Genetic biomarkers could personalise therapy for TNBC

Drug Discovery World

A new study has shed light on the genetic messages encoded by genes within ‘triple negative’ breast cancers (TNBC), and shows they could predict response to chemotherapy. “Our findings paint a complex picture – with many, dynamic factors driving how tumours respond to treatment.”

Genetically modified mice pave the way for customized medicine in a rare disease

Medical Xpress

Ana Guadaño at the Alberto Sols Biomedical Research Institute (IIBM, a combined CSIC-UAM center) and involving the Complutense University of Madrid (UCM), used CRISPR gene editing techniques to incorporate into mice a mutation of the MCT8 protein responsible for transporting thyroid hormones to the interior of the cell.

Black women with breast cancer may have worse outcomes than peers despite similar genetic recurrence scores

Medical Xpress

Non-Hispanic Black women with hormone receptor (HR)-positive/HER2-negative, lymph node-positive breast cancer had worse outcomes compared to non-Hispanic whites, Asians, and Hispanics, despite similar 21-gene recurrence scores, according to a study presented at the 2022 San Antonio Breast Cancer Symposium, held December 6-10, 2022.

The FDA’s Guidance on Gene Edited Foods + What American Foods are Banned in Other Countries? – Xtalks Food Podcast Ep. 149

XTalks

In this episode of the Xtalks Food Podcast, Sydney talks about gene edited foods and how this landmark guidance aims to demystify the FDA’s risk-based approach towards both genome edited foods and all new plant varieties. Genome editing stands as a cutting-edge technique that ingeniously introduces new traits into plants.

NICE rejects prostate cancer drug due to cost of genetic testing

Drug Discovery World

The National Institute of Health and Care Excellence (NICE) has confirmed its decision not to recommend olaparib for previously treated metastatic prostate cancer in patients with BRCA gene mutations. NICE has judged olaparib too expensive partly because of the cost of genetic testing to tailor the drug for patients.
