ZNF133 is associated with infliximab responsiveness in patients with inflammatory bowel diseases.

Background And Aim: Infliximab has been widely prescribed for treating inflammatory bowel disease (IBD). However, the response rates to infliximab differ among patients. Therefore, we aimed to identify the genetic and clinical markers that predict infliximab response.

Influence of Polymorphism on the Pharmacokinetic/Pharmacodynamic Characteristics of Carvedilol in Healthy Korean Volunteers.

Background: Carvedilol is commonly used to treat hypertension as a β- and α-adrenoreceptor blocker, but it is metabolized by and allele is dominant in Asian population. The objective of this study was to assess the influence of polymorphisms on the pharmacokinetic (PK) and pharmacodynamic (PD) characteristics of carvedilol in healthy Korean volunteers.

Methods: A PK/PD study for a single and multiple dosing of carvedilol were conducted.

Effects of CYP2C19 Genetic Polymorphisms on PK/PD Responses of Omeprazole in Korean Healthy Volunteers.

The aim of this study was to examine the effects of CYP2C19*2 and *3 genetic polymorphisms on omeprazole pharmacokinetic (PK) and pharmacodynamic (PD) responses. Twenty-four healthy Korean volunteers were enrolled and given 20 mg omeprazole orally once daily for 8 days. The genotypes of CYP2C19 single nucleotide polymorphisms (SNPs) (*2, *3, and *17) were screened.

The influences of SLCO1B1 and ABCB1 genotypes on the pharmacokinetics of simvastatin, in relation to CYP3A4 inhibition.

Aim: To investigate the combined effects of SLCO1B1 and ABCB1 genotypes on the pharmacokinetics of simvastatin and its active metabolite simvastatin acid, in relation to CYP3A4 inhibition.

Methods: We conducted a single-dose pharmacokinetic study of simvastatin in 26 healthy volunteers screened for their SLCO1B1 c.521T>C and ABCB1 c.

Current status and regulatory perspective of chimeric antigen receptor-modified T cell therapeutics.

Chimeric antigen receptor-modified T cells (CAR-T) have emerged as a new modality for cancer immunotherapy due to their potent efficacy against terminal cancers. CAR-Ts are reported to exert higher efficacy than monoclonal antibodies and antibody-drug conjugates, and act via mechanisms distinct from T cell receptor-engineered T cells. These cells are constructed by transducing genes encoding fusion proteins of cancer antigen-recognizing single-chain Fv linked to intracellular signaling domains of T cell receptors.

Well-defined differentiation of hESC-derived hemangioblasts by embryoid body formation without enzymatic treatment.

Human hemangioblasts exist only during the early embryonic developmental stage thereby limiting the adult cellular source from which to obtain such cells for study. To overcome this, hemangioblast studies have focused on utilizing human embryonic stem cell (hESC) derivatives but current methods are cell-line dependent. Single cell dissociation of a hESC colony quickly led to cell death in most hESC lines due to enzyme treatment which, in turn, reduced induction potential and hemangioblast differentiation efficiency.

High content screening for compounds that induce early stages of human embryonic stem cell differentiation.

Embryonic stem cells, due to their self-renewal and pluripotency properties, can be used to repair damaged tissues and as an unlimited source of differentiated cells. Although stem cells represent an important opportunity for cell based therapy and small molecules screening (in the context of drug or target discovery) many drawbacks are still preventing their widespread use. One of the most significant limitations is related to the complexity, as well as the reliability, of current protocols driving stem cells into any homogeneously differentiated cellular population.
