In summary, the TM3 Leydig cell line expresses both ER and ERβ. These receptors may function as nuclear receptors that can down regulate transcription as well as putative plasma membrane receptors capable of decreasing protein kinase C activity....
把细胞比喻成一种东西,细胞的这些器官要考虑到,这个器官是这个东西里的什么以及为什么～nucleus 细胞核plasma membrane 细胞膜cytoplasm 细胞质mitochondria 线粒体ribosomes 核糖体plastids 质体Golgi apparatus 高尔基体ER 内质网lysosome 溶酶体vacuole 液泡cell wall 细胞壁要有创意并且形象～比如说汽车,房子什么的就不用...
The golgi sends materials through vesicles to other organelles and the plasma membrane, which is the outer covering of the cell. Read Cells Nucleus & Membrane-Bound Organelles | Is the Nucleus an Organelle? Lesson Recommended for You Video: Nucleus Lesson for Kids Video: Plant Cell Nucleus |...
They discovered that hormone-stimulated AC activity resides on the plasma membrane (PM) and that various hormones stimulate cAMP synthesis in different cell types (3, 4, 5, 6, 7, 8, 9). These findings established the foundation for the concept of a two-messenger system, with hormones ...
Recently, scientific interest in electric pulses, always more intense and shorter and able to induce biological effects on both plasma and nuclear membranes, has greatly increased. Hence, microdosimetric models that include internal organelles like the nucleus have assumed increasing importance. In this...
A Truncated HIV-1 Tat Protein Basic Domain Rapidly Translocates through the Plasma Membrane and Accumulates in the Cell Nucleus Tat is an 86-amino acid protein involved in the replication of human immunodeficiency virus type 1 (HIV-1). Several studies have shown that exogenous Tat p... E Vive...
Intramembrane particles (IMP) are believed to represent protein-containing structures in the membrane. Hypothalamic arcuate nucleus neuronal plasma membranes from male and female rats studied from birth to adulthood were quantitatively assessed for IMP number and size using freeze-fracture techniques. We ...
Rho proteins reside mainly in the cytosol and are targeted to the plasma membrane (PM) upon specific activation by guanine nucleotide exchange factors (GEFs). Accordingly, most GEFs are also cytosolic or associated with the PM. However, Net1, a RhoA-specific GEF predominantly localizes to the ...
The cell nucleus is a membrane-bound organelle that contains most of the cell's genetic material (DNA) in the form of chromosomes. The main components of the nucleus include the nuclear envelope, a double membrane that encloses the entire organelle a
Regional and temporal specialization in the nucleus: a transcriptionally-active nuclear domain rich in PTF, Oct1 and PIKA antigens a... A truncated HIV-1 Tat protein basic domain rapidly translocates through the plasma membrane and accumulates in the cell nucleus....
