Definitions

• This enzyme's presence can be detected easily by providing cells with a substrate that yields a blue-colored product upon enzymatic cleavage.
• these investigators observed an age-dependent rise in this senescence-associated ⁇ -galactosidase in human skin, suggesting that the accumulation of the enzyme provides a marker for senescence in fibroblasts and keratinocytes in the skin and perhaps other epithelial tissues.
• senescence may have evolved as a mechanism for tumor suppression, and that aging is an indirect effect of this circumstance. Because constraints on growth control are absent from tumor cells, such cells most likely have switched off the expression of genes whose products promote or maintain the senescent state. For example, in vitro studies have indicated that senescence can be partially circumvented by the inactivation of tumor suppressor proteins such as the retinoblastoma tumor suppressor gene RBI (Weinberg, Cell 81:323-330, 1995). This suggests the possibility that the loss of functional tumor suppressor genes in vivo could permit cells to gain a replicative advantage and eventually to undergo immortalization.

• a novel gene has been identified that is expressed at high levels in senescent cells.
• a cDNA corresponding to the novel gene has been isolated and sequenced and found to contain an open reading frame encoding a protein having a deduced molecular weight of 23 kilodaltons (kDa) (SEQ ID NO: l).
• kDa kilodaltons
• this gene has been named "p23.”
• Messenger RNA transcribed from p23 is reproducibly detectable at higher levels in senescent than in proliferating cultured normal human mammary epithelial cells.
• p23 The function of p23 is not known, but analysis of its deduced amino acid sequence (SEQ ID NO:2) suggests that it belongs to a family of transmembrane proteins known as the "PMP 22" family or "epithelial membrane protein” (EMP) family (e.g., see Taylor et al., J. Biol. Chem. 270:28824-28833, 1995; Lobsiger et al., Genomics 36:379-387, 1996; Taylor and Suter, Gene 175:115-120. 1996).
• PMP 22 family
• EMP epidermal membrane protein
• Immunospecific reagents capable of specifically binding p23 may be produced by hybridoma or by repeated injection of the purified protein or selected peptides derived from p23 in combination with an appropriate adjuvant (e.g., Freund's, ISCOMs, or the like) into a suitable animal such as a rabbit, sheep, or goat.
• an appropriate adjuvant e.g., Freund's, ISCOMs, or the like
• Therapeutic applications include binding partners that inhibit the binding of p23 to ligands that normally bind to it. thus promoting cell proliferation in the treated cell.
