DNA damage responsive microRNAs misexpressed in human cancer regulate chemotherapy sensitivity (lung cancer cell lines)

ABSTRACT: The DNA damage response (DDR) is a cellular process that protects the genetic information against DNA damage and inhibits malignant transformation. Tumor cells are characterized by an aberrant DDR, which is exploited by genotoxic chemotherapy. However, cancer cells are able to develop drug resistance, for example by modulation of the DDR. Although the regulation of the DDR has been extensively studied, not much is known about the role of microRNAs (miRNAs). Here, we describe an approach to specifically identify DDR miRNAs in human primary epithelial cells that also play a role in tumorigenesis and response to cancer therapy in corresponding cancer cells.

DNA damage responsive microRNAs misexpressed in human cancer regulate chemotherapy sensitivity (HMEpC & HSAEpC)

Project description:The DNA damage response (DDR) is a cellular process that protects the genetic information against DNA damage and inhibits malignant transformation. Tumor cells are characterized by an aberrant DDR, which is exploited by genotoxic chemotherapy. However, cancer cells are able to develop drug resistance, for example by modulation of the DDR. Although the regulation of the DDR has been extensively studied, not much is known about the role of microRNAs (miRNAs). We used an approach to specifically identify DDR miRNAs in human primary epithelial cells that also play a role in tumorigenesis and response to cancer therapy in corresponding cancer cells. The miRNA expression profile was determined in 132 samples: 2 primary epithelial cell types, 1 untreated sample, 4 genotoxic treated samples, 3 timepoints, 4 replicates each and 6 zero timepoints for each cell type

Dissecting ubiquitylation and DNA damage response pathways in the yeast Saccharomyces cerevisiae using a proteome-wide approach

Project description:The proper function of DNA damage response pathways (DDR) is essential to protect eukaryotic cells from the accumulation of DNA damage and genome instability, a major cause of cancer and other diseases in humans. Ubiquitylation orchestrates the regulation of DDR events.Blaszczak et al. use quantitative proteomics and a reporter system based on the NanoLuc luciferase to study ubiquitylation and protein abundance changes upon genotoxic stress in yeast. The authors point out proteins that may be regulated by ubiquitylation during the DDR.

RNA-seq of OPI1 knockout yeast cells and the effect of methyl methanesulfonate (MMS) treatment relative to wild-type yeast cells with or without MMS treatment

Project description:Methyl methanesulfonate (MMS) is a DNA damage agent that induces the DNA damage response (DDR). Recent findings in the literature suggest a role for phosphatidylinositol signaling in regulating the DDR. In budding yeast, inositol biosynthesis is fine-tuned by the transcriptional repressor Opi1. We conducted RNA-seq of OPI1 knockout and wild-type yeast cells in conditions with or without treatment with 0.1% MMS for 1 hour to investigate the role of Opi1 in the response to genotoxic stress.
