  • Title: α-Cyano-4-hydroxycinnamate induces apoptosis in Dalton's lymphoma cells: role of altered cell survival-regulatory mechanisms.
    Author: Kumar A, Kant S, Singh SM.
    Journal: Anticancer Drugs; 2013 Feb; 24(2):158-71. PubMed ID: 22932131.
    Abstract:
    In the present investigation, we explored the molecular mechanisms of the tumoricidal action of α-cyano-4-hydroxycinnamate (αCHC) on the cells of Dalton's lymphoma (DL), which is a murine T cell lymphoma. In-vitro treatment of the DL cells with αCHC resulted in the modulation of the biophysical parameters of the tumor cell culture medium with respect to pH, nitric oxide, glucose, and lactate, accompanied by an alteration in the expression of cytokines (IL-10, IL-6, and IFN-γ) and cell survival-regulatory proteins such as Bcl2, p53, caspase-3, caspase-activated DNase, HSP70, and IL2R. The expression of the pH-regulatory proteins vacuolar ATPase and MCT1 was also found to be altered. The study discusses the possible role of the aforementioned alterations triggered by αCHC in the induction of tumor cell apoptosis and decreased cell survival. These findings will provide a new insight into the novel molecular mechanisms of the antitumor action of αCHC.
