Analysis of variants induced by combined ex vivo irradiation and in vivo tumorigenesis suggests a role for the ZNF831 p.R1393Q mutation in cutaneous melanoma development.

Ultraviolet (UV) radiation is known to be the most important environmental carcinogen for cutaneous melanoma. While genomic analyses of melanoma tumors implicate a high rate of UV damage, the experimental induction and recovery of bona fide UV-signature changes have not been directly observed. To replicate recurrent UV mutations from TCGA_SKCM specimens, we UV-irradiated cultured immortalized human melanocytes and subjected them to in vivo tumorigenesis assays.

In Vitro and In Vivo Antitumor Activities of Isothiourea and Cinnamic Acid Derivative with NOS/MCT Inhibitory Effect.

This work presents the method of synthesis and physicochemical characterization of isothiourea and cinnamic acid original derivative α-cyano-4-hydroxycinnamate 1-cyclohexanoy-l-2-ethylisothiourea (T1114). In studies of the cytotoxic and antitumor activity of T1114, it has been found that the combination in one molecular structure of NOS-inhibitory fragment (1-cyclohexanoyl-2-ethylisothiourea) and a fragment inhibiting monocarboxylate lactate transporters (MCT) (α-cyano-4-hydroxycinnamic acid) does not modify the cytotoxic activity of bifunctional NOS/MCT-inhibitor T1114 in vitro. But in vivo inhibition of NOS and MCT is able to realize effects on the tumor microenvironment and hypoxic tumor cells.
