Article Synopsis
  • Cell division is tightly regulated, and the PomX/PomY/PomZ protein complex in Myxococcus xanthus plays a key role in organizing cytokinetic ring formation via the tubulin homolog FtsZ.
  • PomY forms liquid-like biomolecular condensates through phase separation, while PomX assembles into filaments to create a large cellular structure, ensuring the formation of one PomY condensate per cell.
  • PomY condensates selectively attract FtsZ, initiating its polymerization and guiding the formation of the FtsZ-ring necessary for cell division, indicating similarities to how eukaryotic microtubules are nucleated, hinting at an ancient evolutionary mechanism.

Thymoquinone has been proved to be effective against neoplasms, including skin cancer. Its high lipophilicity, however, may limit its potential use as a drug. Melanoma remains the deadliest of all skin cancers worldwide, due to its high heterogeneity, depending on the stage of the disease.

Melanoma is responsible for the highest number of skin cancer-caused deaths worldwide. Despite the numerous melanoma-treating options, the fight against it remains challenging, mainly due to its great heterogeneity and plasticity, as well as the high toxicity of standard drugs. Plant-derived terpenoids are a group of plant defense molecules that have been proven effective in killing many different types of cancer cells, both in in vitro experiments and in vivo models.

The outburst of inflammatory response and hypercoagulability are among the factors contributing to increased mortality in severe COVID-19 cases. Pentoxifylline (PTX), a xanthine-derived drug registered for the treatment of vascular claudication, has been reported to display broad-spectrum anti-inflammatory and immunomodulatory properties via adenosine A2A receptor (A2AR)-related mechanisms, in parallel to its rheological actions. Prior studies have indicated the efficacy of PTX in the treatment of various pulmonary diseases, including the management of acute respiratory distress syndrome of infectious causes.

Inflammatory bowel disease (IBD) is one of the leading gut chronic inflammation disorders, especially prevalent in Western countries. Recent research suggests that mitochondria play a crucial role in IBD development and progression to the more severe disease-colorectal cancer (CRC). In this review, we focus on the role of mitochondrial mutations and dysfunctions in IBD and CRC.
