CHAPTER 3<br />

RESULTS<br />

Fig.3.4.5a Gene expression of NF-kB (p65) and iNOS gene in EL-4 cells which had received<br />

medium from irradiated cells. EL-4 cells cultured for 2 h in presence of different conditioned<br />

media. β-Actin gene expression in each group was used as an internal control. Ratio of intensities<br />

of NF-kB (p65) and iNOS band to that of respective β-actin band as quantified from gel pictures<br />

are shown above each gel picture. Key: Lane 1, control EL-4 cells; Lane 2, γ irradiated EL-4<br />

cells; Lane 3, EL-4 cells receiving medium from γ irradiated EL-4 cells; Lane 4, EL-4 cells<br />

receiving medium from L-NAME treated and γ irradiated EL-4 cells; Lane 5, EL-4 cells<br />

receiving medium from cPTIO treated and γ irradiated EL-4 cells; Lane 6, EL-4 cells receiving<br />

medium from LPS-stimulated (500ng/ml), L-NAME treated and γ irradiated RAW 264.7 cells;<br />

Lane 7, EL-4 cells receiving medium from LPS-stimulated (500ng/ml), cPTIO treated and γ<br />

irradiated RAW 264.7 cells. Data represents means ± SE of three independent experiments;<br />

significantly different from unirradiated controls: *P < 0.05, **P < 0.01.<br />
