Cell–cell adhesion-induced patterning in keratinocytes can be explained by just starvation and strong adhesion, Hokkaido University researchers find.

Researchers from Osaka University have shown that a system known as the GET pathway is essential for efficient mitophagy, the process by which mitochondria are removed from cells. The GET pathway targets a protein assembly called the Ppg1–Far complex, which inhibits mitophagy, to the membrane of a part of the cell called the endoplasmic reticulum. When the GET pathway is defective, this complex instead becomes targeted to mitochondria, where it acts to suppress mitophagy.

A recent study conducted by the Faculty of Medicine at The Chinese University of Hong Kong (CU Medicine) discovered a novel genetic biomarker which can predict the survival of head and neck cancer patients. There are over 0.7 million new head and neck squamous cell carcinoma (HNSCC) cases globally each year. However, currently there is no clinical implementation of any genetic biomarker to predict outcomes for these patients after standard treatment. A study led by Professor Vivian Wai Yan LUI, an expert in genomic medicine and Associate Professor of the School of Biomedical Sciences at CU Medicine, and her research team, has identified that mitogen activated protein kinase (MAPK) pathway mutations found in almost 20% of HNSCC patients can predict favourable clinical outcomes with standard therapy. Their survival also doubled when compared with other patients. The finding has just been published in the journal Life Science Alliance.

Pathogenic gene mutations causing a type of intractable skin disease can be eliminated from some parts of patients’ skin as they age, according to Hokkaido University researchers and their collaborators in Japan. This represents a form of natural gene therapy.
