Inward rectifying potassium channels sensitive to ATP levels (KATP) have been the subject of investigation for several decades. Modulators of KATP channels are well-established treatments for metabolic as well as cardiovascular diseases. Experimental studies have also shown the potential of KATP modulation in neurodegenerative disorders.

Article Synopsis
  • Matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) are crucial for cancer progression, affecting cell invasiveness by degrading the extracellular matrix, but their specific roles in brain tumors are not fully understood.
  • A study using quantitative real-time PCR found eight deregulated genes in glioblastoma patients compared to those with benign meningiomas, highlighting important differences in tumor aggressiveness.
  • Elevated MMP and TIMP protein levels were observed in glioblastoma patients, suggesting these proteins could be key players in gliomagenesis and potential targets for personalized cancer therapies, though further research is needed to confirm the relationship between gene expression and protein levels.

A brief period of transient global brain ischemia leads to selective ischemic neurodegeneration associated with death of hippocampal CA1 pyramidal neurons days after reperfusion. The mechanism of such selective and delayed neurodegeneration is still uncertain. Our work aimed to study the involvement of proteasomal and endoplasmic reticulum (ER) stress in ischemic neurodegeneration.

Background: Brain tumors are a heterogeneous group of malignancies characterized by inter- and intratumoral heterogeneity. Among them, the most aggressive and, despite advances in medicine, still incurable remains glioblastoma. One of the reasons is the high recurrence rate of the disease and resistance to temozolomide, a golden standard in chemotherapy of brain tumors.

Pyruvate carboxylase (PC) is an enzyme catalyzing the carboxylation of pyruvate to oxaloacetate. The enzymatic generation of oxaloacetate, an intermediate of the Krebs cycle, could provide the cancer cells with the additional anaplerotic capacity and promote their anabolic metabolism. Recent studies revealed that several types of cancer cells express PC.
