Article Abstract
Background/aim: The disruption of cell-cycle control can lead to an imbalance in cell proliferation, often accompanied by genomic instability, which in turn can facilitate carcinogenesis. This study aimed to examine the impact of CDKN1A rs1801270 and rs1059234 polymorphisms on the risk of childhood acute lymphocytic leukemia (ALL) in Taiwan.
Materials And Methods: The genotypes of CDKN1A rs1801270 and rs1059234 in 266 childhood ALL cases and 266 controls were determined using PCR-RFLP techniques.
Results: The genotypic and allelic frequencies for CDKN1A rs1801270 and rs1059234 did not significantly differ between childhood ALL cases and controls (all p>0.05). However, stratified analysis revealed that the CDKN1A rs1801270 AA variant was associated with a reduced risk of childhood ALL in males (OR=0.40, 95%CI=0.20-0.82, p=0.0178). Additionally, the AC and AA genotypes of rs1801270 were linked to a lower risk classification for childhood ALL and longer survival times (OR=0.57 and 0.31, 95%CI=0.33-0.97 and 0.18-0.56, p=0.0538 and 0.0001, respectively). No significant associations were found for rs1059234 in the stratified analyses (p>0.05 for all).
Conclusion: Although CDKN rs1801270 and rs1059234 genotypes were not associated with an overall risk of childhood ALL, CDKN1A rs1801270 polymorphism may serve as a protective predictor in males and as a potential marker for better prognosis of childhood ALL. Validation in larger and more diverse populations is necessary to confirm the feasibility of this predictor.

Objective: N6-methyladenosine (m A) is a common epigenetic modification in eukaryotes. In this study, we explore the potential impact of m A-associated single nucleotide polymorphisms (m A-SNPs) on heart failure (HF).
Methods: Data from genome-wide association studies (GWAS) investigating HF in humans and from m A-SNPs datasets were used to identify HF-associated m A-SNPs.

Background: This study delves into the intricate landscape of oral cancer, a global concern with a high incidence in Asian countries. We focus on oral squamous cell carcinoma (OSCC), primarily driven by the consumption of betel nut and its derivatives. OSCC often arises from premalignant lesions like oral submucous fibrosis (OSF).

Background: The p53 and p21 proteins are important regulators of cell cycle and apoptosis and may contribute to autoimmune diseases, such as systemic lupus erythematosus (SLE). As genetic polymorphisms may cause changes in protein levels and functions, we investigated associations of TP53 and p21 (CDKN1A) polymorphisms (p53 72 G > C-rs1042522; p53 PIN3-rs17878362; p21 31 C > A-rs1801270; p21 70 C > T-rs1059234) with the development of systemic lupus erythematosus (SLE) in a Southeastern Brazilian population.
Methods: Genotyping of 353 female volunteers (cases, n = 145; controls, n = 208) was performed by polymerase chain reaction, restriction fragment length polymorphism and/or DNA sequencing.

Article Synopsis
- - A case-control study in rural Maharashtra examined the connection between certain genetic variations (polymorphisms) in tumor suppressor genes p21 and p53 and breast cancer risk among women, involving 800 participants (400 breast cancer patients and 400 healthy controls).
- - The study specifically focused on four single nucleotide polymorphisms (SNPs) in the p21 and p53 genes and utilized PCR-RFLP methods to analyze blood samples, assessing the genetic risk factors using odds ratios and logistic regression.
- - Results showed that specific polymorphisms in the p21 gene, particularly the rs1801270 SNP, were negatively associated with breast cancer risk, indicating that certain genetic variations may offer some level of protection in
