Given the task definition and input, reply with output. In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: Arginine deiminase (ADI) and L-arginine (L-Arg) can act as anti-tumor agents in-vitro and in-vivo. However, the mechanism of ADI and L-Arg as anti-tumor agents has not been clearly shown.', 'With the goal of understanding the role of ADI and L-Arg in inhibition of cell growth, we used the Ramos human lymphoma cell line, which is known to be ADI-sensitive, and observed the p53 and NF-Bp65 protein expression after ADI and arginine treatment. After determining an optimal experimental ADI concentration (0.01 U/ml), we studied the effects of ADI treatment, when combined with different concentrations of L-arginine (control, ADI only, ADI with 10 mM/ml Arg, ADI with 30 mM/ml Arg, and ADI with 50 mM/ml Arg). An MTT assay was used to assess cell survival after treatment, Western blot analysis to determine the levels of the NF-Bp65, p53 and NO mediators and nitric oxide assays were used to determine nitrite levels.\Question: Does l-arginine enhance arginine deiminase induced human lymphoma cell growth inhibition through NF-kBp65 and p53 expression in vitro?
L-arginine enhanced ADI-induced inhibited cell growth through expression of NF-Bp65 and p53 in a dose-dependent manner.
