The BCL2 gene, short for B-cell lymphoma 2, is a critical regulator of apoptosis, or programmed cell death. It belongs to a larger BCL2 gene family, which includes both pro-apoptotic and anti-apoptotic proteins that maintain a delicate balance between cell survival and cell death. Dysregulation of this gene family is implicated in a variety of diseases, most notably cancer. What is BCL2? The ...
Oxidative phosphorylation is the process by which mitochondria produce ATP (adenosine triphosphate) in the cellular respiration chain. It is a crucial step in cellular energy metabolism. In this process, electrons are transferred from one carrier to another through a series of oxidation-reduction reactions and are ultimately passed to oxygen to form water. The energy released by this electron ...
Introduction Cellular mechanisms driving cell death play a crucial role in various physiological and pathological processes. One such mechanism is apoptosis, a tightly regulated process vital for maintaining tissue homeostasis, development, and immune response. Apoptosis assays are valuable tools used by researchers to study the intricate details of this cellular event. This blog aims to ...
Overview of Cytochrome P450 Cytochrome P450 (CYP450), is a family of hemoglobin-coupled monooxygenases. In mammals, CYP450 oxidizes steroids, fatty acids, and xenobiotics, playing an important role in the metabolism of various compounds as well as in the synthesis and breakdown of hormones. In plants, they regulate the synthesis of defense compounds, fatty acids, and hormones. With the progress ...
Mitochondria play a key role in maintaining cellular health and viability, and their dysfunction not only contributes to the development of many human diseases such as neurodegenerative diseases, cardiovascular diseases, obesity and type II diabetes, but also reduces oocyte quality and early embryonic development in animals. Mitochondrial function is dependent on ...
Fatty acids, along with glucose and amino acids, are the main source of energy for cell growth and proliferation. Abnormalities in fatty acid metabolism are commonly seen in cancer. A growing number of studies have shown that increased ab initio synthesis of fatty acids in tumor cells is a prominent feature in the development of cancer. And the activation of ab initio synthesis is negatively ...
Cadmium (Cd) may pose risks to freshwater organisms, including crabs that live at the interface of sediments and water column all year round. One of the major changes that occur during oocyte maturation of crabs is the production of vitellin (Vn). In the present study, we investigated the effects of Cd on oocyte size, Vn level, and vitellogenin (Vg) mRNA expression in the ovary of the ...
We describe phylogenetic and functional studies of three septins in the free-living ciliate Tetrahymena thermophila. Both deletion and overproduction of septins led to vacuolization of mitochondria, destabilization of the nuclear envelope, and increased autophagy. All three green fluorescent protein-tagged septins localized to mitochondria. Specific septins localized to the outer mitochondrial ...
The twin-Cx9C motif protein Pet191 is essential for cytochrome c oxidase maturation. The motif Cys residues are functionally important and appear to be present in disulfide linkages within a large oligomeric complex associated with the mitochondrial inner membrane. The import of Pet191 differs from that of other twin-Cx9C motif class of proteins in being independent of the Mia40 ...
