LDHA and neoplasm: Glycolic rates in tumor cells could be elevated by anincreased level of lactate dehydrogenase isoform A (LDH-A)[2, 3].Thus, selective inhibition of LDH-A can arrest ATP production and promote tumorcell death [4-6].Another point to bear in mind is distinguishing betweenLDH-A and LDH-B (heart muscle LDH) that exhibit high structural similarity[7].
