    Streszczenie angielskie: Matrix metalloproteinases (MMP) are a large family of hydrolases contributed to both normal and pathological tissue remodeling. There is an accumulated data showing that bacterial lipopolisaccharide can stimulate MMPs expression in many models in vitro. The aim of this study was to assess the MMP-2 and 9- expression in LS 180 cell line stimulated with LPS in dose of 0.14 ćg/ml. Into our experimental work we employed many different techniques such as: RT-PCR, fluorescent immunocytochemistry and zymography. According to our data there were no differences in MMP-2 and MMP-9 expression as was shown by means of RT-PCR and fluorescent immunocytochemistry. Because immunocytochemistry was not able to distinguish active and inactive forms of metalloproteinases zymography was incorporated to measure amounts of different forms of MMP-2 and MMP-2 secreted to culture medium. Assessment of the obtained results showed slightly elevated level of proMMP-9 and MM-9 after LPS stimulation. For MMP-2 similar effects was not seen.

    Streszczenie angielskie: Epstein-Barr (EBV) is a powerful immortalizing virus for human B lymphocytes in vitro and is assoxciated with several human neoplasms in vivo. Chronic lymphocyte leukaemic (CLL) cells might be infected by the virus but can not proliferative whereas normal resting B lymphocytes produce immortalized cell lines after infection. Since the pRb,p 107 and p130, together with p27, play critical roles in controlling the mammalian cell division cycle, we have investigated the expression of this genes following EBV immortilisation of primary B-lymphocytes comparing to cultured B-CLL cells. In this report, we show that EBV decreases the pRb and p130 mRNA gene expression and drives down the mRNA level of p27 gene expression, which is extremely high in B-CLL lymphocytes. This is achieved by a strategy involving "silencing" of critical cell division cycle genes: pRb, p130. Viral proteins may take part in that process. Increased expression of p27 in B-CLL cells may be responsible for maintenance of anergic state.
