gestational diabetes | tooth Gestational diabetes mellitus affects odontoblastic differentiation of dental papilla cells via Toll-like receptor 4 signaling in offspring "Gestational diabetes mellitus (GDM) is an important factor involved in the pathogenesis of organ development in the offspring. Here, we analyzed the effects of GDM on odontoblastic differentiation of dental papilla cells (DPCs) and dentin formation in offspring and investigated their underlying mechanisms. A GDM rat model was induced by intraperitoneal injection of streptozotocin and offspring were collected. The results showed that GDM significantly affected odontoblast differentiation and dentin formation in offspring tooth. GDM activated the toll-like receptor 4 (TLR4)/nuclear factor-kappa B (NF-ĸB) signaling pathway and inhibited SMAD1/5/9 signaling to modulate the odontoblastic differentiation of DPCs in offspring. Inhibition of TLR4 signaling by treated with TAK-242 significantly reverses the suppression of odonto-differentiation of DPCs in diabetic offspring. Taken together, these data indicate GDM activated the offspring DPCs TLR4/NF-ĸB signaling, which suppressed the SMAD1/5/9 phosphorylation and then inhibited odontoblasts differentiation and dentin formation." tooth
Hippo Cyclin-Dependent Kinase 7 CDK7 regulates organ size and tumor growth by safeguarding the Hippo pathway effector Yki/Yap/Taz in the nucleus "Hippo signaling controls organ size and tumor progression through a conserved pathway leading to nuclear translocation of the transcriptional effector Yki/Yap/Taz. Most of our understanding of Hippo signaling pertains to its cytoplasmic regulation, but how the pathway is controlled in the nucleus remains poorly understood. Here we uncover an evolutionarily conserved mechanism by which CDK7 promotes Yki/Yap/Taz stabilization in the nucleus to sustain Hippo pathway outputs. We found that a modular E3 ubiquitin ligase complex CRL4DCAF12 binds and targets Yki/Yap/Taz for ubiquitination and degradation, whereas CDK7 phosphorylates Yki/Yap/Taz at S169/S128/S90 to inhibit CRL4DCAF12 recruitment, leading to Yki/Yap/Taz stabilization. As a consequence, inactivation of CDK7 reduced organ size and inhibited tumor growth, which could be reversed by restoring Yki/Yap activity. Our study identifies an unanticipated layer of Hippo pathway regulation, defines a novel mechanism by which CDK7 regulates tissue growth, and implies CDK7 as a drug target for Yap/Taz-driven cancer."

mammary gland Fry Is Required for mammary gland Development During Pregnant Periods and Affects the Morphology and Growth of Breast Cancer Cells "The Fry gene, located on chromosome 13, is an evolutionarily conserved large protein from yeast to human. Our previous study genetically linked the Fry gene with differential susceptibility to mammary carcinogenesis, but whether Fry affects mammary gland development and function, as well as the growth of breast cancer cells, is largely unknown. To define the consequences of Fry loss in the mammary glands, we have generated mice conditionally deficient of the Fry gene in the mammary glands using the Cre-loxP recombination system. We examined multiple phenotypes with male and female homozygous Fry conditional knockout mice (Mfry) and control mice (WT), including body weight, preliminary observations (health and neurological flexes), open field locomotion, sensory abilities, auditory threshold, and glucose metabolism. The loss of Fry in the mammary glands didn't cause a significant difference in these genotypes between Mfry and WT mice. However, our data showed that Fry was required during pregnancy, while it was functionally dispensable in virgin mammary gland development. Loss of Fry led to more lateral buds, and the lobuloalveoli were smaller and showed undistended morphology in mammary glands during late pregnancy. in vitro experiment, ectopic expression of FRY could alter the morphology and significantly suppress the growth and proliferation of the breast cancer cell lines, MDA-MB-231 (ER-/PR-/HER2-, Basal-like) and BT474 (ER+/PR+/HER2+, Luminal B). The following genome-wide transcriptomic analysis of these cells suggested that FRY interacted with protein kinases relevant signaling pathways and induced massive changes in gene expression, including the activation of the Hippo/Yap pathway. Together, our data suggest that the FRY is required for mammary glands developments during pregnant periods, and affects breast cancer cell growth and proliferation."
