Figure Lengend Snippet: FIGURE 4 Environment-induced heat stress altered calcium regulatory proteins in LV. In LV (a) environment-induced heat stress increased the relative protein abundance of the PLB/SERCA2a complex, STIM1, CaMKII, p-PKC pan, and p-PKC alpha/beta II compared to TN; while the monomeric and oligomeric forms of PLB, p-CaMKII, and p-PLB were similar between groups. In RV (b) relative protein abundance of the oligomeric form of PLB and p-PKC alpha/beta II increased by EIHS compared to TN; whereas the monomeric form of PLB, PLB/SERCA2a complex, STIM1, CaMKII, p-CaMKII, p-PLB, and p-PKC pan were similar between groups. Treatments: EIHS, environment-induced heat stress; TN, thermoneutral. Results are expressed as means ± standard deviation. * indicates p < 0.05. (a) LV: Monomer, oligomer, SERCA2a complex, CaMKII, p-CaMKII, p-PLB, p-PKC pan, and p-PKC alpha/beta II n = 7/group, one outlier from EIHS CaMKII and p-CaMKII and one outlier removed from TN p = PKC pan and p-PKC alpha/beta II; STIM1 n = 6/group, one outlier removed from EIHS. (b) RV: Monomer, oligomer, SERCA2a complex, CaMKII, p-CaMKII, p-PLB, n = 7/group, one outlier removed from TN oligomer; STIM1 n = 8/group, one outlier removed EIHS; p-PKC pan and p-PKC alpha/beta II TN n = 6/group, EIHS n = 8/group, one outlier removed from EIHS p-PKC alpha/beta II.
