Knockdown of CCNB1 alleviates high glucose-triggered trophoblast dysfunction during gestational diabetes via Wnt/β-catenin signaling pathway.

Gestational diabetes mellitus (GDM), defined as glucose intolerance occurring or first detected during pregnancy, affects approximately 8% of pregnancies worldwide. The dysfunction of trophoblasts in pregnancies complicated by GDM is associated with changes in trophoblast cell functions, resulting in compromised proliferation and regulation of the cell cycle. Cyclin B1 (CCNB1), a pivotal controller of the start of mitosis, is crucial in these mechanisms.

Metabolic reprogramming and signaling adaptations in anoikis resistance: mechanisms and therapeutic targets.

Anoikis, a form of programmed cell death triggered by detachment from the extracellular matrix (ECM), maintains tissue homeostasis by removing mislocalized or detached cells. Cancer cells, however, have evolved multiple mechanisms to evade anoikis under conditions of ECM detachment, enabling survival and distant metastasis. Studies have identified differentially expressed proteins between suspended and adherent cancer cells, revealing that key metabolic and signaling pathways undergo significant alterations during the acquisition of anoikis resistance.
