Using an inducible FGFR1 (iFGFR1) prostate mouse model, Acevedo et al have found that iFGFR1 activation by chemical inducers of dimerization (CID) results in prostate adenocarcinoma that is closely associated with EMT, while CID withdrawal causes a full reversion of PIN. Growth-factor receptor tyrosine kinase (RTK) activated pathways Progression of prostate cancer to CRPC is also associated with enhanced expression of growth factors and receptors capable of activating the receptor tyrosine kinase (RTK) pathways

The best way to appreciate the basic tissue organization of the body is through examples in which this organization is displayed in relatively simple form. Exceptions include germ cells, which don't fit the scheme at all, and several specialized varieties of connective tissue which masquerade as epithelium, such as synovial membranes of joint capsules and stria vascularis of the inner ear

Since discovery of the first kinesin, the family has been shown to consist of many members, some of which are important for spindle function during mitosis. The functions of microtubules in vesicle transport and chromosome segregation are dependent on molecular motors that bind to and move along microtubule tracks
A key characteristic of multicellular organisms is specialization By contrast, a multicellular organism is made up of many cells that are dependent on each other to perform these essential functions as a group. In this picture you can see the basement membrane here, with several layers of cells on top, and then in the very top layer you can see some cells which secrete mucous here, here, and here, and other cells that have visible cilia located here, here, and here

30 PamloAug 11, 2011 @ 11:11 amThis a good one but I am afraid i did not get what i wanted 31 AudrinnaAug 25, 2011 @ 6:18 pmI think there should be more about the unknown parts of the cell. The matrix, or inner space created by the cristae, contains the enzymes necessary for the many chemical reactions that eventually transform food molecules into energy
When the bladder is empty, the outermost cells are polygonal or dome-shaped, but when the bladder is full (distended), the thickness of the epithelial layer is less and the outermost cells appear more squamous. 7) Transitional Transitional epithelia is a special type of epithelia restricted to the excretory passages of the urinary system (renal pelvis, most of the urethra and urinary bladder)
Tissue: The Living Fabric
Covering and Lining Membranes Cutaneous membrane, or skin, is an organ system consisting of a keratinized squamous epithelium firmly attached to a thick layer of dense irregular connective tissue . Stratified squamous epithelium is composed of several layers with the cells on the free surface being squamous-shaped and the underlying cells being cuboidal or columnar in shape
SEER Training:Body Tissues
The intercellular matrix may contain special substances such as salts and fibers that are unique to a specific tissue and gives that tissue distinctive characteristics

Yet another is seen in protein digestion, where the presence of partially digested protein in the stomach triggers the secretion of hydrochloric acid and pepsin, the enzyme that digests protein. Positive Feedback and Rapid Change The counterpart to negative feedback is the positive feedback loop, a process in which the body senses a change and activates mechanisms that accelerate or increase that change

Organization of the Body and Body Tissues
2) Fibers which give connective tissue their support are composed of three types: a) Collagen Fibers are the strongest and most abundant and are made of the protein collagen. It consist of an outer keratinized stratified squamous epithlium called the epidermis and an inner layer of dense irregular connective tissue to which it is firmly attached called the dermis
All About the Role of Connective Tissue in the Human Body
Fat tissue can be found in a thin layer beneath the skin, surrounding internal organs and interwoven with other structures, such as bone marrow and breast tissue. In other words: tissue is a grouping of cells, organs are groups of tissue, organ systems are groups of interconnected organs, and a complete organism is a group of organ systems
Animal Tissues: Epithelial Tissue
Likewise, a tissue can sometimes be held together by a sticky substance that coats its cells.There are four main categories of tissues: epithelial, connective, muscle and nervous. Epithelial cells form the thin layer of cells known as the endothelium, which is continuous with the inner tissue lining of organs such as the brain, lungs, skin, and heart
