Background: The correlation between at-risk polymorphisms in genes of base excision repair (BER) pathways and lung cancer (LC) risk was newly considered but still not clear, a systematic review and updated meta-analysis was performed in the current study.
Methods: We identified and recorded the eligible publications from Google Scholar, PubMed, Medicine and Web of Science. For all calculates, odds ratios (ORs) and 95% confidence intervals (CIs) were applied to estimate the potential relationship between these genetic variants and LC risk. Subsequently, Begg's funnel plot and Egger's test were used to appraising the publication bias.
Results: A total of 202 case-control studies extracted from 116 publications were enrolled. Firstly, we analyzed six polymorphisms in , the overall analysis results of homozygote and recessive models illustrated that rs3213245 polymorphism was remarkably linked to an upgrade LC risk. Then, in the subgroup analysis stratified by ethnicity, we uncovered a meaningfully raised risk of LC in Asian population in homozygote and recessive models for rs3213245 polymorphism, as well as in the allelic contrast, heterozygous and dominant models for rs915927 polymorphism. For -rs1760944 polymorphism, the overall analysis suggested a significantly decreased risk. Another gene was , we identified a significantly upregulated risk in recessive model of -rs1052133 polymorphism for LC.
Conclusions: -rs3213245 and -rs1052133 polymorphisms are risk factors for LC, while -rs1760944 polymorphism is a protective factor.

Background: Oral cancer screening programs can aid in the early identification of potentially malignant oral lesions. The objective of the present study was to evaluate the effectiveness of the Oral Rub and Rinse (ORR) technique as an oral cancer screening tool and to test its potential in detecting genetic alterations in exfoliated cells obtained through ORR.
Methods: The screening programs were conducted in rural Dakshina Kannada and Udupi districts in Karnataka.

Background: In this study we explored the association of polymorphisms of glutathione s transferase gene including GSTM1, GSTT1 and GSTP1 with adverse acute normal tissue reactions resulted from radiotherapy in HNC patients. We assessed the association of GSTM1 and GSTT1 null genotypes and Ile105Val of exon-5 and Ala114Val of exon-6 of GSTP1 gene polymorphisms with the risk of acute skin toxicity reactions after therapeutic radiotherapy in HNC patients.
Methods: Four hundred HNC patients administered with Intensity modulated radiation therapy were enrolled in this study for the evaluation of radiotherapy associated toxicity reactions.

Background: Litter size in mice is an important fitness and economic feature that is controlled by several genes and influenced by non-genetic factors too. High positive selection pressure in each generation for Litter size at birth (LSB), resulted in the development of high and low prolific lines of inbred Swiss albino mice (SAM). Despite uniform management conditions, these lines showed variability in LSB across the generation.

A complex regulatory network governs fruit ripening, but natural variations and functional differentiation of fruit ripening genes remain largely unknown. Utilizing a genome-wide association study (GWAS), we identified the NAC family transcription factor MdNAC18.1, whose expression is closely associated with fruit ripening in apple (Malus × domestica Borkh.
