Papillary urothelial neoplasm of low malignant potential: In urologic pathology, PUNLMP, short for papillary urothelial neoplasm of low malignant potential, is an exophytic (outward growing), (microscopically) nipple-shaped (or papillary) pre-malignant growth of the lining of the upper genitourinary tract (the urothelium), which includes the renal pelvis, ureters, urinary bladder and part of the urethra.Bladder augmentation: Bladder augmentation is a surgical alteration of the urinary bladder. It involves removing strips of tissue from the intestinal tract and adding this to the tissue of the bladder.TSPAN12: Tetraspanin-12 (Tspan-12) also known as tetraspan NET-2 (NET2) or transmembrane 4 superfamily member 12 (TM4SF12) is a tetraspanin protein that in humans is encoded by the TSPAN12 gene. Tetraspanin-12 is found in the membrane of a variety of cells.Autoschizis: "Autoschizis" is a term derived from the Greek αὐτο- auto-, meaning "self", and σχίζειν skhizein, "to split". It was introduced in 1998 to describe a novel form of cancer cell death characterized by a reduction in cell size that occurs due to the loss of cytoplasm through self-excision (the cell splits open) without the loss of cell organelles, morphologic degradation of the cells nucleus and nucleolus without the formation of apoptotic bodies and destruction of the cell membrane.Membrane protein: Membrane proteins are proteins that interact with biological membranes. They are one of the common types of protein along with soluble globular proteins, fibrous proteins, and disordered proteins.
