Figure Lengend Snippet: Cellular expression of the LDLR variants. HEK293T- ldlr G1 cells transfected with pTetRedLDLR expression vectors were cultured in the medium supplemented with 100 ng/mL doxycycline for 48 h. The cell lysates were loaded onto a gel at equal total protein concentrations and analyzed by Western blot. A: The 150 kDa bands represent mature form of LDLR wild-type (WT) (line 1), c.91G > A p. (Glu31Lys) (line 2), c.662 A > G p. (Asp221Gly) (line 3), c.1775G > A p. (Gly592Glu) (line 4), c.2483delA p. (Tyr828Phefs∗101) (line 5), c.661G > T p. (Asp221Tyr) (line 6), c.1216C > T p. (Arg406Trp) (line 7), c.2177C > T p. (Thr726Ile) (line 8), Hek293T- ldlr G1 non-transfected (line 9), respectively. The 25 kDa signals represent the DsRed2 protein, indicating the correct transfection process. The 50 kDa bands demonstrate β-actin. B: LDLR signals were normalized to the intensity of DsRed2. The relative level of LDLR variants was assessed using the ratio of the variants compared to wild-type band intensity. The mean of four independent Western blots (n = 4) is shown in the graph. The green line is the 90 % threshold, and the red line is the 70 % threshold. Asterisks indicate statistically significant results in the T-test.
