Liquorice or licorice is the root of Glycyrrhiza glabra from which a sweet flavour can be extracted. The liquorice plant is a herbaceous perennial legume native to the Middle East, southern Europe, and parts of Asia, such as India and Nepal. It is not botanically related to anise, star anise, or fennel, which are sources of similar flavouring compounds. Liquorice flavours are used as candies or sweeteners, particularly in some European and Middle Eastern countries.
George Emil Palade ForMemRS HonFRMS was a Romanian-American cell biologist. Described as "the most influential cell biologist ever", in 1974 he was awarded the Nobel Prize in Physiology and Medicine along with Albert Claude and Christian de Duve. The prize was granted for his innovations in electron microscopy and cell fractionation which together laid the foundations of modern molecular cell biology, the most notable discovery being the ribosomes of the endoplasmic reticulum – which he first described in 1955.
Aromatase, also called estrogen synthetase or estrogen synthase, is an enzyme responsible for a key step in the biosynthesis of estrogens. It is CYP19A1, a member of the cytochrome P450 superfamily, which are monooxygenases that catalyze many reactions involved in steroidogenesis. In particular, aromatase is responsible for the aromatization of androgens into estrogens. The enzyme aromatase can be found in many tissues including gonads, brain, adipose tissue, placenta, blood vessels, skin, and bone, as well as in tissue of endometriosis, uterine fibroids, breast cancer, and endometrial cancer. It is an important factor in sexual development.
Isoliquiritigenin is a phenolic chemical compound found in licorice.
The low-affinity nerve growth factor receptor is one of the two receptor types for the neurotrophins, a family of protein growth factors that stimulate neuronal cells to survive and differentiate. LNGFR is a member of the tumor necrosis factor receptor superfamily – indeed, LNGFR was the first member of this large family of receptors to be characterized.
Harry B. Demopoulos is a researcher in the medical aspects of free radicals, especially in the areas of ischaemic injury, the toxicity of anticancer drugs, and in spinal cord injury. He has also been a film actor and is currently a member of the Board of Trustees of the Doris Duke Charitable Foundation.
Exosomes are membrane bound extracellular vesicles (EVs) that are produced in the endosomal compartment of most eukaryotic cells. The multivesicular body (MVB) is an endosome defined by intraluminal vesicles (ILVs) that bud inward into the endosomal lumen. If the MVB fuses with the cell surface, these ILVs are released as exosomes. In multicellular organisms, exosomes and other EVs are present in tissues and can also be found in biological fluids including blood, urine, and cerebrospinal fluid. They are also released in vitro by cultured cells into their growth medium. Since the size of exosomes is limited by that of the parent MVB, exosomes are generally thought to be smaller than most other EVs, from about 30 to 150 nanometres (nm) in diameter: around the same size as many lipoproteins but much smaller than cells. Compared with EVs in general, it is unclear whether exosomes have unique characteristics or functions or can be separated or distinguished effectively from other EVs. EVs including exosomes carry markers of cells of origin and have specialized functions in physiological processes, from coagulation and intercellular signalling to waste management. Consequently, there is a growing interest in clinical applications of EVs as biomarkers and therapies alike, prompting establishment of an International Society for Extracellular Vesicles (ISEV) and a scientific journal devoted to EVs, the Journal of Extracellular Vesicles.
Senile osteoporosis, has been recently recognized as a geriatric syndrome with a particular pathophysiology.
DNA polymerase subunit gamma is an enzyme that in humans is encoded by the POLG gene. Mitochondrial DNA polymerase is heterotrimeric, consisting of a homodimer of accessory subunits plus a catalytic subunit. The protein encoded by this gene is the catalytic subunit of mitochondrial DNA polymerase. Defects in this gene are a cause of progressive external ophthalmoplegia with mitochondrial DNA deletions 1 (PEOA1), sensory ataxic neuropathy dysarthria and ophthalmoparesis (SANDO), Alpers-Huttenlocher syndrome (AHS), and mitochondrial neurogastrointestinal encephalopathy syndrome (MNGIE).
Prohibitin, also known as PHB, is a protein that in humans is encoded by the PHB gene. The Phb gene has also been described in animals, fungi, plants, and unicellular eukaryotes. Prohibitins are divided in two classes, termed Type-I and Type-II prohibitins, based on their similarity to yeast PHB1 and PHB2, respectively. Each organism has at least one copy of each type of prohibitin gene.
P2X purinoceptor 4 is a protein that in humans is encoded by the P2RX4 gene. The product of this gene belongs to the family of purinoceptors for ATP. Multiple alternatively spliced transcript variants have been identified for this gene although their full-length natures have not been determined.
A Disintegrin and metalloproteinase domain-containing protein 8 is an enzyme that in humans is encoded by the ADAM8 gene.
Porosomes are cup-shaped supramolecular structures in the cell membranes of eukaryotic cells where secretory vesicles transiently dock in the process of vesicle fusion and secretion. The transient fusion of secretory vesicle membrane at the porosome base via SNARE proteins, result in the formation of a fusion pore or continuity for the release of intravesicular contents from the cell. After secretion is complete, the fusion pore temporarily formed at the base of the porosome is sealed. The porosomes are few nanometers in size and contain many different types of protein, especially chloride and calcium channels, actin, and SNARE proteins that mediate the docking and fusion of the vesicles with the cell membrane. Once the vesicles have docked with the SNARE proteins, they swell, which increases their internal pressure. They then transiently fuse at the base of the porosome, and these pressurized contents are ejected from the cell. Examination of cells following secretion using electron microscopy, demonstrate increased presence of partially empty vesicles following secretion. This suggested that during the secretory process, only a portion of the vesicular contents are able to exit the cell. This could only be possible if the vesicle were to temporarily establish continuity with the cell plasma membrane, expel a portion of its contents, then detach, reseal, and withdraw into the cytosol (endocytose). In this way, the secretory vesicle could be reused for subsequent rounds of exo-endocytosis, until completely empty of its contents.
Protein KIBRA also known as kidney and brain expressed protein (KIBRA) or WW domain-containing protein 1 (WWC1) is a protein that in humans is encoded by the WWC1 gene.
Prostate cancer antigen 3 is a gene that expresses a non-coding RNA. PCA3 is only expressed in human prostate tissue, and the gene is highly overexpressed in prostate cancer. Because of its restricted expression profile, the PCA3 RNA is useful as a tumor marker.
Biochanin A is an O-methylated isoflavone. It is a natural organic compound in the class of phytochemicals known as flavonoids. Biochanin A can be found in red clover in soy, in alfalfa sprouts, in peanuts, in chickpea and in other legumes.
Palmitoylethanolamide (PEA) is an endogenous fatty acid amide, belonging to the class of nuclear factor agonists. PEA has been demonstrated to bind to a receptor in the cell-nucleus and exerts a great variety of biological functions related to chronic pain and inflammation. The main target is thought to be the peroxisome proliferator-activated receptor alpha (PPAR-α). PEA also has affinity to cannabinoid-like G-coupled receptors GPR55 and GPR119. PEA cannot strictly be considered a classic endocannabinoid because it lacks affinity for the cannabinoid receptors CB1 and CB2. However, the presence of PEA has been known to enhance anandamide activity by an "entourage effect".
Clyomys is a South American rodent genus in the family Echimyidae. It contains two species, found in tropical savannas and grasslands from circa 100 m (300 ft) to 1,100 m (3,600 ft) elevation in central Brazil and eastern Paraguay.
