Co-occurring mutations identify prognostic subgroups of microsatellite stable colorectal cancer.

Background: Co-occurring mutations in pairs of genes can pinpoint clinically relevant subgroups of cancer. Most colorectal cancers (CRCs) are microsatellite stable (MSS) and have few frequent mutations. Large patient cohorts and broad genomic coverage are needed for comprehensive co-mutation profiling.

Efficacity of hyperbaric oxygen therapy for necrotizing fasciitis in the maxillofacial region: The review of the literature.

Necrotizing fasciitis (NF) is a rare, dangerous, potentially fatal infectious disease of soft tissue. The treatment consists of antibiotic therapy, surgical debridement and subsequent reconstruction. Hyperbaric oxygen (HBO) therapy has been applied in NF patients recently, so our aim was to gather the findings and outcomes for HBO therapy.

The E3 ubiquitin ligase ITCH negatively regulates intercellular communication via gap junctions by targeting connexin43 for lysosomal degradation.

Intercellular communication via gap junctions has a fundamental role in regulating cell growth and tissue homeostasis, and its dysregulation may be involved in cancer development and radio- and chemotherapy resistance. Connexin43 (Cx43) is the most ubiquitously expressed gap junction channel protein in human tissues. Emerging evidence indicates that dysregulation of the sorting of Cx43 to lysosomes is important in mediating the loss of Cx43-based gap junctions in cancer cells.

Endocytic trafficking of connexins in cancer pathogenesis.

Gap junctions are specialized regions of the plasma membrane containing clusters of channels that provide for the diffusion of ions and small molecules between adjacent cells. A fundamental role of gap junctions is to coordinate the functions of cells in tissues. Cancer pathogenesis is usually associated with loss of intercellular communication mediated by gap junctions, which may affect tumor growth and the response to radio- and chemotherapy.
