Exploiting YES1-driven EGFR expression improves the efficacy of EGFR inhibitors.
Mol Cancer Res
January 2025
Cleveland Clinic, Cleveland, OH, United States.
Epidermal growth factor receptor (EGFR) is a highly expressed driver of many cancers, yet the utility of EGFR inhibitors is limited to cancers that harbor sensitizing mutations in the EGFR gene due to dose limiting toxicities. Rather than conventionally blocking the kinase activity of EGFR, we sought to reduce its transcription as an alternative approach to broaden the therapeutic window for EGFR inhibitors targeting wildtype or mutant EGFR. We found that YES1 is highly expressed in triple negative breast cancer (TNBC) and drives cell growth by elevating EGFR levels.

Background: Three dimensional (3D) cell cultures can be effectively used for drug discovery and development but there are still challenges in their general application to high-throughput screening. In this study, we developed a novel high-throughput chemotherapeutic 3D drug screening system for gastric cancer, named 'Cure-GA', to discover clinically applicable anticancer drugs and predict therapeutic responses.
Methods: Primary cancer cells were isolated from 143 fresh surgical specimens by enzymatic treatment.
Genetic etiology of Perrault syndrome in Iranian families: first report from Iran and literature review.

Perrault syndrome (PS) is an extremely rare autosomal recessive condition characterized primarily by bilateral sensorineural hearing loss in both genders and primary or secondary ovarian failure in females. Neurological features such as cerebral ataxia, peripheral neuropathy, epilepsy, and intellectual disability are frequent manifestations of PS. To date, six genes have been reported to cause PS, and nearly 100 families have been identified worldwide with this syndrome.

Metagenomes present a source for novel enzymes, but under 1% of environmental microbes are cultivatable. Because of its useful properties, Escherichia coli has been used as a host organism in functional genomic screens. However, due to differing expression machineries in the expression host compared to the source organism of the DNA sequences, screening outcomes can be biased.

A novel microfluidic platform was designed to study the cellular architecture of endothelial cells (ECs) in an environment replicating the 3D organization and flow of blood vessels. In particular, the platform was constructed to investigate EC defects in slow-flow venous malformations (VMs) under varying shear stress and flow conditions. The platform featured a standard microtiter plate footprint containing 32 microfluidic units capable of replicating wall shear stress (WSS) in normal veins and enabling precise control of shear stress and flow directionality without the need for complex pumping systems.
