In embryonic development, Goosecoid plays a central role in regulating cell migration events and patterning. It is crucial for organizing the early embryo, where it is activated downstream of key signaling molecules such as TGF‑β/activin and Nodal and functions both as a transcriptional repressor and activator to refine cell fates (see."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "1", "end_ref": "3"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn addition to its developmental role, Goosecoid is implicated in pathological processes. In human breast cancer cells, for instance, ectopic expression of Goosecoid promotes epithelial–mesenchymal transition and enhances invasive and metastatic behaviors, partly by modulating TGF‑β signaling pathways. Similarly, during craniofacial development, Goosecoid interacts with proteins such as the E3 ubiquitin ligases Wwp2 and APC(Cdh1) to control the transcription of key cartilage regulatory genes, thereby ensuring proper patterning of skeletal structures (see."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "4", "end_ref": "6"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nMechanistically, the regulation of Goosecoid involves both transcriptional control and post‑translational modifications. Within embryonal carcinoma cells, Goosecoid transcription is activated by a complex interplay between TFII‑I and SMAD2 upon TGF‑β/activin stimulation, while related factors such as BEN can oppose its activation. Furthermore, post‑translational modifications, notably SUMOylation, fine‑tune Goosecoid’s repressive activity in a promoter‑specific manner, thus influencing its ability to regulate key developmental genes and affect cell morphology (see."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "7"}]}, {"type": "t", "text": "\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Ana C Borges, Sara Marques, José A Belo "}, {"type": "b", "children": [{"type": "t", "text": "Goosecoid and cerberus-like do not interact during mouse embryogenesis."}]}, {"type": "t", "text": " "}, {"type": "i", "children": [{"type": "t", "text": "Int J Dev Biol (2002)"}]}, {"type": "t", "text": " PMID: "}, {"type": "a", "children": [{"type": "t", "text": "11934155"}], "href": "https://pubmed.ncbi.nlm.nih.gov/11934155"}]}, {"type": "r", "ref": 2, "children": [{"type": "t", "text": "Manching Ku, Sergei Y Sokol, Jack Wu, et al.
