian tissues, with quantitative analysis performed on the samples. Clinical data were collected during follow-up, and patients were categorized according to platinum resistance and recurrence criteria. Statistical analysis was conducted using SPSS version 27.0. A total of 40 tissue samples from patients with EOC were analyzed, along with 21 samples from benign ovarian tumors and 20 samples from normal ovarian tissues. The expression of FSP1 was significantly higher in the EOC group compared to both benign and normal tissue groups. Meanwhile, the expressions of FSP1 were higher in groups with clinically advanced stages, high-grade carcinoma, presence of cancerous ascites, lymph node metastasis, and in the clear cell EOC group, compared to those with clinically early stages, low-grade carcinoma, absence of cancerous ascites, no lymph node metastasis, and other pathological subtypes. A positive linear correlation was identified between FSP1 expression in EOC tissues and serum levels of CA125 and human epididymis protein 4 at the time of diagnosis. The elevated expression of FSP1 is positively correlated with serum CA125 and human epididymis protein 4 levels at the time of diagnosis, which is a risk factor for EOC drug resistance and recurrence.

This study examines whether HER2 regulates autophagy in gastric cancer cells via the cGAS-STING signaling pathway, influencing key processes such as cell proliferation and migration. Understanding this relationship could uncover new molecular targets for diagnosis and treatment. Through lentiviral transfection, cell counting kit-8 assays, colony formation, transwell migration, scratch assays, and siRNA, we found that HER2 overexpression suppresses the cGAS-STING pathway, inhibits autophagy, and enhances the migratory ability of gastric cancer cells. In contrast, HER2 knockdown activates the cGAS-STING pathway, promotes autophagy, and reduces cell migration. We further observed that the inhibition of autophagy using chloroquine (CQ) increases the migration ability of HER2-overexpressing cells. Moreover, interfering with STING expression reversed the migration defects caused by HER2 knockdown, underscoring the critical role of the cGAS-STING pathway in HER2-regulated cell migration. We also revealed that high STING expression in gastric cancer is significantly associated with poor prognosis.
