Mitochondrial permeability transition is a phenomenon in which the mitochondrial permeability transition pore (PTP) abruptly opens, resulting in mitochondrial membrane potential (ΔΨm) dissipation, loss of ATP production, and cell death. Several genetic candidates have been proposed to form the PTP complex, however, the core component is unknown. We(More)
Mitochondria are one of the central regulators of many cellular processes beyond its well established role in energy metabolism. The inter-organellar crosstalk is critical for the optimal function of mitochondria. Many nuclear encoded proteins and RNA are imported to mitochondria. The translocation of small RNA (sRNA) including miRNA to mitochondria and(More)
Emerging evidences suggest that chronic inflammation is one of the major causes of tumorigenesis. The role of inflammation in regulation of breast cancer progression is not well established. Recently Mediator of IRF3 Activation (MITA) protein has been identified that regulates NF-κB and IFN pathways. Role of MITA in the context of inflammation and cancer(More)
We have discovered and characterized a compound polymorphic locus on chromosome 19, defined by an arbitrary genomic DNA segment cloned into a cosmid vector. Four different restriction fragment length polymorphisms with minor allele frequencies equal to or greater than 10% are revealed by Southern hybridization of subclones of cosmid 1-13 with TaqI, MspI,(More)
Autophagy is one of the cellular adaptive processes that provide protection against many pathological conditions like infection, cancer, neurodegeneration, and aging. Recent evidences suggest that ubiquitination plays an important role in degradation of proteins or defective organelle either through proteasome or autophagy. In this study, we describe the(More)
We studied the cellular distribution of an unusual chromosomal abnormality, an interstitial deletion of the long arm of chromosome 13, in the peripheral blood lymphocytes of two patients with acquired idiopathic sideroblastic anemia (AISA). We found no metaphases containing the 13q- abnormality in preparations of phytohemagglutinin (PHA)-stimulated(More)
TNF induced nuclear factor kappa B (NF-κB) is one of the central signaling pathways that plays a critical role in carcinogenesis and inflammatory diseases. Post-translational modification through ubiquitin plays important role in the regulation of this pathway. In the current study, we investigated the role of TRIM8, member of RING family ubiquitin ligase(More)
The cellular processes are controlled by a narrow range of mRNA and proteins levels, where small RNAs (sRNAs) known as miRNAs play a critical role. The spatial and temporal regulation of miRNA processing components and mature miRNA is emerging. The recent studies suggest that mitochondria are one of the destinations of pre as well as mature miRNAs. The role(More)
The modulation of mitochondrial functions is important for maintaining cellular homeostasis. Mitochondria essentially depend on the import of RNAs and proteins encoded by the nuclear genome. MicroRNAs encoded in the nucleus can translocate to mitochondria and target the genome, affecting mitochondrial function. Here, we analyzed the role of miR-4485 in the(More)
The emerging evidences suggest that endoplasmic (ER) stress is involved in onset of many pathological conditions like cancer and neurodegeneration. The persistent ER stress results in misfolded protein aggregates, which are degraded through the process of autophagy or lead to cell death through activation of caspases. The regulation of crosstalk of(More)
