extrinsic apoptotic signaling pathway in absence of ligand [The series of molecular signals in which a signal is conveyed from the cell surface to trigger the apoptotic death of a cell. The pathway starts with withdrawal of a ligand from a cell surface receptor, and ends when the execution phase of apoptosis is triggered. For dependence receptors, absence of a ligand or withdrawal of a ligand from a receptor acts as a signal. An example of 'extrinsic apoptotic signaling pathway in absence of ligand' is withdrawal of a growth factor such as NGF, even if traditionally apoptosis induced via growth factor withdrawal has been classified as an instance of intrinsic apoptosis. See an example in PMID: 19767770. Ligands whose withdrawal or absence induce apoptosis should be annotated to GO:2001239 'regulation of extrinsic apoptotic signaling pathway in absence of ligand', rather than to the pathway term itself. Examples of gene products that may be annotated to GO:0097192 'extrinsic apoptotic signaling pathway in absence of ligand' include dependence receptors such as DCC or UNC5B, which relay lethal signals in the absence of their ligand (netrin-1). In the case of DCC and UNC5B, the signaling proceeds through the assembly of a DRAL- and TUCAN- (or NLRP1-) containing caspase-9-activating complex or by the dephosphorylation-mediated activation of death-associated protein kinase 1 (DAPK1) by UNC5B-bound protein phosphatase 2A (PP2A), respectively. DAPK1 can mediate the direct activation of executioner caspases or favor MOMP (reviewed in PMID: 21760595). Also see PMID: 21172653 (annotations to UNC5B and PR65beta, UniProt symbols O08722, PPP2R1B and P30154). GO:0097192]

lung alveolus development [The process whose specific outcome is the progression of the alveolus over time, from its formation to the mature structure. The alveolus is a sac for holding air in the lungs; formed by the terminal dilation of air passageways. GO:0048286]

lung development [The process whose specific outcome is the progression of the lung over time, from its formation to the mature structure. In all air-breathing vertebrates the lungs are developed from the ventral wall of the esophagus as a pouch which divides into two sacs. In amphibians and many reptiles the lungs retain very nearly this primitive sac-like character, but in the higher forms the connection with the esophagus becomes elongated into the windpipe and the inner walls of the sacs become more and more divided, until, in the mammals, the air spaces become minutely divided into tubes ending in small air cells, in the walls of which the blood circulates in a fine network of capillaries. In mammals the lungs are more or less divided into lobes, and each lung occupies a separate cavity in the thorax. GO:0030324]

GO:0060426]

mammary gland development [The process whose specific outcome is the progression of the mammary gland over time, from its formation to the mature structure.

retinal cell apoptotic process [Any apoptotic process in a retinal cell. GO:1990009]

signal transduction [The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.|Note that signal transduction is defined broadly to include a ligand interacting with a receptor, downstream signaling steps and a response being triggered. A change in form of the signal in every step is not necessary. Note that in many cases the end of this process is regulation of the initiation of transcription. Note that specific transcription factors may be annotated to this term, but core/general transcription machinery such as RNA polymerase should not. GO:0007165]

There are at least three mechanisms by which this is achieved. Skeletal muscle satellite stem cell asymmetric division ensures satellite stem cell numbers are kept constant. Symmetric division of these cells amplifies the number of skeletal muscle satellite stem cells. Some adult skeletal muscle myoblasts (descendants of activated satellite cells) can develop back into quiescent satellite cells, replenishing the overall pool of satellite cells. GO:0014834]

7. Gene Descriptions

NCBI Gene Summary: The protein encoded by this gene is similar to insulin in function and structure and is a member of a family of proteins involved in mediating growth and development. The encoded protein is processed from a precursor, bound by a specific receptor, and secreted. Defects in this gene are a cause of insulin-like growth factor I deficiency. Alternative splicing results in multiple transcript variants encoding different isoforms that may undergo similar processing to generate mature protein. [provided by RefSeq, Sep 2015]

GeneCards Summary: IGF1 (Insulin Like Growth Factor 1) is a Protein Coding gene. Diseases associated with IGF1 include Growth Delay Due To Insulin-Like Growth Factor Type 1 Deficiency and Insulin-Like Growth Factor I. Among its related pathways are Apoptotic Pathways in Synovial Fibroblasts and GPCR Pathway. Gene Ontology (GO) annotations related to this gene include growth factor activity and integrin binding. An important paralog of this gene is IGF2.

UniProtKB/Swiss-Prot Summary: The insulin-like growth factors, isolated from plasma, are structurally and functionally related to insulin but have a much higher growth-promoting activity. May be a physiological regulator of [1-14C]-2-deoxy-D-glucose (2DG) transport and glycogen synthesis in osteoblasts. Stimulates glucose transport in bone-derived osteoblastic (PyMS) cells and is effective at much lower concentrations than insulin, not only regarding glycogen and DNA synthesis but also with regard to enhancing glucose uptake. May play a role in synapse maturation [PMID: 21076856, PMID: 24132240]. Ca(2+)-dependent exocytosis of IGF1 is required for sensory perception of smell in the olfactory bulb. Acts as a ligand for IGF1R. Binds to the alpha subunit of IGF1R, leading to the activation of the intrinsic tyrosine kinase activity which autophosphorylates tyrosine residues in the beta subunit thus initiatiating a cascade of down-stream signaling events leading to activation of the PI3K-AKT/PKB and the Ras-MAPK pathways. Binds to integrins ITGAV:ITGB3 and ITGA6:ITGB4. Its binding to integrins and subsequent ternary complex formation with integrins and IGFR1 are essential for IGF1 signaling. Induces the phosphorylation and activation of IGFR1, MAPK3/ERK1, MAPK1/ERK2 and AKT1 [PMID: 19578119, PMID: 22351760, PMID: 23696648, PMID: 23243309].

9. Mechanistic Information

Summary

Upregulation of the IGF1 gene, which encodes Insulin Like Growth Factor 1, can be seen as a part of response to toxic substances or development of fibrosis [CS: 8]. For instance, in the context of pulmonary fibrosis, studies indicate an increased expression of IGF1 [CS: 9]. Fibrosis involves excessive tissue scarring and damage repair, and IGF1, by promoting cell growth and survival, aids in this repair process [CS: 7]. The gene's role in stimulating glucose transport and enhancing glucose uptake, as seen in osteoblasts, suggests a similar function in lung tissue [CS: 6]. This would provide the necessary energy for tissue repair and regeneration [CS: 6]. Additionally, the activation of IGF1/IGF-1R signaling pathways, as observed in bleomycin-induced fibrosis models, suggests its involvement in fibrogenesis, potentially by inducing PI3K/AKT signaling activation [CS: 8]. This pathway is critical for cell survival and proliferation, which are necessary responses to counteract the damage caused by fibrotic processes [CS: 9].

In cases of acute lung injuries, such as those induced by influenza A virus (IAV), IGF1 expression increases, exacerbating the inflammatory response [CS: 7]. While this increase intensifies inflammation, it might also be a necessary step for initiating tissue repair [CS: 6]. The activation of IGF1 receptor in these scenarios triggers signaling pathways crucial for initiating an inflammatory response, potentially a necessary precursor to healing and repair processes in the lung [CS: 6].
