Fig. 2. Gene expression of glucose metabolism-related factors in BeWo cells following 24 h culture in no FBS media and 20 h of sham or insulin-like 1 growth factor (hIGF1) nanoparticle treatment.

A. Gene expression of glucose transporter SLC2A1 in − FBS − hIGF1 BeWo cells was similar to + FBS − hIGF1 BeWo cells but trended for an increase when compared to − FBS + hIGF1 BeWo cells. B. Gene expression of gluconeogenesis enzyme G6PC was increased in − FBS − hIGF1 and − FBS + hIGF1 BeWo cells compared to + FBS − hIGF1. C. PCK2 expression was increased in − FBS + hIGF1 BeWo cells compared to + FBS − hIGF1 and − FBS − hIGF1. D. FBP1 expression was increased in − FBS + hIGF1 BeWo cells compared to + FBS − hIGF1 and − FBS − hIGF1. E. Gene expression of glycolysis enzymes HK2 was similar between + FBS − hIGF1 and − FBS − hIGF1 BeWo cells but increased in − FBS + hIGF1. F. Gene expression of PFKP was similar between + FBS − hIGF1 and − FBS − hIGF1 BeWo cells but increased in − FBS + hIGF1. G. Gene expression of LDHA was similar between + FBS − hIGF1 and − FBS − hIGF1 BeWo cells but increased in − FBS + hIGF1. H. Expression of LDHB was increased in − FBS − hIGF1 and − FBS + hIGF1 BeWo cells compared to + FBS − hIGF1. I. Expression of LDHC was increased in − FBS − hIGF1 and − FBS + hIGF1 BeWo cells compared to + FBS − hIGF1.
