RAD52 is a DNA repair protein identified by University of Iowa researchers as crucial for cancer cell survival, particularly in cells with BRCA1/2 mutations that impair DNA repair mechanisms. By inhibiting RAD52, researchers can selectively kill cancer cells without heavily affecting normal cells. This approach offers a promising alternative to PARP inhibitors, potentially overcoming drug resistance and reducing side effects associated with traditional treatments like chemotherapy and radiation, thereby opening new therapeutic avenues for cancers with DNA repair deficiencies.

Researchers from Nagaland University have identified Sinapic acid, a naturally occurring plant compound, as a promising therapeutic agent for treating diabetic wounds. Their study marks the first global evidence showing that oral administration of Sinapic acid can significantly accelerate wound healing under diabetic conditions in preclinical models. This discovery holds immense potential for developing affordable and effective treatments for chronic wounds commonly seen in diabetic patients, contributing to advancements in medical research and promoting health innovation from India’s northeastern region.

Russia’s Federal Medical-Biological Agency (FMBA) announced a significant breakthrough by unveiling a colon cancer vaccine during the Eastern Economic Forum (EEF) 2025. The vaccine demonstrated promising results in preclinical trials, with a 60–80% reduction in tumour size, improved survival rates, and no recorded adverse effects. It specifically targets colorectal cancer, which is one of the world’s leading causes of cancer-related deaths. If approved by regulators, this would become Russia’s first immunotherapy treatment for colorectal cancer. Furthermore, FMBA is also working on developing vaccines for glioblastoma and melanoma, marking a major stride in cancer research and treatment.

The World Health Organisation has reclassified Hepatitis D Virus (HDV) as carcinogenic due to its strong association with liver cancer. Hepatitis D is a defective virus that requires the Hepatitis B Virus (HBV) for replication and transmission. It can cause co-infection or superinfection in HBV patients, raising the risk of cirrhosis and hepatocellular carcinoma by 2–6 times compared to HBV alone. Though its prevalence in India is considered low, it may be underreported, especially in high-risk groups. Prevention relies mainly on universal Hepatitis B vaccination, alongside safe medical practices, blood screening, and targeted surveillance in vulnerable populations.

A major new study has found that vitamin D deficiency may play a significant role in the development of psychological and neurodevelopmental conditions. The research highlights that low vitamin D levels are not only a personal health concern but also a biological factor that can be passed down through generations, potentially affecting brain development as well as bone health. Conducted in Denmark, the study's conclusions are also consistent with clinical observations in countries like India. This reinforces the importance of maintaining adequate vitamin D levels, especially during pregnancy and early childhood, to support both mental and physical health.
