“…Of the more than 30 members of this family, only ADAM-10, -15, and -17 have been characterized in vascular cells [10]. ADAM-10 has also been identified in distinct areas of the human brain [11,12] and peripheral structures [13,14] (Table 1). ADAMs with a thrombospondin domain (ADAMTS) form another group of metalloproteinases.…”

Degradation of the extracellular matrix is an important feature of embryonic development, morphogenesis, angiogenesis, tissue repair and remodeling. It is precisely regulated under physiological conditions, but when dysregulated it becomes a cause of many diseases, including atherosclerosis, osteoarthritis, diabetic vascular complications, and neurodegeneration. Various types of proteinases are implicated in extracellular matrix degradation, but the major enzymes are considered to be metalloproteinases such as matrix metalloproteinases (MMPs) and disintegrin and metalloproteinase domain (ADAMs) that include ADAMs with a thrombospondin domain (ADAMTS).This review discusses involvement of the major metalloproteinases in some age-related chronic diseases, and examines what is currently known about the beneficial effects of their inhibitors, used as new therapeutic strategies for treating or preventing the development and progression of these diseases.

“…Notch-ligand interactions result in the proteolytic cleavage and release of the Notch intracellular domain (NICD), 2 which translocates to the nucleus to form a complex with recombination signal-binding protein for immunoglobulin J region (Rbpj) and Mastermind-like to regulate transcription (9 -12). This canonical signaling pathway leads to the transcription of Hairy Enhancer of Split (Hes)1, -5, and -7 and Hes related with YRPW motif (Hey)1, -2, and -L. Skeletal cells express Notch1, Notch2, and low levels of Notch3 transcripts (13)(14)(15).

Notch receptors are determinants of cell fate and function and play a central role in skeletal development and bone remodeling. Hajdu Cheney syndrome, a disease characterized by osteoporosis and fractures, is associated with NOTCH2 mutations resulting in a truncated stable protein and gain-of-function. We created a mouse model reproducing the Hajdu Cheney syndrome by introducing a 6955C3 T mutation in the Notch2 locus leading to a Q2319X change at the amino acid level. Notch2Q2319X heterozygous mutants were smaller and had shorter femurs than controls; and at 1 month of age they exhibited cancellous and cortical bone osteopenia. As the mice matured, cancellous bone volume was restored partially in male but not female mice, whereas cortical osteopenia persisted in both sexes. Cancellous bone histomorphometry revealed an increased number of osteoclasts and bone resorption, without a decrease in osteoblast number or bone formation. Osteoblast differentiation and function were not affected in Notch2 Q2319X cells. The pre-osteoclast cell pool, osteoclast differentiation, and bone resorption in response to receptor activator of nuclear factor B ligand in vitro were increased in Notch2 Q2319X mutants. These effects were suppressed by the ␥-secretase inhibitor LY450139. In conclusion, Notch2 Q2319X mice exhibit cancellous and cortical bone osteopenia, enhanced osteoclastogenesis, and increased bone resorption.Notch proteins are four single-pass transmembrane receptors that play a critical role in cell fate decisions ( Fig. 1) (1-4). Notch regulates cell renewal and plays a role in skeletal development and homeostasis and in osteoblast and osteoclast differentiation (4 -8). Jagged1 and -2 and DeltaLike1, -3, and -4 are the five classic Notch ligands (4). Notch-ligand interactions result in the proteolytic cleavage and release of the Notch intracellular domain (NICD), 2 which translocates to the nucleus to form a complex with recombination signal-binding protein for immunoglobulin J region (Rbpj) and Mastermind-like to regulate transcription (9 -12). This canonical signaling pathway leads to the transcription of Hairy Enhancer of Split (Hes)1, -5, and -7 and Hes related with YRPW motif (Hey)1, -2, and -L. Skeletal cells express Notch1, Notch2, and low levels of Notch3 transcripts (13-15). Activation of Notch in undifferentiated and differentiated osteoblasts inhibits cell differentiation and function and causes osteopenia (16,17). In contrast, activation of Notch1 in osteocytes causes a pronounced increase in bone mass due to a suppression of bone resorption (18). Results from the conditional inactivation of Notch1 and Notch2 in the developing skeleton confirmed the inhibitory role of Notch in osteoblastogenesis (6,19). Whereas substantial work has characterized the consequences of Notch1 gain-of-function in the skeleton, there is limited knowledge on the function of Notch2 in the postnatal skeleton. This knowledge is particularly important because Notch1 and Notch2 do not have redundant functions, and Notch1 inhibits, wh...

“…Furthermore, Notch signaling blocks chondrocyte maturation, resulting in shortened skeletal elements that lack ossi®cation [Crowe et al, 1999]. Notch2 and Kuzbanian, a metallodisintegrin implied in the activation of Notch, were reported to be expressed in skeletal tissue and by osteosarcoma cells [Dallas et al, 1999], and initial studies suggest that overexpression of Notch1 antagonizes osteoblast differentiation [Tezuka et al, 1998]. However, there is no information regarding the expression and regulation of other Notch receptors and their ligands in osteoblasts.…”

Glucocorticoids have important effects on osteoblastic replication, differentiation, and function, and the Notch family of receptors is considered to play a role in osteoblastic cell differentiation. We postulated that cortisol could regulate Notch and Notch ligand expression in osteoblastic cells, providing an additional mechanism by which glucocorticoids could regulate osteoblastic differentiation. We examined the expression and regulation of Notch1, 2, 3, and 4 and their ligands Jagged 1 and 2 and Delta 1 and 3 by cortisol in cultures of osteoblastic MC3T3-E1 cells. Cortisol caused a time-dependent increase in Notch1 and 2 mRNA levels in MC3T3 cells. Notch3 and 4 were not detected in the presence or absence of cortisol. MC3T3 cells expressed Delta 1 and Jagged 1 but not Jagged 2 or Delta 3 mRNAs, and cortisol did not have a substantial effect on the expression of any of these ligands. Cortisol increased the rate of Notch1 and 2 transcription and, in transcriptionally arrested cells, did not modify the decay of the transcripts, indicating a transcriptional level of control. In conclusion, cortisol stimulates Notch1 and 2 transcription in osteoblasts. Since Notch signaling appears to play a negative role in osteoblastic differentiation, its increased expression could be relevant to the actions of cortisol in bone.
