As they reported today in Nature Cell Biology, the researchers found that genes with high variation in DNA methylation tended to be distinct from those with high variation in chromatin accessibility. They also observed a feedback mechanism between ...

Fat cell filling, ketogenic diet, and the history of biochemistry - EurekAlert (press release)


EurekAlert (press release)
There's more than one type of fat cell. Besides the white fat that stores triglycerides in lipid droplets in preparation for lean times later, mammals also have heat-generating brown fat, which acts more like a radiator than a storage closet. Brown fat ...

Cell Cycle - Tocris Bioscience

Bristol - United Kingdom

The cell cycle is the regulatory network that controls the order and timing of cellular proliferation events. It is divided into four stages, G1-S-G2-M. The G1 and G2 stages stands for 'GAP 1' and 'GAP 2' respectively. The S stage stands for 'Synthesis' and is the stage when DNA replication occurs. The M stage stands for 'mitosis', and is when nuclear and cytoplasmic division occurs, halving the genome.

Tocris Bioscience: Signal Transduction
United Kingdom

Signal transduction (also known as cell signaling) is the transmission of molecular signals from a cell's exterior to its interior. Signals received by cells must be transmitted effectively into the cell to ensure an appropriate response. This step is initiated by cell-surface receptors.

Tocris Bioscience - Cardiovascular Research

The cardiovascular, or circulatory, system is a closed elastic circuit consisting of the heart, blood vessels (arteries, capillaries and veins) and the blood. The primary function is to pump oxygenated blood to the tissues throughout the body and reabsorb waste carbon dioxide for its removal. This function is performed by the use of pulmonary and systemic circulation.

Cell Cycle Info
Canada

The cell cycle refers to the events that take place in a cell between its inception and subsequent replication. The cell cycle is composed of 4 distinct phases: G1 phase, S phase, G2 phase, and M phase. Interphase is a collective term that describes the G1, S, and G2 phases. During interphase, the cell is growing and preparing for mitosis (M phase) by accumulating nutrients and replicating DNA. The M phase is composed of 2 coupled processes calle

The Stages of the Cell Cycle
United States

The stages of cell division (G1, S, G2. mitosis) are described and illustrated with an animation of the cell cycle: - G1 and G2 stand for 'gaps'. This refers to the fact that nothing very obvious is occurring in the nucleus of the cells during these stages. The cells are actually very active. They are growing and preparing to divide. - S stands for synthesis. This is the phase of the cell cycle in which the DNA is copied or replicated. - M s
