Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

DKK3 (REIC) is a secreted, N-glycosylated Dickkopf-family glycoprotein that functions as a context-dependent regulator of cell survival, differentiation, and Wnt/TGF-β signaling, acting predominantly as a tumor suppressor whose expression is lost in immortalized and tumor-derived cells (PMID:10652205, PMID:15516983). In cancer cells, restoring DKK3 triggers endoplasmic reticulum stress and JNK-dependent apoptosis, with mitochondrial Bax translocation and Bcl-2 loss, selectively in malignant but not normal cells (PMID:16266978, PMID:18922905); an N-terminal region is sufficient to drive ER stress and apoptosis (PMID:18727918), while the chaperones Hsp70/72 and ER-resident BiP/GRP78 set the threshold for this killing, with low levels conferring sensitivity (PMID:17549386, PMID:19626590). Downstream, ER-stress-induced ATF3 cooperates with Smad to repress Id-1 and activate JNK (PMID:18922905). DKK3 restrains Wnt/β-catenin signaling through multiple routes: blocking β-catenin nuclear accumulation and TCF-4 target genes c-Myc and cyclin D1 (PMID:18048388), direct β-catenin binding (PMID:34326879), and an intracellular isoform Dkk3b that sequesters cytoplasmic β-catenin with β-TrCP (PMID:28738084). It also suppresses TGF-β/Smad signaling by reducing TGF-β receptor levels and Smad2/3 phosphorylation (PMID:29843383, PMID:28458155). Beyond cancer, DKK3 controls differentiation and tissue homeostasis: it drives monocyte-to-dendritic-cell differentiation and STAT/GSK-3β phosphorylation via its cysteine-rich C-terminal domain (PMID:19212670, PMID:25823913), binds and inhibits ASK1 to block P38/JNK signaling in hepatocytes and improve insulin sensitivity (PMID:27016281), promotes smooth-muscle differentiation of vascular progenitors via TGF-β/ATF6 and Wnt (PMID:29284609), and acts as a paracrine inhibitor of muscle stem cell differentiation by enhancing nuclear β-catenin–FoxO3 transcription of the atrogenes Fbxo32 and Trim63 (PMID:29717119). Its transcription is controlled by activators (Pax6, FoxO4) and repressors (PRMT5-mediated histone methylation, MYC-miR-92a, Baf60c-Six4) (PMID:25029272, PMID:36106640, PMID:33462997, PMID:34593610, PMID:37284884). In HNSCC, DKK3 paradoxically acts as an oncogene through PI3K/Akt signaling independent of Wnt/TCF (PMID:28470144).
