Why the study?
DOG1 is overexpressed in >95% of gastrointestinal stromal tumors, motivating an evaluation of the antitumoral effects of DOG1 inhibition on GIST.
Does DOG1 inhibition reduce viability and colony formation in human GIST cell lines?
Does DOG1 inhibition reduce viability and colony formation in human GIST cell lines?
DOG1 inhibition demonstrates antitumoral effects in GIST cells in vitro, suggesting it could serve as a potential therapeutic target.
Hypothesis-generating for DOG1 inhibition in GIST; prospective studies needed before clinical consideration.
Background/Aim: DOG1 is a calcium-activated chloride channel that has gained attention as a promising drug target due to its involvement in several processes essential for tumor development and progression. DOG1 is overexpressed in >95% of gastrointestinal stromal tumors (GIST). The aim was to determine DOG1 inhibition antitumoral effects on GIST. Materials and Methods: Human GIST (GIST-T1 and GIST882) cell lines were used to study the effect of DOG1 inhibitors on chloride currents, viability, colony formation, and cell cycle. Results: CaCCinh-A01 decreased chloride currents. CaCCinh-A01 and T16inh-A01 reduced GIST cell viability and CaCCinh-A01 affected cell cycle distribution leading to G₁ cell-cycle arrest. CaCCinh-A01 also increased the sub-G₁ phase population, indicative of apoptosis, in GIST882. CaCCinh-A01 strongly reduced the colony forming ability of the cells, whereas T16inh-A01 did not. Conclusion: DOG1 inhibition has antitumoral effects in GIST cells in vitro, and could potentially serve as a target for GIST therapy.
