Short description of research:
The research focuses on understanding key molecular mechanisms in cancer, including the impact of sex differences, a high-fat diet, immune cells and the microbiome, using a combination of large-scale omic approaches, focused mechanistic experiments, and in vivo studies. A focus is colorectal cancers. The goal is to understand critical cancer pathways so that we can suggest better cancer treatments and preventive approaches and biomarkers to be tested and developed for clinical use.
The hormone estrogen can increase the risk of breast cancer, while simultaneously protect against colon cancer. It is not understood exactly how, but if we can achieve a detailed knowledge of this mechanism, we will be able to design approaches that can protect both men and women against colon cancer, without promoting breast cancer. Estrogenic signaling is mediated by the estrogen receptors, ERalpha and ERbeta. They are ligand-activated nuclear receptors and as such excellent therapeutic targets. Our research focuses on the estrogen-induced pathways in breast, ovarian, and colorectal cancer.
Related to this, is the identification of molecular mechanisms involving microRNAs and long non-coding RNAs. These molecules have great potential as novel biomarkers and therapeutic targets.
During the COVID-19 pandemic we were also involved in surveilling the outbreak through qPCR analysis of wastewater.
