In addition, there are typographical errors in the following references:

In reference [17], “α” incorrectly appears as “[agr].” The correct reference is: The reference is: Boström P, Wu J, Jedrychowski MP, Korde A, Ye L, Lo JC, et al. A PGC1-α-dependent myokine that drives brown-fat-like development of white fat and thermogenesis. Nature. 2012;481(7382):463–8.

In reference [19], “SAT-123” incorrectly appears as “SAT-123-SAT-.” The correct reference is: Triantafyllou GA, Skouvaklidou EC, Saridakis ZG, Kynigopoulos G, Dima DI, Apostolou A, et al. Circulating Follistatin and Irisin in Young, Healthy Individuals: A One-Year Prospective Cohort Study. GPCRs, Growth Factors, Tyrosine Kinases, Inhibits, Activins, and TGF Beta Superfamily (posters): Endocrine Society; 2016. p. SAT-123.

In reference [25], “brown-fat-like development” incorrectly appears as “browning.” The correct reference is: Boström P, Wu J, Jedrychowski MP, Korde A, Ye L, Lo JC, et al. A PGC1-α-dependent myokine that drives brown-fat-like development of white fat and thermogenesis. Nature. 2012;481(7382):463–8.

Reference [33] contains multiple errors. “Boström” incorrectly appears as “Bostrã M.” “PGC1-α-dependent” should appear as “PGC1-α-dependent.” The correct reference is: Boström P, Wu J, Jedrychowski MP, Korde A, Ye L, Lo JC, et al. A PGC1-α-dependent myokine that drives brown-fat-like development of white fat and thermogenesis. Nature. 2012;481(7382):463–8.

In reference [35], “ofin vitroandin vivobrown” should appear as “of in vitro and in vivo brown.” The correct reference is: Braga M, Pervin S, Norris K, Bhasin S, Singh R. Inhibition of in vitro and in vivo brown fat differentiation program by myostatin. Obesity. 2013;21(6):1180–8.
