The proteins known as insulin-like growth factors (IGFs) share a lot of similarities with insulin in their sequence. IGFs are a component of a sophisticated system used by cells to interact with their physiologic environment. Two cell-surface receptors (IGF1R and IGF2R), two ligands (IGF-1 and IGF-2), a family of seven high-affinity IGF-binding proteins (IGFBP1 to IGFBP7), and associated IGFBP degrading enzymes, collectively known as proteases, make up this intricate system, which is frequently referred to as the IGF "axis." IGF-1 plays a role in controlling various aspects of brain development, such as neurogenesis, myelination, synaptogenesis, dendritic branching, and neuroprotection following neuronal damage. IGF-I serum levels that are greater in children have been linked to a higher IQ. IGF-1 regulates apoptosis, which influences how the cochlea develops. Hearing loss can result from its absence. Additionally, an association between low stature and impaired hearing, particularly between the ages of three and five and eighteen, is explained by the serum level of it.
IGF receptors • Cell proliferation • Proteases
Since their discovery in the late 1950s, insulin-like growth factors (IGFs) have attracted the attention of researchers in a number of domains, including endocrinology, paediatrics, growth, metabolism, nutrition, ageing, and cancer. IGF1, which was initially identified as a growth hormone activity modulator, is now believed to be involved in a variety of cellular and organismal processes. The signalling pathways activated by IGF1 have undergone extensive biochemical and molecular elucidation over the past 40 years. Fundamental questions regarding the differences between the actions of the insulin molecule and IGF1 remain unresolved, nevertheless. In this editorial, a number of new studies on the biology of cancer, ageing, and development are reviewed [1]. The publications examine the IGF1 system's scientific and clinical components, including post-genomic investigations and novel approaches to target the IGF1R in the treatment of cancer. The IGF1 axis plays a crucial role in longevity and ageing, as was already mentioned. On the other hand, little is known about the pharmacological and molecular mechanisms underpinning the link between IGF1 and ageing processes. Researchers evaluated baseline total blood IGF1, IGFBP-1, IGFBP-3, and IGF1/IGFBP-3 molar ratios as predictors of incident age-related disorders in a prospective cohort of older persons (mean age=76.1 6.8 year). They then adjusted the risks for age and sex for allcause mortality and these diseases. It was discovered that higher IGF1 levels and bioavailability could predict the risk of death and morbidity, supporting the idea that diminished GH-IGF1 signalling affects human longevity and health. IGF1 folding and secretion are dependent on the endoplasmic reticulum chaperone GRP94, which is abundantly expressed there. In the context of idiopathic short stature, researchers examined the effects of the IGF1-GRP94 connection and proposed that the chaperone mechanism might be affected by tiny medicines [2]. A novel strategy to regulate both IGF1 insufficiency and situations of excessive growth factor production may arise as a result of this molecular intervention. The relationship between IGF1 and GRP94 may also be significant in cancer. Thus, different IGF1/IGF2 interactions with GRP94 can be exploited to target medicines to particular organs. Mitochondria are significant organelles that control key processes in eukaryotic cells.
It is understood that a crucial indicator of ageing is the reduction of mitochondrial function. Scientists looked at the evidence that GH and IGF1 impact mitochondrial mass and function and contribute to specific cellular ageing processes. The authors emphasise the function of these hormones in mitochondrial biogenesis, ATP production, oxidative stress, and senescence, with an emphasis on mitochondrial illnesses as people age [3].
Recent studies indicate that the Insulin/IGF axis is crucial in the ageing process. When the gene corresponding to mammalian insulin is knocked off, nematodes, fruit flies, and other species live longer. However, it is challenging to apply this discovery to mammals since, in the smaller organism, there are numerous genes that are "insulin-like" or "IGF-1-like" (at least 37 in the nematode Caenorhabditis elegans), whereas in mammals, insulin-like proteins only have seven members (insulin, IGFs, relaxins, EPIL, and relaxin-like factor). Because humans have numerous insulin-receptor-like proteins, the roles of the human insulin-like genes appear to be distinct, with some but less interaction. Less complex creatures often have fewer receptors; for instance, the nematode C. elegans only has one insulin-like receptor [4,5].
The Islets of Langerhans, which detect insulin in response to glucose balance, are one example of a specialised organ that C. elegans lacks. Additionally, IGF1 promotes dauer formation, a C. elegans larval developmental stage, which has an impact on nematode lifespan. There isn't a mammalian equivalent. Therefore, it is unclear if IGF-1 or insulin in mammals could affect ageing, while there is some evidence to suggest that dietary restriction phenomena may be connected. Other research is starting to shed light on the crucial function that IGFs play in conditions like cancer and diabetes, for example, demonstrating that IGF-1 increases the growth of both prostate and breast cancer cells. Regarding how much IGF-1 increases the chance of developing cancer, researchers are not entirely in agreement.
