Feed your microbiome and your heart: The gut-heart axis.

Cardiovascular and metabolic diseases are the leading causes of disability, morbidity, and mortality worldwide. Genetics plays an important role, but environmental factors change the game and hold the potential for prevention, reversibility, and applied therapy. Nutrition, phenotype, and behavior of microorganisms, intestinal eco-events, and intestinal permeability play a crucial role in the induction of diseases.

Functional mismatch repair and inactive p53 drive sensitization of colorectal cancer cells to irinotecan via the IAP antagonist BV6.

A common strategy to overcome acquired chemotherapy resistance is the combination of a specific anticancer drug (e.g., topoisomerase I inhibitor irinotecan) together with a putative sensitizer.

Sensitization of colorectal cancer cells to irinotecan by the Survivin inhibitor LLP3 depends on XAF1 proficiency in the context of mutated p53.

Survivin is a well-established target in experimental cancer therapy. While hardly expressed in normal tissues, it is over-expressed in most human tumors, including colorectal cancer (CRC). Different compartmentalization of Survivin enables its multiple functions as a key controller of cell division, apoptosis, stress-induced signaling and also of migration and metastasis.

Integrin αVβ3 silencing sensitizes malignant glioma cells to temozolomide by suppression of homologous recombination repair.

Integrins have been suggested as possible targets in anticancer therapy. Here we show that knockdown of integrins αVβ3, αVβ5, α3β1 and α4β1 and pharmacological inhibition using a cyclo-RGD integrin αVβ3/αVβ5 antagonist sensitized multiple high-grade glioma cell lines to temozolomide (TMZ)-induced cytotoxicity. The greatest effect was observed in LN229 cells upon integrin β3 silencing, which led to inhibition of the FAK/Src/Akt/NFκB signaling pathway and increased formation of γH2AX foci.
