Knockdown of PINK1 suppressed mitophagy and reduced the cytoprotective effect of IPC (Livingston et al., 2019)
Ile 12 Using cryo-electron microscopy, Zhang et al found that a cluster of neighboring serines (Ser 14 , Ser 17 , and Ser 18 of GLP-1) form polar interactions with Thr 298 , the backbone oxygen of Trp 297 , and the nitrogen of Arg 299 in GLP-1R.12 However, Ala mutations at any of these positions hardly affected activity.25,29 In contrast, if GLP-1R Thr 298 was mutated into Ala, it increased affinity to the ligand.30 Keliher et al ran a series of modifications of Lys 12 in exenatide, indicating that this position is not important for interactions with GLP-1R and that it is, to some extent, tolerant of bigger groups.31 The mutation of GIP Ile 12 to Ala caused a notable decrease in its insulinotropic effect.27 Hence, using Ile 12 in tirzepatide seems not to weaken its GLP-1 activity and to strengthen its GIP activity

The American Diabetes Association (ADA) recommends at least 150 minutes of moderate-intensity aerobic activity weekly, spread over at least three days, with no more than two consecutive days without activity
