A New Way to Starve Lung Cancers

We may soon be able to beat some lung cancers by targeting how tumors fuel themselves. Ohio State University oncologists found that certain non-small cell lung cancers (NSCLC) can survive treatment by activating a metabolic “backup system.” When one growth pathway is blocked, tumors increase glucose and fat metabolism to stay alive.

The OSU researcher discovered that hitting two targets at the same time foils this survival system. The targets are: the lysosomes that process cell nutrients; and SREBP-1, a protein that helps cancer cells absorb glucose and build fats. When both pathways are blocked in test tube and animal studies, tumor cells showed major metabolic stress and cell death.

One promising aspect is that several drugs used in this strategy already exist could help speed future clinical testing. They include chloroquine and simvastatin.

This finding is key since some lung cancers don’t respond to immunotherapy and lack targetable mutations, leaving patients with limited options. This new metabolic approach could open entirely different therapeutic pathways.

A targeted mRNA treatment restores sperm production in genetically infertile mice and allows them to father healthy offspring. This according to molecular biologists at Japan’s Kyoto University.

Messenger RNA, injected into the testes of male mice that carry a genetic defect which usually prevents sperm production, remains active for about two days and delivers vital instructions to both sperm-producing cells and support cells. Following this treatment, sperm collected from the mice successfully reverses infertility and produces healthy offspring through in-vitro fertilization.

Male factors drive infertility in roughly 40% of the 10% of couples worldwide who struggle to conceive. This is equal to females issues.

This mRNA fertility reversal is still in the stages of development, and clinical trials are needed to refine and determine the safety and effectiveness of the technique in humans. Hopefully, therapeutic mRNA might help couples suffering with infertility…… someday soon.

A new artificial-intelligence blood test, a higher tech liquid biopsy, may be able to detect silent liver disease years before symptoms appear. Oncologists at Johns Hopkins find that tiny fragments of DNA circulating in the bloodstream may contain hidden clues about early liver damage long before patients and their medical teams realize anything is wrong.

The researchers analyzed blood samples from 1,576 people using an AI system that studies patterns in cell-free DNA fragments. Each test evaluated about 40 million DNA fragments spread across the genome. Instead of searching for specific gene mutations, the technology looks at how these fragments are broken apart and distributed. Such patterns help identify early liver fibrosis and cirrhosis, conditions that often go undetected with current screening tools.

Liver disease affects an estimated 100 million Americans, and early stages are often silent without noticeable symptoms. Detecting liver scarring earlier could help doctors monitor patients and address underlying risk factors before serious complications and the need for a liver transplant develop.

While this test is still experimental and not yet ready for routine use in clinical care, it highlights how AI-based blood analysis may help identify hidden disease earlier in the future.
