Ovarian granulosa cell tumors (GCTs) are rare gynecologic tumors in women. Due to the rarity and limited research efforts invested, the etiology of GCTs remains poorly defined. A landmark study has discovered the mutation of forkhead box L2 (FOXL2) as a genetic hallmark of adult GCTs in the human. However, our understanding of the role of cell signaling in GCT development is far from complete. Increasing lines of evidence highlight the importance of TGF-beta (TGFB) superfamily signaling in the pathogenesis of GCTs. This review draws on findings using genetically modified mouse models and human patient specimens and cell lines to reveal SMAD3 activation as a potentially key converging point of dysregulated TGFB superfamily signaling and genetic aberrations in GCT development. It is anticipated that deciphering the role of TGFB superfamily signaling cascades in ovarian tumorigenesis will help develop new therapeutic approaches for GCTs by targeting core signaling elements essential for tumor initiation, growth, and progression.

Dinucleases of the DEDD superfamily, such as oligoribonuclease, Rexo2 and nanoRNase C, catalyze the essential final step of RNA degradation, the conversion of di- to mononucleotides. The active sites of these enzymes are optimized for substrates that are two nucleotides long, and do not discriminate between RNA and DNA. Here, we identified a novel DEDD subfamily, members of which function as dedicated deoxydinucleases (diDNases) that specifically hydrolyze single-stranded DNA dinucleotides in a sequence-independent manner.

The FAT atypical cadherin 1 (FAT1) gene is the ortholog of the fat gene and encodes the protocadherin FAT1. FAT1 belongs to the cadherin superfamily, a group of full-length membrane proteins that contain cadherin-like repeats. In various types of human cancer, FAT1 is one of the most commonly mutated genes, and is considered to be an emerging cancer biomarker and a potential target for novel therapies.

Inhibin, β, which is also known as INHBA, encodes a protein that belongs to the Transforming Growth factor-β (TGF-β) superfamily, which plays a pivotal role in cancer. Gastrointestinal tract (GI tract) cancer refers to the cancers that develop in the colon, liver, esophagus, stomach, rectum, pancreas, and bile ducts of the digestive system. The role of INHBA in all GI tract cancers remains understudied.

Neuropeptide (abbreviated as ) is a recently discovered peptide that is present in many arthropods and is the ligand of the , a member of the G protein-coupled receptors (GPCRs) superfamily, which plays a regulatory role in diverse physiological processes such as feeding, circadian rhythm, insulin production, lipid metabolism, growth, and reproduction. However, the function of this gene in aphids is still unknown. Here, we characterized and determined the potential role of / signaling in the pea aphid, , which is a notorious pest in agriculture.

The receptor for advanced glycation end-products (RAGE), a member of the immunoglobulin superfamily, is expressed in various cell types and mediates cellular responses to a wide range of ligands. The activation of RAGE triggers complex signaling pathways that drive inflammatory, oxidative, and proliferative responses, which are increasingly implicated in the pathogenesis of skin diseases. Despite its well-established roles in conditions such as diabetes, cancer, and chronic inflammation, the contribution of RAGE to skin pathologies remains underexplored.
