Background/aim: Melanoma, a variant of skin cancer, presents the highest mortality rates among all skin cancers. Despite advancements in targeted therapies, immunotherapies, and tissue culture techniques, the absence of an effective early treatment model remains a challenge. This study investigated the impact of dabrafenib on both 2D and 3D cell culture models with distinct molecular profiles.

Genetic association studies in rheumatoid arthritis conducted in various populations have yielded heterogeneous results. The present systematic review was conducted to synthesize the results of the studies in order to establish the impact of polymorphisms in the ficolin-coding genes FCN1, FCN2, and FCN3 on the susceptibility to develop rheumatoid arthritis. A systematic literature review was performed using the following keywords "gene (FCN1/FCN2/FCN3)", "Polymorphism/Genetic Variant", and "rheumatoid arthritis" in different databases until January 2022.

Article Synopsis
  • The study aimed to investigate the relationship between CDKN2A and CDK4 gene variations and melanoma in a Colombian population.
  • DNA samples were collected from 85 melanoma patients and 166 healthy controls, and gene variants were analyzed using a specific assay.
  • Results indicated no significant differences in CDKN2A variants between patients and controls, but a specific haplotype (500G/540C) was associated with a higher melanoma risk, particularly in males with a family cancer history.

Ovarian cancer is the fifth leading cause of cancer-related deaths. It causes approximately 125,000 deaths per year worldwide; its diagnosis is made in advanced stages resulting in a high mortality rate. The objective of the study was optimizing the isolation of cells obtained from the solid tumor and ascitic fluid of patients with ovarian cancer and the phenotype with markers related to the epithelial-mesenchymal transition.
