MRes - Investigating the sex-dependent effects of macrophage insulin resistance on non-alcoholic fatty liver disease

Supervisors: Dr Matthew Gage and Dr Caroline Pellet-Many

Department: Comparative Biomedical Sciences

Project Details

Non-alcoholic fatty liver disease (NAFLD) is a spectrum of liver diseases in part driven by macrophages. Premenopausal females exhibit protection from NAFLD and macrophages express estrogen receptors which have been shown to augment and dampen innate immune signalling pathways. Risk factors for the development of NAFLD include obesity and insulin resistance however, the relationship between NAFLD, insulin resistance and macrophage function are unclear.

The aim of this MRes will be to explore the sex-dependent effects of insulin resistance in macrophages and how in turn this may impact NAFLD. The work proposed in this MRes will support an ongoing project within our Metabolic Hormones & Inflammation group.

Approach: This project will involve samples from mice, cell lines, and possibly human samples and incorporate a range of techniques including but not limited to: cell line and primary cell culture, PCR, genotyping, immunohistochemistry, histology, RT-qPCR, RNA Sequencing data analysis, Western blotting, in vitro functional assays.

Requirements

Essential:

  • Must meet our standard MRes entry requirements.

  • The candidate must be self-motivated, resilient and have a genuine interest in the cardiometabolic disease field.

Desirable:

  • Previous experience in a lab and/or basic molecular biology techniques and cell culture are desirable

This project will be full-time (12 months) commencing in October 2023. It will be based at RVC's Camden campus.

This project will utilise samples from genetically modified mice.

Funding

This project is partially funded: e.g. the lab will be covering the project costs, with the MRes student expected to meet the course fees and their living expenses.

You can find information on fees and funding online. A postgraduate master's loan may be available to help cover costs.
