Abstract:
Chromosome analysis was performed on tumor cells from 15 patients with lung cancer. The G-banding techniques were used for analysis of karyotypes. The results showed that numerical and structural abnormalities were found in each case. Chromosomal numbers varied in a range of 36-240. Aneuploids were present in 91.62% of all cells. The most common numerical alterations were subtriploidies and triploidies. Chromosomes 1, 11, 4, 5, and 3 were most frequently involved in 21 marker chromosomes. It was found that marker chromosomes M1, M3, M4 and M5 were related to chromosome 1 with the breakpoints assigned to 1p11, 1q11, 1p35 and an area of centromere. This result may suggest that breakpoint of chromosome 1 be related to the expression of oncogene of the lung cancer.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
