Abstract:
Human immunodeficiency virus type-1 (HIV-1) can either undergo a lytic pathway to cause productive systemic infections or enter a latent state in which the integrated provirus remains transcriptionally silent for decades. The ability to latently infect T-cells enables HIV-1 to establish persistent infections in resting memory CD4+ T-lymphocytes which become reactivated following the disruption or cessation of intensive drug therapy. The maintenance of viral latency occurs through epigenetic and non-epigenetic mechanisms. Epigenetic mechanisms of HIV latency regulation involve the deacetylation

The class I cyclin family is a well-studied group of structurally conserved proteins that interact with their associated cyclin-dependent kinases (Cdks) to regulate different stages of cell cycle progression depending on their oscillating expression levels.

As a classic example of a transcriptional cyclin, cyclin C forms a regulatory sub-complex with its partner kinase Cdk8 and two accessory subunits Med12 and Med13 called

Diverse classes of non-coding RNAs, including snRNAs (small nuclear RNAs), play fundamental regulatory roles in gene expression.

Abstract:
Lysosomotropic agent chloroquine was shown to sensitize non-stem glioblastoma cells to radiation in vitro with p53-dependent apoptosis implicated as one of the underlying mechanisms. The in vivo outcomes of chloroquine or its effects on glioblastoma stem cells have not been previously addressed. This study undertakes a combinatorial approach encompassing in vitro, in vivo and in silico investigations to address the relationship between chloroquine-mediated radiosensitization and p53 status in glioblastoma stem cells. Our findings reveal that chloroquine elicits antagonistic impacts on signalin

Abstract:
The phenomenon of gene silencing by small non-coding RNAs, i.e., small interfering RNA (siRNA) and microRNA (miRNA) has becoming as one of potential approaches for crop improvement. Gene silencing is generally defined as an epigenetic modification of gene expression leading to inactivation of previously active individual genes or larger chromosome regions. Gene silencing can also occur post transcriptionally due to mRNA degradation and/or repression of its translation. These effects are often mediated by small RNA regulators such as small interfering RNAS (siRNAs), microRNAs (miRNAs) which are

Abstract:
Aberrant transcriptional networks are hallmarks of aging and cancer, yet our ability to target these aberrations is poor. PU.1 is one such transcription factor (TF) who's transcriptional networks are corrupted in disease, including in >50% of Acute Myeloid Leukemia (AML) cases. In this study we investigate an unappreciated pharmacological approach to target the aberrant PU.1 network, by employing novel small molecules which competitively inhibit PU.1:DNA interactions. We performed an extensive multiomics-driven, molecular characterization of AML cells following exposure to PU.1-DNA bind

Abstract:
Reactivation of fetal cardiac genes, including those encoding atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), is a key feature of pathological cardiac remodeling and heart failure. Intensive studies on the regulation of ANP and BNP have revealed the involvement of numerous transcriptional factors in the regulation of the fetal cardiac gene program. Among these, we identified that a transcriptional repressor, neuron-restrictive silencer factor (NRSF), also named repressor element-1-silencing transcription factor (REST), which was initially detected as a transcriptional rep

Abstract:
Transcriptional coactivators play a key role in RNA polymerase II transcription and gene regulation. One of the most important transcriptional coactivators is the Mediator (MED) complex, which is an evolutionary conserved large multiprotein complex. MED transduces the signal between DNA-bound transcriptional activators (gene-specific transcription factors) to the RNA polymerase II transcription machinery to activate transcription. It is known that MED plays an essential role in ER-mediated gene expression mainly through the MED1 subunit, since estrogen receptor (ER) can interact with MED1 by s

Background: microRNAs are small non-coding RNAs which inhibit translational and post-transcriptional processes whereas long non-coding RNAs are found to regulate both transcriptional and post-transcriptional gene expression. Medicago truncatula is a well-known model plant for studying legume biology and is also used as a forage crop. In spite of its importance in nitrogen fixation and soil fertility improvement, little information is available about Medicago non-coding RNAs that play important role in symbiosis.

Abstract The tryptophan catabolizing enzymes indoleamine-2,3-dioxygenase (IDO)1 and IDO2 play important immune modulatory roles in development of inflammation and tolerance. In contrast to the immune regulatory function described for IDO1, IDO2 is a proinflammatory modifier of disease in models of autoimmune arthritis and contact hypersensitivity. Using catalytically inactive IDO2 knock-in mice, we found that the enzymatic function of IDO2 was required to mediate inflammation in contact hypersensitivity but was not required for the development of autoimmunity, suggesting IDO2 acts through both

Abstract The presented research is relevant, as breast cancer is the most commonly diagnosed cancer in the female population worldwide, with the exception of skin cancer. The aim of this article is to study the transcription phenotype of circulating tumor cells in non-metastatic breast cancer. The transcriptional phenotype of circulating tumor cells (CTCs) was studied using real-time polymerase chain reaction (PCR). Three-year OS was 79.2, and 90.8 without the expression with p Log-Rank = 0.04. Independent prognostic factors for the recurrence of disease include the presence of CTCs expressing

Abstract:
Transcriptional enhancers are major genomic elements that control gene activity in eukaryotes. Recent studies provided deeper insight into the temporal and spatial organization of transcription in the nucleus, the role of non-coding RNAs in the process, and the epigenetic control of gene expression. Thus, multiple molecular details of enhancer functioning were revealed. Here, we describe the recent data and models of molecular organization of enhancer-driven transcription.
