Protoporphyria

"Protoporphyria" Meaning

Erythropoietic protoporphyria (EPP) is a rare genetic disorder that affects the production of heme, a green pigment in hemoglobin found in red blood cells. It is caused by a mutation in the ALAS2 gene. The condition is characterized by an increase in protoporphyrin levels in the blood, particularly in the erythrocytes. The accumulation of protoporphyrin causes photosensitivity, leading to blistering erythema, pain, and swelling of sun-exposed areas, as well as other symptoms.

Protoplasts

A term from biology and cell biology. Protoplasts are a type of cell that consists of the cell contents, including the cytoplasm, nucleus, and other organelles, but without the cell wall. They are often obtained by enzymatic removal of the cell wall from intact cells, particularly plant cells. In other words, protoplasts are cells that have not yet developed a rigid cell wall or have lost it through enzymatic treatment. They are commonly used in plant genetic engineering and biotechnology research to study and manipulate gene expression, cell signaling, and plant development. Protoplasts are also used in various biotechnological applications, such as the production of plant vaccines, the creation of transgenic plants, and the development of new cell-based therapies.

Protoporphyrin

Protoporphyrin is a type of porphyrin, a family of organic compounds with a porphyrin macrocycle. Protoporphyrin IX (PPIX), also known as porphyrin IX, is a key intermediate in the biosynthesis of heme, a crucial component of hemoglobin, myoglobin, and other hemoproteins. A porphyrin is a macrocyclic compound comprising four modified pyrrole subunits interconnected at their α carbon atoms via methine bridges (CH-). The four pyrrole groups are arranged to create an equilateral rectangle, with a central coordinated atom (iron in heme, magnesium in chlorophyll), surrounded by four reduced-side pyrrole groups and four axial ligands. Protoporphyrin IX can be obtained from the interaction of four molecules of δ-aminolaevulinic acid (ALA) via the porphyrin pathway. The enzyme ferrochelatase binds iron to the porphyrin IX ring in a reaction called ferrochelatase or ferrocheletation, producing heme. Porphyrins, including protoporphyrin IX, are fluorescent compounds with a characteristic intense red fluorescence under ultraviolet light. This property has been utilized for biological and photodynamic applications, such as photosensitizing light-sensitive reactions in reactive oxygen species in medical treatments like photodynamic therapy for cancer. Abnormal levels of protoporphyrin IX have been linked with various diseases related to the biosynthesis pathways of heme, such as porphyrias and some forms of anemia.

Protopterus

Protopterus is an ancient genus of lungfish from the order Neoceratodontiformes. It is one of the five living genera of lungfish, which are places on the main branch of the Chordata with other tetrapods (four-legged vertebrates).
