Schwannoma-derived growth factor (SDGF) was initially isolated from schwannoma cells as a mitogen for glial cells and fibroblasts. The present data show that SDGF causes the morphological and molecular differentiation of rat PC12 cells in a manner similar to, but distinguishable from nerve growth factor (NGF). It also promotes PC12 survival in serum-free conditions. SDGF induced changes include neurite outgrowth and the induction of the mRNAs for
GAP-43
and
transin
, proteins which are highly expressed in axons. In addition, both SDGF and NGF induce the transcription factor, NGFI-A. The time course of the response to SDGF is similar to that for NGF. Gap-43 mRNA induction by both SDGF and NGF is inhibited by dexamethasone, but dexamethasone has no effect on NGFI-A mRNA synthesis. These observations show that SDGF has a differentiation and survival promoting effect on PC12 cells in addition to its mitogenic activity on glial cells and fibroblasts.

The role of matrix metalloproteinases (
MMP-3
and MMP-9), tissue inhibitor of MMP (TIMP-2), and
GAP-43
(growth-associated-protein) in neocerebellar vermis lobules during postnatal histogenesis was studied after challenge with cisplatin (cisPt). CisPt is one of the most effective and widely used cytotoxic agents in the treatment of a variety of malignancies, in both children and adult patients. A single injection of cisPt to 10-day-old rats altered the spatiotemporal MMP/TIMP expression balance and provoked a decrease in GAP43 immunoreactivity. The imbalance appeared one day (PD11) after cisPt injection, producing disorder of cerebellum histogenesis processes in which MMPs might be involved, i.e. genesis of granule cells, Purkinje cell differentiation and synaptogenesis. Following the early injury, a simultaneous increase in MMP and TIMP expression in the ML was noticed at PD17, likely initiating recovery of Purkinje cell dendrite growth and remodelling processes. However, disturbances at the beginning of recovery phase had emerged, probably due to the down-regulation of
GAP-43
after cisPt treatment. The data provide further support for the usefulness of cisPt as a tool for the study of morphological and functional changes in the CNS during postnatal development.
