Target Data

Function Binds directly to activin and functions as an activin antagonist. Specific inhibitor of the biosynthesis and secretion of pituitary follicle stimulating hormone (FSH).
Gene References into Functions
  1. These data suggest that activin-follistatin regulation may play a role during the development of Experimental autoimmune epididymo-orchitis. PMID: 28205525
  2. Uterine Fst-cKO mice demonstrate severe fertility defects and deliver only 2% of the number of pups delivered by control females. In Fst-cKO mice, the uterine luminal epithelium does not respond properly to estrogen and progesterone signals and remains unreceptive to embryo attachment by continuing to proliferate and failing to differentiate. PMID: 28559342
  3. Data suggest that the level of circulating follistatin is involved in testicular damage due to autoimmune orchitis; these studies were conducted using gene transfer to increase circulating levels of follistatin in experimental model of autoimmune orchitis. PMID: 28667125
  4. Surface plasmon resonance analysis showed no significant association between FS288 and AMHC , suggesting that FS288 indirectly regulates AMH signaling. Activin A, a direct target of FS288, did not itself induce reporter activity in P19 cells, but did prevent the FS288-induced increase in AMH signaling. Hence, local concentrations of FS288 and Activin A may influence the response of some cell types to AMH. PMID: 28500669
  5. Hypergravity affects follistatin levels in muscle through the vestibular system in mice. Follistatin may play some roles in the interactions between muscle and bone metabolism in response to gravity change. PMID: 28471505
  6. Fst promotes brown adipocyte characteristics in both white adipose tissue and brown adipose tissue depots in vivo through distinct mechanisms. PMID: 28324027
  7. Results showed activin-C and follistatin are differentially expressed during prostate development and suggested that the antagonistic property of follistatin is secondary to the action of activin-C. Study provides evidence to support a role of activin-C in prostate development and provides new insights in the spatiotemporal localization of activins and their antagonists during mouse prostate development. PMID: 28363632
  8. Oviducts of tghFST315 mice failed to coil, the myometrium was disorganised, endometrial gland number was reduced and oviducts and uteri contained abundant leukocytes. These studies show that follistatin is crucial to postnatal oviductal-uterine development and function. PMID: 24630125
  9. OVOL1-regulated Fst and SFRP1 affect hair inductive potency of neonatal dermal cells. PMID: 25827793
  10. This study assesses the regulation of activin A and follistatin in a murine myocardial ischaemia-reperfusion model. PMID: 25052838
  11. Results implicate a role of follistatin (Fst) in the induction of brown adipocyte character and regulation of energy metabolism. PMID: 24443561
  12. follistatin induces hair wave propagation and its level decreases in aging mice. PMID: 24618599
  13. Follistatin aids in maintaining proper somite size, and consequently sclerotome progenitor numbers, by preventing paraxial mesoderm from adopting an intermediate/lateral plate mesodermal fate in the Noggin-deficient state. PMID: 24514266
  14. Report role of activin A-myostatin-follistatin system on aging bone and muscle progenitor cells. PMID: 23178301
  15. Although it is a promising therapeutic tool in chronic or acute inflammatory conditions not caused by virulent pathogens, FS does not seem to increase the resistance to bacterial infections. PMID: 23143061
  16. Data from transgenic mice suggest that overexpression of follistatin negatively influences bone metabolism decreasing all measured biomechanical strength parameters in developing bone. PMID: 22311089
  17. These data indicate that the rapid increase in circulating activin A during LPS-induced inflammation is regulated at the posttranscriptional level. PMID: 22855279
  18. regulation of Smad3- and mTOR-dependent events by follistatin occurred independently of overexpression or knockout of myostatin, a key repressor of muscle development that can regulate Smad3 and mTOR signaling and that is itself inhibited by follistatin PMID: 22711699
  19. We conclude that testosterone stimulation of satellite cell proliferation and myogenic differentiation are associated with up regulation of Fst and inhibition of TGF-beta-signaling. PMID: 22138414
  20. follistatin stimulated myoblasts to express MyoD, Myf5, and myogenin, which are myogenic transcription factors that promote myogenic differentiation PMID: 21689628
  21. These results demonstrate that body composition and glucose homeostasis are differentially regulated by FST and FSTL3 and that their combined loss is associated with increased fat mass and insulin resistance despite elevated insulin production. PMID: 21546932
  22. gradual increase in muscle regeneration, production stimulated in the presence of necrosis PMID: 21416223
  23. the transition between stem cells and committed progenitors is neither sharp nor irreversible and GDF11, ACTbetaB and FST are crucial components of a circuit that controls both total cell number and the ratio of neuronal versus glial cells in this system PMID: 21852401
  24. Results show that FST is critical for normal regulation of germ cell nest breakdown and that loss of the FST303 and/or FST315 isoforms leads to excess primordial follicles with accelerated demise, resulting in premature cessation of ovarian function. PMID: 21106872
  25. Changes in hepatically metabolised follistatin during and after exercise are reported. PMID: 21068158
  26. Data show that follistatin mutant mice exhibit haploinsufficiency, with muscles of reduced size, a shift toward more oxidative fiber types, impairment of muscle remodeling in response to injury, and reduction in tetanic force production. PMID: 20810712
  27. link between mTOR and miRNA biogenesis; an mTOR-miR-1-HDAC4-follistatin pathway that regulates myocyte fusion during myoblast differentiation in vitro and skeletal muscle regeneration in vivo. PMID: 20566686
  28. The FST288-only isoform is sufficient for development. Loss of FST303 and FST315 isoforms results in fertility defects that resemble activin hyperactivity and premature ovarian failure. PMID: 20032047
  29. we studied the expression of follistatin in rat and mouse liver tumors as a possible mechanism to overcome activin growth control, 40% of the tumors displayed increased levels of follistatin mRNA when compared to tumor-surrounding liver tissue. PMID: 12203361
  30. up-regulation of the follistatin mRNA level in the small myotubes of the regenerating soleus as well as the down-regulation of the myostatin transcript level after denervation contribute to the differentiation process in denervated regenerating muscle. PMID: 12761853
