Abstract
Quantification in peripheral blood mononuclear cells of mRNA of drug metabolizing enzymes or drug targets could give interesting, new information in the field of pharmacogenomics and molecular mechanisms. However, for the interpretation of these data, it is necessary to know mRNA biological variations. In this review, we propose a strategy based on the production and interpretation of clinical chemistry reference values. We discuss the concept of reference values; the necessity to master pre-analytical variations of CYP and ABC transporters; the choice of the analytical methods and of the reference genes; and finally the biological variations themselves. In particular, we focus on the importance of considering homogeneity for age, sex, degree of adiposity, tobacco and alcohol intake, food habits, and drug consumption, including their inductive effects, at the phase of subject recruitment. All this information is useful to define the partition and exclusion factors to obtain mRNA reference limits.

Interaction between drugs and endocrine diseases
The introduction of highly active antiretroviral therapy accelerated studies and our understanding on the interaction between pharmacological therapies and endocrine diseases. Drugs can precipitate endocrine via different mechanisms, including direct alteration of hormone production and secretion, dysregulation of hormonal axis, effects on hormonal transport, receptor-binding, and cellular signalling. Common drug-induced ...read more
