Objective: To study the polymorphisms of cerebrovascular and cardiovascular disease genes using Taqman single nucleotide polymorphism (SNP) genotyping kits.
Methods: A total of 2000 subjects were recruited from the Guangzhou Biobank Cohort Study (GBCS), and 15 SNPs were detected using Taqman SNP genotyping kits and an ABI 7900HT real time PCR system. The data were tested for the Hardy-Weinberg equilibrium, and then compared with the data of the Chinese population from the International HapMap Project (HapMap_HCN).
Results: (1) All genotype data of the 15 SNPs were consistent with the Hardy-Weinberg rules. (2) The significant differences were observed among two SNPs, rs4220 and rs5368 and the HapMap_HCN (rs4220 28.2% vs 17.8%; chi(2) = 4.891, P = 0.028; rs5368 22.1% vs 32.2%, chi(2) = 5.137, P = 0.024). Comparing other gene bank data, such as AFD-CHN-PANEL, the Allele Frequency Database (ALFRED) and JBIC-allele, it would be most likely that our observations represent differences between the Northern and Southern populations in China.
Conclusion: Such Biobank study provided a useful platform for the study of the role of genetic and environmental determinants on cerebrovascular and cardiovascular disease.

Smoking cessation is a protective factor for lung cancer onset and mortality: a population-based prospective cohort study.
BMC Cancer

Department of Clinical Research, Sun Yat-Sen University Cancer Center, Guangzhou, 510060, Guangdong, P. R. China.
Background: Smoking is a pivotal modifiable risk factor for lung cancer (LC). Previous studies have indicated that a smoking cessation program might be incorporated into the LC screening program. However, the effects of smoking cessation and its duration with the age at onset (AAO) of LC, all-cause mortality, and LC-specific mortality remain unclear.

Background: Clonal hematopoiesis of indeterminate potential (CHIP) has been shown to be associated with the occurrence of solid tumors, but its relationship with colorectal cancer still needs to be studied.
Methods: We conducted a prospective matched case-control study using data from the UK Biobank, including 5,310 incident colorectal cancer (CRC) cases and 26,550 controls matched for age, sex, and body mass index (BMI).
Results: Analysis of the UK Biobank data revealed that the presence of CHIP was associated with an increased risk of CRC.
Silencing GRHL3 promotes multiple organ distant metastasis of lung squamous cell carcinoma cells by enhancing SOX2 stability via SIRT1.

Aberrant expression of grainyhead-like transcription factor 3 (GRHL3) has been extensively reported in the development and progression of several squamous cell carcinomas, such as cutaneous, head and neck, and esophageal squamous cell carcinoma. However, the clinical significance and biological roles of GRHL3 in lung squamous cell (LUSC) carcinoma are largely unclear. Herein, we report that GRHL3 was significantly upregulated in lung squamous epithelium of LUSC tissues, bronchiole, and bronchus.

Background: While optimal cardiovascular health (CVH) has been linked to a lower risk of dementia, few studies considered individuals' genetic background. We aimed to examine the interaction between CVH and genetic predisposition on dementia risk among individuals with atherosclerotic cardiovascular disease (ASCVD).
Methods: We included 30,818 ASCVD patients from the UK Biobank.

Insufficiency of Akkermansia muciniphila (Akk) has been implicated in the pathogenesis of metabolic diseases, and administration or restoration of Akk has ameliorated these disorders. Recently, Pasteurized Akk (PA-Akk) has been approved as a functional food. However, the impact of Akk on lipid absorption in the proximal intestine, which is directly exposed to orally administered Akk, remains largely unexplored.
