Article Abstract
Aim: The objective of this study was to investigate the pooled prevalence and possible association between polyomavirus infection and lung cancer.
Methods: A systematic publication search was conducted by identifying relevant cross-sectional and case-control studies from major online databases. Heterogeneity, OR, and corresponding 95 % CI were applied to all studies through meta-analysis and forest plot. Random effects models were used to calculate the overall pooled prevalence. Visual inspection of a funnel plot plotting the log-transformed OR and its associated standard error of the log (OR) was combined with the Begg and Egger test to examine the presence and influence of publication bias. Analyzes were performed using Stata software v.14.1.
Results: 23 articles (33 datasets) were included in the meta-analysis, of which 14 datasets were case/control and the rest were cross-sectional studies. The pooled polyomavirus infection rate in lung cancer patients was 0.06 % (0.02-0.11 %). In subgroup analysis, the pooled prevalence of JCV, MCPyV, KI, SV40, BKV, WU, MU, and STL was 21 %, 7 %, 6 %, 2 %, 0 %, 0 %, 0 %, and 0 % respectively. An association has been found between polyomavirus infection and lung cancer [summary OR 6.33 (95 % CI (1.76-22.77); I2=67.45 %)]. The subgroup analysis, based on the virus type, showed a strong association between MCPyV and lung cancer [summary OR 13.61 (95 % CI 2.41-76.59; I2=40.0 %)]. despite the high prevalence of JCV DNA in lung cancer tissue, analysis of case-control studies showed that JCV is not associated with lung cancer and does not increase the risk of lung cancer.
Conclusion: This study showed a significant association between polyomaviruses infection with lung cancer. The results also revealed a pooled prevalence of 6 % for polyomaviruses in lung tumor patients. Altogether, the findings of the present work suggest that Merkel cell polyomavirus infection is a potential risk factor for lung cancer.

Purpose: Lung cancer is currently the most common malignant tumor worldwide and one of the leading causes of cancer-related deaths, posing a serious threat to human health. MicroRNAs (miRNAs) are a class of endogenous non-coding small RNA molecules that regulate gene expression and are involved in various biological processes associated with lung cancer. Understanding the mechanisms of lung carcinogenesis and detecting disease biomarkers may enable early diagnosis of lung cancer.

Objective: CircRNAs are involved in cancer progression. However, their role in immune escape in non-small cell lung cancer (NSCLC) remains poorly understood.
Methods: This study employed RIP-seq for the targeted enrichment of circRNAs, followed by Western blotting and RT-qPCR to confirm their expression.

Aberrant DNA methylation has been described in nearly all human cancers, yet its interplay with genomic alterations during tumor evolution is poorly understood. To explore this, we performed reduced representation bisulfite sequencing on 217 tumor and matched normal regions from 59 patients with non-small cell lung cancer from the TRACERx study to deconvolve tumor methylation. We developed two metrics for integrative evolutionary analysis with DNA and RNA sequencing data.

Five new heterodimers, chalasoergodimers A-E (1-5), and three known heterodimers (6-8), along with four chaetoglobosin monomers (9-12), were isolated from a marine-derived Chaetomium sp. fungus. The structures of new compounds 1-5 were elucidated by HRESIMS, NMR, chemical calculated C NMR and ECD methods.
