Moreover, several studies have identified alterations in specific PP2A subunits in human cancers, which has led to the hypothesis that PP2A serves as a tumor suppressor [6], [7].
MRI studies with different techniques [ 38– 43] and electrophysiological investigations [ 44] on neuronal inhibition have identified alterations in brain areas of the cortico-striato-thalamo-cortical (CSTC) circuits.
In summary, we have identified alterations in key indices of tryptophan metabolism in a male IBS population which are attributable to immune activation.
Recent results have identified alterations in pathway components PIK3CA, PTEN, AKT1 and TSC1 in bladder cancer, some of which are significantly related to tumour phenotype and clinical behaviour.
Although these studies have identified alterations characteristic of the tumor vasculature per se, they have not addressed the question of vascular heterogeneity or investigated whether distinct intertumoral vascular subtypes exist.
Although we have identified alterations in regional layering and cell positioning, it remains to be seen what specific cell types are affected by reduced reelin expression and/or CPO exposure.
Several studies have identified alterations of cell cycle regulators in human breast cancer (reviewed in [ 8, 9]) and provide a rationale for a potential therapeutic role for CDK4/6 inhibition in this tumor type.
Existing studies of candidate IBD-associated genetic variants have identified alterations in the intestinal microbiome in individuals carrying polymorphisms in NOD2 and FUT2, an enzyme that fucosylates mucus glycoproteins [ 9, 10].
Chromosomal-based studies [ 14, 15] e.g., CGH and high resolution SNP arrays [ 16] and molecular profiling through exome analyses have identified alterations e.g., loss of 18q22-mer [ 17, 18] or SMAD4 LOH [ 19], that may be associated with neuroendocrine neoplasia.
