(A) Cells were transfected with HMCES (H-1 and H-2), POLK, or a non-targeting siRNA (NT) and were incubated with 4-OHT before DNA combing.
(B) UGI or empty vector (EV) was introduced by lentiviral infection.
(C) Cells were transfected with HMCES or non-targeting siRNA, treated with DMSO, 4-OHT, and 10 μM JH-RE-06 for 30 min as indicated, and processed for DNA combing.
(D) Cells were transfected with HMCES and POLK siRNA, treated with 4-OHT, and processed for DNA combing. Bars represent the median, and p values were derived from an ANOVA with Dunn’s multiple comparisons post-test.
