IGF1 protein, human

Insulin-like growth factor I (IGF1) is a polypeptide protein that plays a crucial role in human growth and development.
It is produced primarily by the liver and is essential for regulating cell proliferation, differentiation, and metabolism.
IGF1 exerts its effects through binding to specific cell surface receptors, triggering downstream signaling cascades that influence a variety of physiological processes.
Researchers studying IGF1 protein can utilize the PubCompare.ai platform to optimize their research, locating the best protocols and products from literature, pre-prints, and patents using AI-driven comparisons to ensure reproducible science.
This tool can help streamline IGF1 protein research effeciently, uncovering the power of this invaluable resource.

Two data sets are used as examples, both of height in puberty. The first, the Christ’s Hospital School (CHS) cohort, consisted of a sample of 3245 boys, who attended the school at some stage between 1939 and 1968 and were measured twice a term between the ages of 9 and 19 years [median 42 measurements per boy, inter-quartile (IQR) range 35–47, range 1–63], a total of 129 508 heights. These were linked to follow-up data on 1520 adults, some 50 years later, when inter alia height and insulin-like growth factor 1 (IGF-1) levels were measured. The cohort has been described in detail previously,7–9 and an inverse association between age at peak height velocity (APHV) and later IGF-1 has been reported.9 (link) This was based on estimates of APHV for each child derived from spline curves fitted to each child’s data.
The second data set came from a randomized clinical trial of oxandrolone to increase final height in girls with Turner syndrome (TS). This is a chromosomal disorder where the second X chromosome is missing or malformed, leading to short stature and primary ovarian failure. A total of 106 girls with TS already on a standard dose of growth hormone were randomized to receive either oxandrolone or placebo from the age of 9 years (or the age at recruitment if later) until final height was reached. One girl dropped out immediately and 13 more later on, whereas 92 girls remained in the study and 82 had reached final height before the time of analysis. A total of 1321 heights were included in the analysis (median 12 per child, IQR 9–17, range 1–23). The trial, which also included a second randomization to early or late oestrogen for induction of puberty, is reported in detail elsewhere (EJ Gault et al., submitted for publication).

To generate MNPs, hPSCs were dissociated with Dispase (1 mg/ml) and split 1:6 on irradiated MEFs or Matrigel coated plates. On the following day, the PSC medium was replaced with a chemically defined neural medium, including DMEM/F12, Neurobasal medium at 1:1, 0.5×N2, 0.5×B27, 0.1mM ascorbic acid (Santa Cruz), 1×Glutamax and 1×penicillin/streptomycin (All others from Invitrogen). CHIR99021 (3uM, Torcris), 2μM DMH-1 (Torcris) and 2μM SB431542 (Stemgent) were added in the medium. The culture medium was changed every other day. Human PSCs maintained under this condition for 6 days were induced into NEP cells. The NEP cells were then dissociated with Dispase (1 mg/ml) and split at 1:6 with the same medium described above. RA (0.1μM, Stemgent) and 0.5μM Purmorphamine (Stemgent) were added in combination with 1μM CHIR99021, 2μM DMH-1, and 2μM SB431542. The medium was changed every other day. NEP cells maintained under this condition for 6 days differentiated into OLIG2+ MNPs. The OLIG2+ MNPs were expanded with the same medium containing 3μM CHIR99021, 2μM DMH-1, 2μM SB431542, 0.1μM RA, 0.5μM Purmorphamine and 0.5 mM VPA (Stemgent), and split 1:6 once a week with Dispase (1 mg/ml). OLIG2+ MNPs were frozen with the regular frozen medium (DMEM/F12, 10% fetal bovine serum and 10% DMSO) in liquid nitrogen, and cultured again in expansion medium after thawing.
To induce MN differentiation, OLIG2+ MNPs were dissociated with Dispase (1 mg/ml) and cultured in suspension in the above neural medium with 0.5μM RA and 0.1μM Purmorphamine. The medium was changed every other day. OLIG2+ MNPs under this condition for 6 days differentiated into MNX1+ MNs. The MNX1+ MNs were then dissociated with Accumax (eBioscience) into single cells and plated on Matrigel coated plates or on astrocytes. The MNX1+ MNs were cultured with 0.5μM RA, 0.1μM Purmorphamine and 0.1μM Compound E (Calbiochem) for 10 days to mature into CHAT+ MNs. Insulin-like growth factor 1(IGF-1), brain-derived neurotrophic factor (BDNF), and ciliary neurotrophic factor (CNTF) (all from R&D, 10 ng/ml each) were added if MNs were plated at low density. For identifying MN disease phenotypes, SMA and ALS MNs were cultured without these neurotrophic factors.

Serial diluted lysates were arrayed on nitrocellulose-coated FAST slides (Whatman, Kent, UK) using the Aushon 2470 Arrayer (Aushon Biosystems, Billerica, MA). Each slide was probed with a primary antibody plus a biotin-conjugated secondary antibody. The signal was amplified using the DakoCytomation-catalyzed system (Dako, Carpinteria, CA) and visualized using a 3,3′-diaminobenzidine colorimetric reaction. The slides were scanned, analyzed, and quantified using customized Microvigene software (VigeneTech, Inc., Carlisle, MA) to measure spot intensity. Each dilution curve was fitted with the logistic model “Supercurve Fitting” (39 ). The mean values of the protein levels in the nonstimulated cells were used to normalize the time courses of the phosphorylated proteins measured in IGF-1–stimulated cells.

We selected 33 children with GHD diagnosed at Longgang District Maternity and Child Health Hospital as the disease group, and 24 healthy children of the same age as the control group. The ages of children in the two groups ranged between 5 and 14 years, with no statistical difference seen in the comparative analysis (P > 0.05) (Table 1). All the children with GHD were diagnosed at the Department of Growth and Development, Shenzhen Longgang District Maternity and Child Health Hospital. The disease group met the diagnostic criteria for GHD in Chinese children (15 ): ① Below the third percentile of the height of normal healthy children of the same age and sex (−1.88 standard deviations [−1.88 SD] or minus 2 standard deviations [−2 SD]); ② Annual growth rate <5 cm/year; ③ Symmetrical dwarfism and childish face; ④ Normal intelligence development; ⑤ Bone age lagging behind actual age; ⑥ Peak values of two GH drug provocation tests of <10 µg/L; ⑦ Lower than normal level of serum IGF-1. The exclusion criteria for children in the two groups included: ① Severe liver or gastrointestinal disorders; ② Severe infection; ③ Treatment with antibiotics or probiotic preparations within one month before the test. All children provided informed consent from their guardians before enrollment.

The ade4 package in R (v3.3.3) software was used to perform principal component analysis (PCA) based on the composition and relative abundance of bacteria in all samples at the genus level. The overall distribution of the microbiota compositions in the two groups was plotted. Bacteria were classified to the phylum and genus levels, and different species between the two groups were investigated by the Wilcoxon method where P < 0.05 indicated a significant difference. The 16S rDNA sequencing data were used to evaluate differences in bacterial functions between the two groups of children based on the functional analysis performed by the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. SPSS 22.0 software was used for general data analysis. The age, weight, height, and IGF-1 values were compared by χ2 tests or two-group independent sample t-tests.
