Mesenchymal Stem Cells Combined With IFNγ Induce Apoptosis of Breast Cancer Cells Partially Through TRAIL.

Background: Mesenchymal stem cells (MSCs) have gained remarkable attention because of their ability to dualistically regulate tumor growth. The main objective of this study was to evaluate the apoptotic effects of human bone marrow-derived (hBM) MSCs in combination with interferon gamma (IFN-γ) on MCF-7 breast cancer cells, and to determine the cytokines involved in the apoptotic process.

Materials And Methods: hBM-MSCs were co-cultured with MCF-7 cells either directly and indirectly for 72 h in-vitro.

LGALS3 and AXIN1 gene variants playing role in the Wnt/ β-catenin signaling pathway are associated with mucinous component and tumor size in colorectal cancer.

The Wnt pathway alterations have been identified in colorectal and many other cancer types. It has been reported that galectin-3 (which is encoded by the LGALS3 gene) alters the signaling mechanism in the Wnt/ β-catenin pathway by binding to β-catenin in colon and other cancers. AXIN1 is mainly responsible for the assembly of the β-catenin destruction complex in the Wnt pathway.

Individual and Combined Effects of CTLA4-CD28 Variants and Oxidant-Antioxidant Status on the Development of Colorectal Cancer.

Background: Colorectal cancer (CRC) is the third most frequent cancer worldwide. Research has revealed the contributions of the immune system and anti-inflammatory pathways in the development of cancer. The balance between cluster of differentiation 28 (CD28) and cytotoxic T-lymphocyte-associated protein 4 (CTLA4) signaling is important for the regulation of immune responses.

Distribution and Effects of CDKN2 p16 540 C>G and 580 C>T, and MDM2 SNP309 T>G Polymorphisms in Patients with Primary Brain Tumors.

Background/aim: Primary brain tumors are unique tumors due to their different pathobiological behavior, while they rarely metastasize outside the central nervous system. Regarding the oncogenesis of primary brain tumors, it was shown that changes in functions of p16 and mouse double minute 2 homolog (MDM2) are related to tumor pathogenesis by enhancing cell proliferation and malign development. The present study aims to evaluate the possible associations between cyclin-dependent kinase 2 (CDKN2) p16 540 C>G and 580 C>T, MDM2 single nucleotide polymorphism 309 (SNP309) T>G polymorphisms and primary brain tumor.
