Summary: This study found that using IGF-1 concentrations at 6 weeks postoperatively can effectively predict surgical outcomes in acromegaly patients, with most patients able to assess clinical outcomes through this method.

Summary: Discordance between GH and IGF-1 levels in acromegaly patients is influenced by GH cutoff values. The use of GH(m) can mitigate the impact of GH cutoffs and improve predictive accuracy. Fasting GH levels (both GH(f) and GH(m)) are poor predictors of IGF-1 normalization in this cohort.

Summary: Sleep latency is the time it takes to enter sleep, and shorter sleep latencies may indicate excessive daytime sleepiness and pathological sleep conditions. This study reviewed normative values of mean sleep latency from 110 healthy adult cohorts and analyzed the impact of demographic and methodological variables. The results suggest that there were no significant associations between mean sleep latency and these variables, but a negative association was found between mean sleep latency and apnea-hypopnea index on prior night polysomnography.

Summary: IGF-1, the principal mediator of GH, plays a crucial role in cell growth, differentiation, and apoptosis, with its bioavailability affected by IGFBPs. The varying expression levels of IGF-1 in clinical conditions and its misuse in sports have raised significant concerns.

Summary: Human insulin-like growth factor-1 (IGF-1) and its analog Long R3 IGF-1 (LR3 IGF-1) were successfully recombinantly expressed and produced in the Pichia pastoris expression system by fusion with highly expressed xylanase XynCDBFV. The purified IGF-1 and LR3 IGF-1 displayed excellent bioactivity of cell proliferation compared to the standard IGF-1. Furthermore, high heterologous expression levels of the fusion proteins were achieved by fermentation in a 15-L bioreactor, which could be used for both clinical and scientific applications.

Summary: This study investigated the exposure of Iranian adults to polyaromatic hydrocarbons (PAHs) and found high concentrations of 1-hydroxypyrene metabolites in urine samples. The urinary concentrations of 1-hydroxypyrene metabolites were positively associated with body composition, BMI, and age, with BMI showing a significant relationship.

Summary: This study investigated the exposure to 1-hydroxypyrene in healthy Iranian adults and found higher concentrations compared to similar studies in other countries. These results provide valuable information for the interpretation of biomonitoring results in Iran.

Summary: This study reveals the direct link between N-glycosylation defects found in Congenital Disorders of Glycosylation (CDG) and the impairment of IGF-1/IGF-1R signaling components. The study indicates that deficiencies in N-glycosylation affect IGF-1 secretion and IGF-1R expression, leading to reduced IGF-1 availability and local activity in CDG patients.

Summary: IGF-1 activates intracellular signaling pathways by binding to IGF-1R, including PI3K/AKT and MAPK pathways, to regulate cell proliferation and apoptosis. The IGF-1 signaling also promotes cell differentiation and proliferation through the Ras/MAPK pathway.

Summary: This study investigated the expression of insulin-like growth factor 1 (IGF-1) and IGF-1 type 1 receptor (IGF-1R) in skeletal muscle fiber types in chickens with hepatic fibrosis induced by bile duct ligation (BDL). The results showed that hepatic fibrosis caused a significant decrease in the cross-sectional area (CSA) of myofibers in the pectoralis muscles, while the CSA in the femorotibialis lateralis muscle did not decrease. Furthermore, type I fibers expressed both IGF-1 and IGF-1R and exhibited hypertrophy.

Summary: In this study, continuous reference ranges for body composition parameters were derived using multiple regression analysis. The results showed that age had a minor impact on FMI, VAT, and ALSTI, while BMI substantially increased the explained variance for these parameters. On the other hand, age was a major determinant of the explained variance for SMI, with BMI also contributing. These findings are important for body composition evaluation in overweight and older individuals.

Summary: Prostate cancer (PCa) is a highly heterogeneous disease driven by gene alterations and microenvironmental influences. IGF-1 and its receptor IGF-1R have emerged as vital drivers in the development of PCa. Inhibitory reagents targeting IGF-1/IGF-1R signaling have shown promise in limiting cancer development, but further research and clinical trials are needed.
