6. Regulation of Human Mitochondrial DNA Replication and Transcription
Abstract : Mitochondria are organelles in eukaryotic cells, which through oxidative phosphorylation (OXPHOS) produce most of the ATP used to drive cellular processes. The organelle contains its own genetic material, mitochondrial DNA (mtDNA), which encodes 13 key components of the OXPHOS machinery. READ MORE

7. Epigenetic Regulation of Gene Transcription in Hematopoietic Tumors
Abstract : Epigenetic modifications were shown to play an essential role in tumorigenesis. Epigenetic mechanisms can alter transcription in several ways, through DNA methylation and/or through histone modification. DNA methylation at the TSS (transcriptional start site) has been implicated in tumor development and gene silencing. READ MORE

8. Exploring and predicting DNA template dependent variation in transcription
Abstract : Reliable transmission of information from DNA to proteins is a pre-requisite for all life, where substitution errors in the polypeptide chain may arise from transcription, aminoacylation of tRNAs or translation. The fidelity control mechanisms in transcription have nevertheless received little attention, based on the assumption that the transcriptional error is masked by the translational error. READ MORE

9. Structure-function relationships of the human Runx1 transcription factor
Abstract : Runx transcription factors contain a DNA-binding andtransactivating α-subunit and a β-subunit (CBFβ)that serves to increase the DNA binding affinity of theα-subunit. The DNA binding domain of Runx proteins isnamed the Runt homology domain (RD) after its strong sequencehomology to theDrosophilaprotein Runt. READ MORE

10. Viral Strategies to Regulate Transcription and Pre-mRNA Splicing
Abstract : A typical DNA virus encodes for a few key regulatory proteins that modify the host cell biosynthetic machinery to achieve a selective viral gene statement. One such example is illustrated by the adenovirus E4-ORF4 protein, which form an enzymatically active complex with the serine and threonine-specific protein phosphatase 2A (PP2A). READ MORE
