The aim of our project is to improve research capacity in low- and middle-income countries by harnessing the expertise of native-speaking scientists and fostering collaboration with professionals in industrialized countries. With this approach, we aim to contribute to brain gain by writing success stories that empower local researchers, drive innovation and promote sustainable development in their home countries.
Our project focuses on improving research capacity in low- and middle-income countries by providing accessible, cost-effective methods to study gene polymorphisms associated with colorectal cancer and precancerous lesions. Our goal here is to empower local researchers by introducing simple techniques, such as polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) analysis, that are both feasible and affordable in these regions. By enabling the testing of genetic markers in colorectal cancer, this initiative will promote early detection and a better understanding of cancer risks and ultimately contribute to better healthcare in resource-limited areas.
The principal aim of the current study was to investigate the relationship between miR-149 T>C (rs2292832) and miR-196a2 C>T (rs11614913) small non-coding RNA polymorphisms and the risk of developing CRC in the Azerbaijani population. The study included 120 patients diagnosed with CRC and 125 healthy individuals. Peripheral blood samples were collected from all the subjects in EDTA tubes and DNA extraction was performed by salting out. Polymorphisms were determined using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.
While comparing without gender distinction no statistical correlation was found between the heterozygous TC (OR = 0.66; 95% CI = 0.37–1.15; p = 0.142), mutant CC (OR = 1.23; 95% CI = 0.62–2.45; p = 0.550), and mutant C (OR = 1.03; 95% CI = 0.72–1.49; p = 0.859) alleles of the miR-149 gene and the CT (OR = 1.23; 95% CI = 0.69–2.20; p = 0.485), mutant TT (OR = 1.29; 95% CI = 0.67–2.47; p = 0.452), and mutant T (OR = 1.17; 95% CI = 0.82–1.67; p = 0.388) alleles of the miR-196a2 gene and the risk of CRC. However, among women, miR-149 TC (OR = 0.43; 95% CI = 0.19–1.01; p = 0.048) correlated with a reduced risk of CRC, whereas miR-196a2 CT (OR = 2.77; 95% CI = 1.13–6.79; p = 0.025) correlated with an increased risk of CRC. Our findings indicated that miR-149 T>C (rs2292832) might play a protective role in the development of CRC in female patients, whereas the miR-196a2 (rs11614913) polymorphism is associated with an increased risk of CRC in women in the Azerbaijani population, highlighting the importance of gender dimorphism in cancer etiology.
