(A) H460 cells stably transfected with pCMV or a vector encoding the
ESR1 gene were assessed for their sensitivity to NK-mediated lysis.
(B) Immunofluorescent analysis of ESR1 expression (pink signal)
in single cell clones of H460 cells with High vs. Low ESR1 expression. Blue
signal corresponds to DAPI staining. (C) Clones were evaluated for
their susceptibility to lysis by TRAIL (C) or NK cells that were
either untreated or pre-treated with CMA to inhibit perforin-dependent lytic
pathways (D). (E) Relative expression of indicated
mRNA in clonal H460 ESR1-High vs. ESR1-Low cells. (F) ESR1 and
(G) ESR2 mRNA in normal lung vs. lung adenocarcinoma (LUAD)
tissues. Shaded areas correspond to the normal range of expression for each
gene, calculated as the mean expression in normal lung tissues (± two
standard deviations). (H) mRNA expression of indicated genes in
lung samples categorized as either ESR1 Low or High, based on the expression in
normal lung tissues. Error bars indicate the standard deviation of the mean.
