L1, a 3,3'-diindolylmethane-derivative, induced ER stress-mediated apoptosis and suppressed growth through the FLI1/AKT pathway in erythroleukemia HEL cells.

ABSTRACT:

Introduction

3,3'-Diindolylmethane (DIM) is a major phytochemical product derived from ingestion of cruciferous vegetables. As an effective cancer chemopreventive agent, DIM has been used in preclinical and clinical trials. Recently, our group synthesized and modified a novel DIM derivative, L1, and demonstrated its significant antileukemic activities.

Methods

MTT assay was used to confirm the inhibition rates and IC₅₀ value of L1 in erythroleukemia HEL cells. Flow cytometry analysis was used to reveal cell cycle arrest and apoptosis. RNAseq data with KEGG pathway enrichment analysis was performed to predict the anticancer mechanism of L1. RT-qPCR and Western blotting were carried out to verify the mechanism in the ER stress-mediated apoptosis and FLI1/AKT pathway
