Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for CYP2D6 and CYP2C19 Genotypes and Dosing of Selective Serotonin Reuptake Inhibitors

Abstract: Selective serotonin reuptake inhibitors (SSRIs) are primary treatment options for major depressive and anxiety disorders. CYP2D6 and CYP2C19 polymorphisms can influence the metabolism of SSRIs, thereby affecting drug efficacy and safety. We summarize evidence from the published literature supporting these associations and provide dosing recommendations for fluvoxamine, paroxetine, citalopram, escitalopram, and sertraline based on CYP2D6 and/or CYP2C19 genotype (updates at www.pharmgkb.org).

The role of the unfolded protein response in tumour development: friend or foe?

Abstract: Having accumulated mutations that overcome cell-cycle and apoptotic checkpoints, the main obstacle to survival faced by a cancer cell is the restricted supply of nutrients and oxygen. These conditions impinge on protein folding in the endoplasmic reticulum and activate a largely cytoprotective signalling pathway called the unfolded protein response. Prolonged activation of this response can, however, terminate in apoptosis. Recent delineation of the components of this response, coupled with several clinical studies, indicate that it is uniquely poised to have a role in regulating the balance between cancer cell death, dormancy and aggressive growth, as well as altering the sensitivity of solid tumours to chemotherapeutic agents.

Subtypes of medulloblastoma have distinct developmental origins

Abstract: Medulloblastomas are the most common malignant childhood brain tumours and are thought to arise from the cerebellum. There is substantial heterogeneity among medulloblastomas and some are thought to arise following aberrant Sonic Hedgehog pathway activation. It is now shown that a distinct subtype of medulloblastoma arises from the dorsal brainstem and is associated with altered WNT signalling. Distinct molecular and clinical profiles of the subtypes have implications for future treatment.

The tumor lysis syndrome.

Abstract: The tumor lysis syndrome is the most common disease-related emergency in children and adults with hematologic cancers. This review summarizes current strategies for risk assessment, prophylaxis, and therapy.
