Mitochondrial outer membrane permeabilization (MOMP), is a reason of the higher matrix Ca 2+ levels, which is acts as a trigger for apoptosis. MOMP is the process before apoptosis, which is accompanied to permeability of the inner membrane of the mitochondria (IMM).
Initiation of MOMP involves Bcl-2 family proteins, including BAX and BAK. [1] The outer mitochondrial membrane, typically permeable to molecules smaller than 5 kDa, forms pores during MOMP that allow it to accommodate proteins larger than 100 kDa. During MOMP, it takes about five minutes for all mitochondrial membranes within a cell to ...
Progesterone causes many changes to the genitourinary system. A pregnant woman may experience an increase in the size of the kidneys and ureter due to the increase blood volume and vasculature. Later in pregnancy, the woman might develop physiological hydronephrosis and hydroureter, which are normal. [33]
The mitochondrial permeability transition pore (mPTP or MPTP; also referred to as PTP, mTP or MTP) is a protein that is formed in the inner membrane of the mitochondria under certain pathological conditions such as traumatic brain injury and stroke.
Human ovary with developed corpus luteum. Maternal recognition of pregnancy is a crucial aspect of carrying a pregnancy to full term. Without maternal recognition to maintain pregnancy, the initial messengers which stop luteolysis and promote foetal implantation, growth and uterine development finish with nothing to replace them and the pregnancy is lost.
Image showing trophoblast differentiated into the two layers of cytotrophoblast and syncytiotrophoblast during implantation. It is the outer layer of the trophoblasts and actively invades the uterine wall, during implantation, rupturing maternal capillaries and thus establishing an interface between maternal blood and embryonic extracellular fluid, facilitating passive exchange of material ...
Pregnancy symptoms may be categorized based on trimester as well as region of the body affected. Each pregnancy can be quite different and many people do not experience the same or all of the symptoms. If a person is concerned about their symptoms they should be encouraged to speak with an appropriate healthcare professional. [1]
It modifies the metabolic state of the mother during pregnancy to facilitate energy supply to the fetus. hPL has anti-insulin properties. hPL is a hormone secreted by the syncytiotrophoblast during pregnancy. Like human growth hormone, hPL is encoded by genes on chromosome 17q22-24. It was identified in 1963. [2]
