🔬 UC San Diego biologists have developed a new CRISPR-based technology, pPro-MobV, to combat antibiotic resistance by neutralizing drug-resistant genes in bacterial populations.

🧬 Inspired by gene drive technology in insects, this second-generation tool can be introduced to a small number of bacteria to spread and disable resistance across a larger population.

🦠 The technology has shown success in tackling antibiotic resistance within bacterial biofilms, which are notoriously difficult to treat and contribute to disease spread in clinical and environmental settings.

Phage viruses can also deliver the pPro-MobV elements, working alongside engineered phage to combat resistance.

🔬 Researchers at Unil have discovered that tumors starved of vitamin B7 (biotin) become vulnerable. Biotin is essential for a mitochondrial enzyme that allows cancer cells to divide even without glutamine.

🧬 The gene FBXW7 plays a key role. When mutated (common in cancers), this enzyme becomes less active, forcing cancer cells to rely on glutamine.

💡 This finding could lead to new cancer therapies that target multiple metabolic pathways, bypassing resistance to current glutamine-targeting treatments.

🔬 CRISPR Breakthrough for Cancer Treatment: Utah State University (USU) biochemists have discovered that the CRISPR-Cas12a2 system can selectively destroy cells, offering a new potential approach to treating diseases like cancer without harming healthy tissue.

🧬 How it Works: Unlike other CRISPR systems, Cas12a2 uses a guide RNA to bind to RNA targets. When a perfect RNA match is found, Cas12a2 activates and shreds all DNA it encounters, effectively killing the cell. If the guide RNA isn't a perfect match, the cell is spared.

📊 Promising Results: Researchers demonstrated that Cas12a2 could selectively kill cancer cells with a specific mutation, leaving healthy cells untouched. In trials with mice, the therapy reduced tumor volume by approximately 50 percent after a single treatment.

🚀 Future Potential: This technology shows promise for selectively killing cells with specific gene mutations, viral genes, or other acquired changes, with potential applications in science, agriculture, and medicine.
