“…Humanin is a mitochondrial‐derived 24‐amino‐acid peptide encoded in the mitochondrial genome by the 16S ribosomal RNA gene MT‐RNR2 (Hashimoto et al ., ). Evidence suggests that humanin is secreted and expressed in multiple tissues including the brain (Hashimoto et al ., ; Matsuoka, ), retinal pigment epithelium (Minasyan et al ., ; Nashine et al ., ), blood vessels (Bachar et al ., ; Muzumdar et al ., ), pancreatic beta cells (Hoang et al ., ), tumors (Gottardo et al ., ; Omar et al ., ), and testes (Colon et al ., ; Lue et al ., ), and is also present in serum (Widmer et al ., ; Lee et al ., ; Yen et al ., ). Humanin has been demonstrated to have neuroprotective, anti‐inflammatory, antiapoptotic, antiaging, and antifibrilogenic properties through interaction with a series of targets including BAX (Guo et al ., ; Luciano et al ., ; Zhai et al ., ), insulin‐like growth factor binding protein 3 (IGFBP3) (Ikonen et al ., ), and a tripartite receptor composed of gp130, WSX1, and CNTFR (Hashimoto et al ., ).…”
