Ubiquitin protein has a conserved amino acid sequence, found in all eukaryotes and it is important in many of cellular functions .The increase or decrease in the ubiquitin level lead to causing many diseases including cancer .The aim of this study is to measure the concentration of ubiquitin c protein in blood serum of lung cancer patients and healthy control subjects by using ELISA technique. The Mean ± SD for ubiquitin c protein was (7.51 ± 5.76) in blood serum of the normal healthy subject and Std. Error mean was (1.82). While the Mean ± SD was (10.99 ± 4.56 ) for ubiquitin c protein in serum of lung cancer patients and Std. Error mean was (1.44) .The results showed no statistically significance the P value ( 0.15) between the protein concentration in the serum of patients with lung cancer compared to the serum concentration of healthy normal subjects.
