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)
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)
Analysis of G-banded prometaphase chromosomes from three XX males revealed extra bands on the distal end of one X short arm. These bands were similar both in size and staining properties to the distal Y short arm of their fathers (in the two cases examined) and also to other chromosomally normal males. The extra material on the abnormal X chromosomes was(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)
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 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)
Chronic inflammation in tumor microenvironment plays an important role at different stages of tumor development. The specific mechanisms of the association and its role in providing a survival advantage to the tumor cells are not well understood. Mitochondria are emerging as a central platform for the assembly of signaling complexes regulating inflammatory(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)
The nuclear factor κB (NF-κB) transcription factor family plays a key role in regulation of the inflammatory pathway in response to different physiological stimuli starting from development to ageing. The dysregulation of NF-κB has been associated with many pathological conditions like inflammatory diseases, neurodegeneration, metabolic diseases and various(More)
