Researchers have identified the molecular mechanisms behind two rare diseases: giant axonal neuropathy and ovarian cancer. In GAN, mutations in gigaxonin disrupt neural protein degradation, leading to neurofilament accumulation. Meanwhile, ATP11B facilitates cisplatin resistance in ovarian cancer cells by mediating platinum export.

Cancer cell metabolism kills

Researchers at the University of Helsinki discovered that the Myc oncoprotein makes cancer cells vulnerable to cell death by activating AMPK, a biochemical sensor. This leads to the activation of tumor suppressor protein p53, which promotes apoptosis in cancer cells.
