Project description:We report the application of next generation sequencing technology for high-throughput profiling of total RNA to determine the expression of all genes expressed in human primary hepatocytes derived from three healthy (drug/tobacco/alcohol free) volunteers in response to anti-tuberculosis antibiotics, including, rifampin, rifabutin and rifapentine through comparison with gene profiles of vehicle (methanol) treated and untreated cells. We determined the response of over 22,000 genes expressed in human primary hepatocytes following rifampin, rifabutin and rifapentine treatment for 72h. We found that several drug metabolizing enzymes, including cytochrome P450 3A4 and drug transporters are differentially expressed in human primary hepatocytes in response to rifamycin antibiotics. We utilized the information generated with differential gene expression study to determine interaction of rifamyicn antibiotics with antiviral, antibacterial, antifungal agents and other drugs used to treat several ailments in tuberculosis patients. This study provides a comprehensive profiles of genes expressed in response to rifamycin antibiotics towards characterization of their drug interactions with the drugs that are combined to treat various viral, bacterial, fungal and other diseases, including cancer.

Project description:The piperazine derivatives most frequently consumed for recreational purposes are 1-benzylpiperazine (BZP), 1-(3,4-methylenedioxybenzyl)piperazine (MDBP), 1-(3-trifluoromethylphenyl)piperazine (TFMPP), and 1-(4-methoxyphenyl)piperazine (MeOPP). Currently it is unclear whether piperazine designer drugs induce mechanisms of hepatotoxicity and, if so, whether they act by a common mechanism. We performed a gene array study with rat hepatocytes incubated with the four designer drugs for 24 h in order to detail the global programme of gene expression Primary rat hepatocytes were cultured in collagen sandwich and incubated with the piperazine designer drugs. After 24 h, the RNA was extracted and the Affymetrix microarray analysis was performed.

Project description:Rifampin causes drug interactions by altering hepatic drug metabolism. Because microRNAs (miRNAs) have been shown to regulate genes involved in drug metabolism, we determined the effect of rifampin on the expression of hepatic miRNAs. Primary human hepatocytes from seven subjects were treated with rifampin, and the expression of miRNA and cytochrome P450 (P450) mRNAs was measured by TaqMan assays and RNA-seq, respectively. Rifampin induced the expression of 10 clinically important and 13 additional P450 genes and repressed the expression of 9 other P450 genes (P < 0.05). Rifampin induced the expression of 33 miRNAs and repressed the expression of 35 miRNAs (P < 0.05). Several of these changes were highly negatively correlated with the rifampin-induced changes in the expression of their predicted target P450 mRNAs, supporting the possibility of miRNA-induced regulation of P450 mRNA expression. In addition, several other miRNA changes were positively correlated with the changes in P450 mRNA expression, suggesting similar regulatory mechanisms. Despite the interindividual variability in the rifampin effects on miRNA expression, principal components analysis clearly separated the rifampin-treated samples from the controls. In conclusion, rifampin treatment alters miRNA expression patterns in human hepatocytes, and some of the changes were correlated with the rifampin-induced changes in expression of the P450 mRNAs they are predicted to target. Primary human hepatocytes were treated rifampin or vehicle for 24 hours. Rifampin-treated samples are not available for the 30Jul10 patient or the Hep2 patient due to raw data file corruption.

Project description:Various aspects of physiology and cell function present self-sustained ~24h variations termed circadian rhythms, enabling anticipation and adaptation to the 24-h cycle produced by the Earth’s rotation. The circadian clock system consists of a central clock located in the suprachiasmatic nucleus in the hypothalamus, and peripheral clocks present in distinct tissues. In particular, peripheral clocks in the liver have fundamental roles in maintaining liver homeostasis. Here, we established and characterized a human hepatocyte in vitro system in which human primary hepatocytes displayed self-sustained oscillations independently of external cues a distinguishing feature of circadian clocks. We then used this experimental system to study the impact of circadian oscillations in human liver pathophysiology. By generating hepatocyte circadian transcriptomes, we demonstrated that the transcriptional state of cultured human hepatocytes is dynamic across 24h. Analyses of gene expression data identified a set of cycling genes, including a subset of well-established ‘core clock genes’ and oscillating genes related to inflammation, drug metabolism, and energy homeostasis. We documented a circadian-dependent induction of the pro-inflammatory cytokines IL-1b, IL-6, TNF-a CXCLl1 and CXCL10 triggered by LPS or IFN-b in human hepatocytes. We also demonstrated circadian fluctuations of a subset of drug metabolism enzymes, which regulate drug pharmacokinetics. Among these enzymes, we identified CYP3A4, as one displaying circadian fluctuations at activity levels and a time-dependent induction with rifampin. Finally, we showed the impact of applying chronopharmacotherapy by designing a treatment protocol to minimize atorvastatin and acetaminophen induced hepatotoxicity. Collectively, our findings document that circadian time can influence the magnitude of the inflammatory response in the liver and the efficacy, toxicity, and/or the therapeutic index of drugs.

Project description:Mycobacterium tuberculosis (Mtb), although primarily a pulmonary pathogen, can disseminate to various other organs of the body causing extra pulmonary tuberculosis (EPTB). In the present study, we have shown that hepatocytes, the major parenchyma cells of the liver, get robustly infected by Mtb. Using a combination of in-vitro, ex-vivo and animal models; we demonstrate that Mtb utilizes hepatocytes as a replicative niche, modulates its various biological functions like lipid metabolism and shields itself against the common anti-TB drugs. Hepatocytes, being a key cell type having both immune and metabolic functions, controls and coordinates various aspects of the physiology in both health and disease. In case of a multifactorial chronic infection like TB, we are curious to know whether hepatocyte infection plays any major role in the systemic outcome of this age-old disease.
