Malignant fibrous histiocytoma (MFH) is regarded as an undifferentiated pleomorphic sarcoma with unproven histogenesis. We investigated pathobiological characteristics of a rat MFH cell line (MT-9). Immunocytochemically, MT-9 cells and MT-9-induced tumours reacted to vimentin, A3 (rat MFH cell-specific antibody), macrophage markers and alpha-SMA (myofibroblastic marker), indicating that MT-9 showed both histiocytic and (myo)fibroblastic features. Adipogenic supplement-added MT-9 showed increased accumulation of lipid droplets. Addition of BMP-2 or osteogenic supplement to MT-9 enhanced osteoblastic markers (ALP activity, osteocalcin mRNA expression and calcification). TGF-beta1-treated MT-9 revealed increased numbers of alpha-SMA-immunopositive cells, and enhanced protein levels of alpha-SMA and fibronectin, indicating myofibrogenesis. In rat tissues, A3 labelled with immature mesenchymal and perivascular cells in foetuses and neonates, and with marrow stem cells in adults. c-kit mRNA expression was seen in bone marrows and MT-9. Collectively, progenitors of MFH should be sought in lineage of marrow stem cells capable of differentiating into mesenchymal cells.

The present study aimed to evaluate the protective role of resveratrol and curcumin on oxidative testicular damage induced by di-(2-ethylhexyl) phthalate (DEHP). Male Wistar rats were divided into six groups; three groups received oral daily doses of DEHP (2g/kgBW) for 45days to induce testicular injury. Two of these groups received either resveratrol (80mg/kgBW) or curcumin (200mg/kgBW) orally for 30days before and 45days after DEHP administration. A vehicle-treated control group was also included. Another two groups of rats received either resveratrol or curcumin alone. Oxidative damage was observed by decreased levels of total antioxidant capacity (TAC) and glutathione (GSH) and increased malondialdehyde (MDA) level in the testes of DEHP-administered rats. Serum testosterone level as well as testicular marker enzymes activities; acid and alkaline phosphatases (ACP and ALP) and lactate dehydrogenase (LDH) showed severe declines. DEHP administration caused significant increases in the testicular gene expression levels of Nrf2, HO-1, HSP60, HSP70 and HSP90 as well as a significant decrease in c-Kit protein when compared with the control group. Histopathological observations provided evidence for the biochemical and molecular analysis. These DEHP-induced pathological alterations were attenuated by pretreatment with resveratrol and curcumin. We conclude that DEHP-induced injuries in biochemical, molecular and histological structure of testis were recovered by pretreatment with resveratrol and curcumin. The chemoprotective effects of these compounds may be due to their intrinsic antioxidant properties along with boosting Nrf2, HSP 60, HSP 70 and HSP 90 gene expression levels and as such may be useful potential tools in combating DEHP-induced testicular dysfunction.
