Adiponectin counteracts cytokine- and fatty acid-induced apoptosis in the pancreatic beta-cell line INS-1.
Rakatzi I, Mueller H, Ritzeler O, Tennagels N, Eckel J. Rakatzi I, et al. Diabetologia. 2004 Feb;47(2):249-58. doi: 10.1007/s00125-003-1293-3. Epub 2004 Jan 13. Diabetologia. 2004. PMID: 14722646
[LysB3, GluB29] insulin: a novel insulin analog with enhanced beta-cell protective action.
Rakatzi I, Seipke G, Eckel J. Rakatzi I, et al. Biochem Biophys Res Commun. 2003 Oct 24;310(3):852-9. doi: 10.1016/j.bbrc.2003.09.090. Biochem Biophys Res Commun. 2003. PMID: 14550282
We assessed IRS activation by IG and its anti-apoptotic activity against cytokines or palmitic acid in comparison to insulin, insulin analogs, and insulin-like growth factor (IGF)-I using INS-1 cells. ...

Differential phosphorylation of IRS-1 and IRS-2 by insulin and IGF-I receptors.
Rakatzi I, Stosik M, Gromke T, Siddle K, Eckel J. Rakatzi I, et al. Arch Physiol Biochem. 2006 Feb;112(1):37-47. doi: 10.1080/13813450500500332. Arch Physiol Biochem. 2006. PMID: 16754202
The specific contribution of insulin and IGF-I receptors to IRS-protein activation remains elusive. We studied the signalling properties of AspB10-insulin, an analog with enhanced affinity for the IGF-I receptor, in comparison to native insulin using primary human s …

Eicosanoids and the regulation of cardiac glucose transport.
Dransfeld O, Rakatzi I, Sasson S, Eckel J. Dransfeld O, et al. Among authors: rakatzi i. Ann N Y Acad Sci. 2002 Jun;967:208-16. doi: 10.1111/j.1749-6632.2002.tb04277.x. Ann N Y Acad Sci. 2002. PMID: 12079849
A novel insulin analog with unique properties: LysB3,GluB29 insulin induces prominent activation of insulin receptor substrate 2, but marginal phosphorylation of insulin receptor substrate 1.
Rakatzi I, Ramrath S, Ledwig D, Dransfeld O, Bartels T, Seipke G, Eckel J. Rakatzi I, et al. Diabetes. 2003 Sep;52(9):2227-38. doi: 10.2337/diabetes.52.9.2227. Diabetes. 2003. PMID: 12941761
This finding correlated with a prominent Shc/IGF-I receptor interaction, tyrosine phosphorylation of Shc, activation of extracellular signal-regulated protein kinase (ERK)-1 and -2, and stimulation of DNA synthesis by HMR 1153 and Asp(B10) insulin. ...

Insulin receptor substrate-4 is expressed in muscle tissue without acting as a substrate for the insulin receptor.
Schreyer S, Ledwig D, Rakatzi I, Klöting I, Eckel J. Schreyer S, et al. Among authors: rakatzi i. Endocrinology. 2003 Apr;144(4):1211-8. doi: 10.1210/en.2002-220723. Endocrinology. 2003. PMID: 12639902
In human skeletal muscle cells, both IRS-1 and IRS-2 are rapidly phosphorylated on tyrosine in response to insulin, whereas essentially no tyrosine phosphorylation of IRS-4 was observed in response to both insulin and IGF-I. ...Our data suggest that IRS-4 does not function …
