Analysis of the association of the polymorphism of the CLIC1, MSH5, C6orf26, C6orf25 genes with the expression level of the HSPA1B gene

Heat shock proteins (HSP, heat shock proteins) form one of the cellular molecular systems with chaperone activity, aimed at stabilizing the structure of intracellular proteins, ensuring the resistance of cells to stress, renaturation of incorrectly folded and elimination of denatured intrace...
