    Abstract Objectives: Bladder Cancer (BC) is one of the most commonly diagnosed malignancies worldwide, with high rates of mortality and morbidity. It can be classified as non-muscle invasive bladder cancer (NMIBC) or muscle-invasive bladder cancer (MIBC), with radical cystectomy being the treatment for MIBC, which significantly reduces quality of life. MicroRNAs (miRs) act as critical genetic regulators, with both oncogenic and tumor-suppressive roles. MiR-10a is described as a tumor suppressor in various neoplasms, but its role in BC is controversial. This study aims to assess the activity of miR-10a in cellular invasion and proliferation in two… More >

    The role of tazarotene-induced gene 1 in carcinogenesis: is it a tumor suppressor gene or an oncogene?

    Abstract Tazarotene-induced gene 1 (TIG1) is induced by a derivative of vitamin A and is known to regulate many important biological processes and control the development of cancer. TIG1 is widely expressed in various tissues; yet in many cancer tissues, it is not expressed because of the methylation of its promoter. Additionally, the expression of TIG1 in cancer cells inhibits their growth and invasion, suggesting that TIG1 acts as a tumor suppressor gene. However, in some cancers, poor prognosis is associated with TIG1 expression, indicating its protumor growth characteristics, especially in promoting the invasion of inflammatory breast cancer More >
