1.. IntroductionSPARC (secreted protein acidic and rich in cysteine, also known as osteonectin and BM-40) is a 32-kDa calcium-binding glycoprotein secreted by many types of cells, e.g., endothelial cells, fibroblasts, and platelets (Brekken and Sage, 2000).It belongs to a class of proteins termed "matricellular" that are involved in cell-extracellular matrix (ECM) interactions during . All members of this protein family share the three similar domains . During plant growth, development and stress adaption, receptor-like protein kinases (RLKs) are essential components in perceiving and integrating extracellular stimuli and transmitting the signals to activate the downstream signaling pathways. The chemotherapeutic agent nanoparticle albumin-encapsulated (NAB)-paclitaxel has been postulated to exploit SPARC expression to target neoplastic cells. Note: SPARC encodes a cysteine-rich acidic matrix-associated protein that belongs to a family of SPARC-related proteins composed of others six members, that include SPOCK1, SPOCK2, SPOCK3, SPARCL1, SMOC1, SMOC2 (testican-1, -2, -3, SPARC-like 1 (or hevin, Mast9), and SPARC-related modular calcium binding (SMOC)-1, and -2).

The local tissue microenvironment "niche" is composed of cellular and non-cellular components and plays an important role in regulating cell behaviour, during embryogenesis, and in physiologic and pathologic contexts including cancer. We previously showed that androgen-induced expression profiles in prostate development are reactivated in aggressive prostate cancers. Other meats such as lamb and game meats are also good sources. It is secreted by osteoblasts during bone formation, initiating mineralization and promoting mineral crystal formation. The functional significance of SPARC is emphasized by its origin in the first multicellular organisms and its high degree of evolutionary conservation.
