Article Abstract
Background: Although it has been shown that cyclin dependent kinase inhibitor 2A (CDKN2A) plays a significant role in a number of malignancies, its clinicopathological value and function in small cell lung cancer (SCLC) is unclear and warrants additional research.
Methods: The clinical significance of CDKN2A expression in SCLC was examined by multiple methods, including comprehensive integration of mRNA level by high throughput data, Kaplan-Meier survival analysis for prognostic value, and validation of its protein expression using in-house immunohistochemistry.
Results: The expression of CDKN2A mRNA in 357 cases of SCLC was evidently higher than that in the control group (n = 525) combing the data from 20 research centers worldwide. The standardized mean difference (SMD) was 3.07, and the area under the curve (AUC) of summary receiver operating characteristic curve (sROC) was 0.97 for the overexpression of CDKN2A. ACC, COAD, KICH, KIRC, PCPG, PRAD, UCEC, UVM patients with higher CDKN2A expression had considerably worse overall survival rates than those with lower CDKN2A expression with the hazard ratio (HR) > 1.
Conclusion: CDKN2A upregulation extensively enhances the carcinogenesis and progression of SCLC.

Immune checkpoint inhibitors (ICIs) can re-active the immune response and induce a complete response in mismatch repair-deficient and microsatellite instability-high (dMMR/MSI-H) colorectal cancer (CRC). However, most CRCs exhibit proficient mismatch repair and microsatellite stable (pMMR/MSS) phenotypes with limited immunotherapy response because of sparse intratumoral CD8 T-lymphocyte infiltration. Cellular senescence has been reported to involve immune cell infiltration through a senescence-associated secretory phenotype (SASP).

To investigate the clinicopathological characteristics of well-differentiated papillary mesothelial tumor (WDPMT). Sixteen cases of resected WDPMTs diagnosed at the Affiliated Hospital of Qingdao University, Qingdao, China from 2017 to 2024 were collected and the clinicopathological features were retrospectively analyzed. There were 7 males amd 9 females, with a mean age of 53.

Background: TERT promoter mutation is a rare biomarker in meningiomas associated with aberrant TERT expression and reduced progression-free survival. Although high TERT expression is characteristic of tumours with TERT promoter mutations, it has also been observed in tumours with wildtype TERT promoters. This study aimed to investigate the prevalence and prognostic association of TERT expression in meningiomas.

We investigated the influence of 55,583 autophagy-related single nucleotide polymorphisms (SNPs) on chronic lymphocytic leukemia (CLL) risk across four independent populations comprising 5,472 CLL cases and 726,465 controls. We also examined their impact on overall survival (OS), time to first treatment (TTFT), autophagy flux, and immune responses. A meta-analysis of the four populations identified, for the first time, significant associations between CDKN2A (rs3731204) and BCL2 (rs4940571, rs12457371, rs1026825) SNPs and CLL risk, with CDKN2A showing the strongest association (p=1.

Background And Objectives: Cell lines serve as invaluable tools in studying lung cancer biology and developing new therapies to combat the disease. However, commercially available cell lines are typically of Caucasian origin and may be less representative of the local genetic background. To address this, our lab previously immortalized cells from pleural fluid of a Filipino non-small cell lung cancer (NSCLC) patient via CDK4 transduction.
