In 2014 Western Africa experienced an unanticipated explosion of infections with Ebola virus (EBOV). What distinguishes fatal from non-fatal outcomes remains largely unknown, yet is key to optimising personalised treatment strategies. Here transcriptome data for peripheral blood taken from infected and convalescent, recovering patients, was used to identify early stage host factors that were associated with acutely ill patients that ultimately either survived or succumbed to the disease.

View SamplesThe proinflammatory cytokine, TNFalpha is critical in maintaining liver homeostasis since it is a major determiner of hepatocyte life and death. Considering this, gene transcription profiling was examined in control and TNFalpha treated HepG2 cells. Results indicated that TNFalpha could significantly alter the expression of a significant number of genes; most of them were functionally distributed among molecular functions like catalytic activity, binding, molecular transducer activity, transporter activity, translation and transcription regulator activities or enzyme regulator activity. Also, within genes up-regulated by TNFalpha, several GO terms related to lipid and fat metabolism were significantly overrepresented indicating global dysregulation of fat metabolism within the hepatocyte and those within the down-regulated dataset included genes involved in immunoglobulin receptor activity and IgE binding thereby indicating a compromise in immune defense mechanism(s) apart from those involved the DNA binding and protein binding categories. The interacting network of lipid metabolism, small molecule biochemistry was derived to be significantly affected that correlated well with the top canonical pathway of biosynthesis of steroids and molecular and cellular function of lipid metabolism. All these indicate TNFalpha to be significantly altering the transcriptome profiling within HepG2 cells with genes involved in lipid and steroid metabolism being the most favoured. This study suitably addresses the genes that determine TNFalpha mediated alterations within the hepatocyte mainly the phenotypes of hepatic steatosis and fatty liver that are associated with several hepatic pathological states.
Gene expression profiling and network analysis reveals lipid and steroid metabolism to be the most favored by TNFalpha in HepG2 cells.

View SamplesExtrapulmonary manifestations constitute 15-20% of tuberculosis cases, with lymph node as the most common site. Understanding of disease etiology is limited due to the lack of understanding patients infected tissue milieu. This study was designed to perform global transcriptome analysis of lymph node tissues from healthy individuals and Mycobacterium tuberculosis infected lymph nodes of patients to decipher the local response of infected tissue.

View SamplesThe heat-shock stress response was studied at the level of exons using Affymetrix Exon-array profiling for both sense and anti-sense transcripts. Sense transcript profiling was done as per the protocol of Affymetrix Exon 1.0 ST array and anti-sense transcript array profiling was done using a modified protocol (Xijin Ge et al., BMC Genomics. 2008 Jan 22;9:27).
