Because induction of apoptosis involves complex interactions between many signaling pathways and arrangement of the highly sophisticated execution machinery of cell death, diverse antitumor strategies have been proposed to affect these interactions to preferentially kill tumor cells while sparing normal cells (1– 5).
The reason for this discrepancy between rodent and human cells is not obvious, as RA affects many signalling pathways that regulate cell differentiation.
The most abundant GO pathways include many signalling pathways (e.g., Wnt, TGF-beta, cadherin signalling, integrin signalling; Supplementary Data 4).
The work presented highlighted significant advances in understanding nucleocytoplasmic trafficking including how transport receptors and cargoes pass through the nuclear pore complex, the many signaling pathways that impinge on transport pathways, interplay between the nuclear envelope, nuclear pore complexes, and transport pathways, and numerous links between transport pathways and human disease.
Many signaling pathways, including the Wnt and Notch pathways, regulate intestinal stem cell maintenance, renewal and differentiation11,12. Intestinal homeostasis is secured by interdependent communication signals between the intestinal mucosal system along with IEC, the luminal environment with diet-derived and microbial products, as well as the microbiota.
GPCRs can activate many signaling pathways, either through interactions with heterotrimeric G proteins or through G protein-independent pathways.
Many signaling pathways may support the biology of stem cells.
