Roles of G Protein-Coupled Receptors (GPCRs) in Gastrointestinal Cancers: Focus on Sphingosine 1-Shosphate Receptors, Angiotensin II Receptors, and Estrogen-Related GPCRs.

It is well established that gastrointestinal (GI) cancers are common and devastating diseases around the world. Despite the significant progress that has been made in the treatment of GI cancers, the mortality rates remain high, indicating a real need to explore the complex pathogenesis and develop more effective therapeutics for GI cancers. G protein-coupled receptors (GPCRs) are critical signaling molecules involved in various biological processes including cell growth, proliferation, and death, as well as immune responses and inflammation regulation.

The JAK/STAT signaling pathway: from bench to clinic.

The Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway was discovered more than a quarter-century ago. As a fulcrum of many vital cellular processes, the JAK/STAT pathway constitutes a rapid membrane-to-nucleus signaling module and induces the expression of various critical mediators of cancer and inflammation. Growing evidence suggests that dysregulation of the JAK/STAT pathway is associated with various cancers and autoimmune diseases.

Redox Control of the Dormant Cancer Cell Life Cycle.

Following efficient tumor therapy, some cancer cells may survive through a dormancy process, contributing to tumor recurrence and worse outcomes. Dormancy is considered a process where most cancer cells in a tumor cell population are quiescent with no, or only slow, proliferation. Recent advances indicate that redox mechanisms control the dormant cancer cell life cycle, including dormancy entrance, long-term dormancy, and metastatic relapse.

Dual-target inhibitors of bromodomain and extra-terminal proteins in cancer: A review from medicinal chemistry perspectives.

Bromodomain-containing protein 4 (BRD4), as the most studied member of the bromodomain and extra-terminal (BET) family, is a chromatin reader protein interpreting epigenetic codes through binding to acetylated histones and non-histone proteins, thereby regulating diverse cellular processes including cell cycle, cell differentiation, and cell proliferation. As a promising drug target, BRD4 function is closely related to cancer, inflammation, cardiovascular disease, and liver fibrosis. Currently, clinical resistance to BET inhibitors has limited their applications but synergistic antitumor effects have been observed when used in combination with other tumor inhibitors targeting additional cellular components such as PLK1, HDAC, CDK, and PARP1.

IL-30 ameliorates imiquimod and K14-VEGF induced psoriasis-like disease by inhibiting both innate and adaptive immunity disorders.
