IGF-1 receptor antagonism inhibits autophagy
Inhibition of the insulin/insulin-like growth factor signalling pathway increases lifespan and protects against neurodegeneration in model organisms, and has been considered as a potential therapeutic target. This pathway is upstream of mTORC1, a negative regulator of autophagy. Thus, we expected autophagy to be activated by insulin-like growth factor-1 (IGF-1) inhibition, which could account f...
متن کاملEffect of IGF-1 on Expression of GH Receptor, IGF-1, IGF-1 Receptor, KAP3.2 and KAP6-1 mRNA in the Skin of Sheep
Thirty-six healthy and similar Chinese Merino sheep were selected and divided into six groups at random. The treatment group was injected intradermally with 0.5 mL IGF-1 (10ng/mL). Treatment skin tissue of sheep were sampled respectively for 0,3,6,9,12 and 50 days and the skin expression of growth hormone receptor (GHR), insulin-like growth factor1 (IGF-1), insulin-like growth factor receptor (...
متن کاملGranzyme K Activates Protease-Activated Receptor-1
Granzyme K (GrK) is a trypsin-like serine protease that is elevated in patients with sepsis and acute lung inflammation. While GrK was originally believed to function exclusively as a pro-apoptotic protease, recent studies now suggest that GrK may possess other non-cytotoxic functions. In the context of acute lung inflammation, we hypothesized that GrK induces pro-inflammatory cytokine release ...
متن کاملIGFBP7 binds to the IGF-1 receptor and blocks its activation by insulin-like growth factors.
Insulin-like growth factor-binding protein 7 (IGFBP7) is a secreted factor that suppresses growth, and the abundance of IGFBP7 inversely correlates with tumor progression. Here, we showed that pretreatment of normal and breast cancer cells with IGFBP7 interfered with the activation and internalization of insulin-like growth factor 1 receptor (IGF1R) in response to insulin-like growth factors 1 ...
متن کاملGABAB Receptor Subunit GB1 at the Cell Surface Independently Activates ERK1/2 through IGF-1R Transactivation
BACKGROUND Functional GABA(B) receptor is believed to require hetero-dimerization between GABA(B1) (GB1) and GABA(B2) (GB2) subunits. The GB1 extracellular domain is required for ligand binding, and the GB2 trans-membrane domain is responsible for coupling to G proteins. Atypical GABA(B) receptor responses observed in GB2-deficient mice suggested that GB1 may have activity in the absence of GB2...
