Psychiatric disorders represent one of the most difficult diagnostic challenges, given their frequent mixed nature and intrinsic variability, as in bipolar disorders and depression. Patients misdiagnosed as depressed are often initially prescribed serotonergic antidepressants, a treatment that can exacerbate a previously unrecognized bipolar condition. Thanks to the use of the patient’s genomic profile, it is possible to recognize such risk and at the same time characterize specific genetic assets specifically associated with bipolar spectrum disorder, as well as with the individual response to the various therapeutic options. This provides the basis for molecular diagnosis and the definition of pharmacogenomic profiles, thus guiding therapeutic choices and allowing a safer and more effective use of psychotropic drugs. Here, we report the pharmacogenomics state of the art in bipolar disorders and suggest an algorithm for therapeutic regimen choice. -
Simulating the Impact of the Interplay Between Cyp2c19 Polymorphisms and Ethnicity on Response to Clopidogrel, Using Pbpk-Pd Models
SIMULATING THE IMPACT OF THE INTERPLAY BETWEEN CYP2C19 POLYMORPHISMS AND ETHNICITY ON RESPONSE TO CLOPIDOGREL, USING PBPK-PD MODELS. Manoranjenni Chetty, Khaled Abduljalil. Certara UK, Simcyp Division, Level 2-Acero, 1 Concourse Way, Sheffield, United Kingdom. Background PBPK-PD Model: Lua scripting was used within the Simcyp simulator for the PBPK-PD model. A modified indirect response turnover model6, Clopidogrel is a prodrug that produces its anticoagulant effect after with maximum platelet aggregation (MPA%) as the PD marker was used conversion to Clopi-H4, the active metabolite. Clopi-H4 binds to simulate the response to Clopi-H4. % IPA was calculated as: irreversibly to the platelet P2Y12 adenosine diphosphate (ADP) % IPA = [MPApredose – MPApostdose / MPApredose] * 100% receptor, which inhibits platelet aggregation and reduces platelet Clopi-H4 concentrations from the PBPK model were used as the input to reactivity for the platelet’s life span1. the PD model. Clopidogrel is metabolized by two major metabolic pathways. An Model Performance Verification: The PBPK model was verified by esterase-dependent pathway leads to hydrolysis of clopidogrel into comparison of the predicted and clinically observed pharmacokinetic an inactive carboxylic acid derivative (85–92%) while a cytochrome parameters.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

In some cases, there may be extensive evidence of variants that have known pharmacogenomic relevance, whereas in other cases, the summary may serve to highlight the gaps in knowledge where further study would aid the field. This summary points to the PharmGKB website to provide an interactive version that is linked to annotated publications and to related drugs, diseases, and pathways. The human CYP3A subfamily, CYP3A4, CYP3A5, CYP3A7, and CYP3A43, is one of the most versatile of the biotransformation systems that facilitate the elimination of drugs (37% of the 200 most frequently prescribed drugs in the US [1]). Together, CYP3A4 and CYP3A5 account for ~30% of hepatic cytochrome P450, and approximately half of the medications that are oxidatively metabolized by P450 are CYP3A substrates. -
Hippo and Sonic Hedgehog Signalling Pathway Modulation of Human Urothelial Tissue Homeostasis
Hippo and Sonic Hedgehog signalling pathway modulation of human urothelial tissue homeostasis Thomas Crighton PhD University of York Department of Biology November 2020 Abstract The urinary tract is lined by a barrier-forming, mitotically-quiescent urothelium, which retains the ability to regenerate following injury. Regulation of tissue homeostasis by Hippo and Sonic Hedgehog signalling has previously been implicated in various mammalian epithelia, but limited evidence exists as to their role in adult human urothelial physiology. Focussing on the Hippo pathway, the aims of this thesis were to characterise expression of said pathways in urothelium, determine what role the pathways have in regulating urothelial phenotype, and investigate whether the pathways are implicated in muscle-invasive bladder cancer (MIBC). These aims were assessed using a cell culture paradigm of Normal Human Urothelial (NHU) cells that can be manipulated in vitro to represent different differentiated phenotypes, alongside MIBC cell lines and The Cancer Genome Atlas resource. Transcriptomic analysis of NHU cells identified a significant induction of VGLL1, a poorly understood regulator of Hippo signalling, in differentiated cells. Activation of upstream transcription factors PPARγ and GATA3 and/or blockade of active EGFR/RAS/RAF/MEK/ERK signalling were identified as mechanisms which induce VGLL1 expression in NHU cells. Ectopic overexpression of VGLL1 in undifferentiated NHU cells and MIBC cell line T24 resulted in significantly reduced proliferation. Conversely, knockdown of VGLL1 in differentiated NHU cells significantly reduced barrier tightness in an unwounded state, while inhibiting regeneration and increasing cell cycle activation in scratch-wounded cultures. A signalling pathway previously observed to be inhibited by VGLL1 function, YAP/TAZ, was unaffected by VGLL1 manipulation. -

More than 50 genomic regions have been associated with MS susceptibility and vitamin D status also influences the risk of this complex disease. However, how these factors interact in disease causation is unclear. We aimed to investigate the relationship between vitamin D receptor (VDR) binding in lymphoblastoid cell lines (LCLs), chromatin states in LCLs and MS-associated genomic regions. Using the Genomic Hyperbrowser, we found that VDR-binding regions overlapped with active regulatory regions [active promoter (AP) and strong enhancer (SE)] in LCLs more than expected by chance [45.3-fold enrichment for SE (P < 2.0e205) and 63.41-fold enrichment for AP (P < 2.0e205)]. -
