Extended Data Fig. 4. KL cells show lower basal levels of UPR-ER stress than K cells.
a, Relative intensity of O-GlcNAcylation to loading control in H2122 cells; O-GlcNAcylation signal was derived from the bracketed region of the blot in Fig. 3d. b, Doubling time of LKB1-proficient and -deficient Calu-1 cells (n=9). c, Left, Abundance of BiP protein in K and KL cell lines. Actin is used as a loading control. Right, Relative intensity of BiP to loading control in K and KL cells. Statistical significance was assessed using two sample unequal variance Student’s t-tests. *p<0.05. Cell counting for doubling time calculation was performed more than three times and Western blot was repeated twice.
