Dynamic Involvement of Telocytes in Modulating Multiple Signaling Pathways in Cardiac Cytoarchitecture

Figure 1. An illustrative representation of the interlinking networks between WNT and TGFB signaling pathways. In the sketch are delineated the intricate protein–protein interaction latticeworks within cardiomyocytes and telocytes, showing a complementary synergism to induce cardiomyogenesis, cardiac regeneration, and pathogenesis of heart diseases. The figure is widely scrutinized in the main text. The black arrows designate main signaling pathways; the dashed arrows indicate activation; the continuous blunt-ended arrows pinpoint inhibition. APC: Adenomatous polyposis coli; BetaTrCP: Beta transducin repeats-containing protein; BMP: Bone morphogenetic protein; CAMKII: Calcium calmodulin-dependent protein kinase II; CK1: Casein kinase 1; DAAM: Disheveled-associated activator of morphogenesis; DAG: Diacylglycerol; DKK: Dickkopf; DVL: Dishevelled; FZD: Frizzled; GSK3B: Glycogen synthase kinase 3 beta; IP3: Inositol trisphosphate; JNK: c-Jun N terminal kinase; LGR5: Leucine-rich repeat-containing G-protein coupled receptor; LRP5/6: Lipoprotein receptor-related protein 5/6; NFAT: Nuclear factor of activated T-cells; PKC: Protein kinase C; PLC: Phospholipase C; RNF43: Ring finger protein 43;…

Figure 2. Illustration of the interconnecting networks between WNT, TGFB, PI3K/AKT/mTOR, and MAPK pathways. The figure is broadly discussed in the main text. The black arrows designate main signaling pathways; the dashed arrows indicate activation; the continuous blunt-ended arrows pinpoint inhibition. AKT: v-akt murine thymoma viral oncogene homolog/Protein kinase B; APC: Adenomatous polyposis coli; BMP: Bone morphogenetic protein; CK1: Casein kinase 1; FOXO1/3: Forkhead box proteins O1/3; FZD: Frizzled; GSK3B: Glycogen synthase kinase 3 beta; HF: heart failure; LRP5/6: Lipoprotein receptor-related protein 5/6; MAPK: Mitogen-activated protein kinase; mTOR: mammalian target of rapamycin; PI3K: phosphatidylinositol 3-kinase; PIP2: Phosphatidylinositol-4,5-bisphosphate; PIP3: Phosphatidylinositol-3,4,5-triphosphate; PTEN: Phosphatase and tensin homolog deleted on chromosome 10; ROCK: Rho-associated protein kinase; SMAD: Small mothers against decapentaplegic; TCF/LEF: T cell factor/Lymphoid enhancer factor; TGFB: Transforming growth factor beta.
