Overexpression of multiple epidermal growth factor like domains 11 rescues anoikis survival through tumor cells-platelet interaction in triple negative breast Cancer cells.

Aims: The aim of this study was to test the hypothesis that overexpression of the Multiple Epidermal Growth Factor Like Domains 11 (MEGF11) gene in TNBC cells increases tumor cell survival against anoikis via interaction with platelets.

Main Methods: The role of MEGF11 was studied in human TNBC MDA-MB-231 and MDA-MB-468 cells by overexpressing MEGF11 (o/e MEGF11) using non-attached culture. Mouse wild type 4 T1 and Δmegf11-4 T1 cells were implanted into the mammary fat pad of BALB/c mice.

Postdiagnosis Aspirin Use Associated With Decreased Biliary Tract Cancer-Specific Mortality in a Large Nationwide Cohort.

Background And Aims: Biliary tract cancer (BTC) is rare and has limited treatment options. We aimed to examine aspirin use on cancer-specific survival in various BTC subtypes, including gallbladder cancer, ampulla of Vater cancer, and cholangiocarcinoma.

Approach And Results: Nationwide prospective cohort of newly diagnosed BTC between 2007 and 2015 were included and followed until December 31, 2017.

Interleukin 17A promotes cell migration, enhances anoikis resistance, and creates a microenvironment suitable for triple negative breast cancer tumor metastasis.

Background: The aim of this study was to investigate the role of IL-17A in the cancer microenvironment and the recurrence of triple negative breast cancer (TNBC).

Methods: Using human TNBC cell lines, the role of IL17-A was investigated by knocked down of IL-17A (ΔIL-17A) and by administration of IL-17A into the culture medium. Cell proliferation assays, migration assays, as well as Western blot analysis and real-time PCR, were used to evaluate IL-17A-related signaling.

MEGF11 is related to tumour recurrence in triple negative breast cancer via chemokine upregulation.

Our previous study demonstrated that upregulation of multiple epidermal growth factor-like domains 11 (MEGF11) gene expression is involved in the mechanism by which recurrence of Triple Negative Breast Cancer (TNBC) occurs. Our aim was to elucidate the role of MEGF11 expression in TNBC cells, both in vitro and in vivo, and in human tissue. Following MEGF11 gene knockdown (∆MEGF11) or over-expression in MDA-MB-231 and MB-468 cells, cell growth and chemokine gene expression were evaluated.
