Targeting the Transforming Growth Factor-beta Signaling Pathway in the Treatment of Gynecologic Cancer.

The transforming growth factor-beta (TGF-β) signaling pathway has been reported to be dysregulated in the pathogenesis of several malignancies, including gynecologic cancers. This provides proof of concept of its potential value as a therapeutic target and prognostic biomarker in cervical cancer. Here we provide an overview of the biological role and clinical impact of TGF-β inhibitors either as a single agent or as a combinatorial therapy in gynecological cancers, concentrating on phase I to phase II/III clinical trials.

Molecular Aspects of Co-morbidities in COVID-19 Infection.

Coronaviruses are a group of enveloped viruses with single-stranded non-segmented positive-sense RNA genomes. In December 2019, SARS-CoV-2 appeared in China for the first time and quickly spread throughout the world. Although certain medications suggested for other afflictions tend to be potentially effective for curing the infection, there is no approved vaccination or drug available for this virus yet.

Association of cyclin-dependent kinase inhibitor 2A/B with increased risk of developing breast cancer.

There is a growing body of data reporting the association of genetic alterations in chromosome 9P21 with the risk of developing cancer. In the current study, we studied the association of a genetic variant in CDKN2A/B, rs1333049, with the risk of developing breast cancer. A total of 339 participants with and without breast cancer entered to the study.

A novel large germ line deletion in adenomatous polyposis coli (APC) gene associated with familial adenomatous polyposis.

Background: Familial adenomatous polyposis (FAP) is a familial colorectal cancer predisposition syndrome characterized by the development of numerous colorectal polyps, which is inherited in an autosomal dominant manner. FAP is caused by germ line mutations in adenomatous polyposis coli (APC) gene. Here, we described the identification of a causative APC gene deletion associated with FAP in an Iranian family.

Avascular Necrosis of the Femoral Head: Are Any Genes Involved?

Avascular necrosis of the femoral head (ANFH) is a pathologic process that results from interruption of blood supply to the femur bone resulting in the death of bone cells and collapse of the femoral head. Nontraumatic ANFH continues to be a significant challenge to orthopedic surgeons. While the exact mechanisms remain elusive, many new insights have emerged from research in the last decade that has given us a clearer picture of the pathogenesis of nontraumatic ANFH.
