[Study on expression of cell cycle-related genes in subclonal cell lines of human cervical carcinoma]
1Center of Experimental Medicin, First Hospital of Xi'an Jiaotong University, Xi'an 710061, China.
Objective:
To explore the role of expression of cell cycle-related genes in cervical carcinoma cell lines.
Methods:
A series of expression microarray analysis of two homologous cervical carcinoma subclonal cell lines were initiated by cDNA microarray which represent a set of 234 human cell cycle-related genes.
Results:
In normal medium, the percent of G(1) phase in CS03 cells was higher than in CS07 cells dramatically, but the percent of S phase in CS07 cells was more than in CS03 cells. After cultured 48 h in serum-free medium, the percent of apoptosis cells (sub-G(1) phase) in CS03 cells was higher than in CS07 cells significantly and increased with time. By applying this cDNA microarray, we identified 3 differentially expressed genes in two homologous cell lines, which were BN51, hsp90 and Mcl-1 genes, further identified 3 upregulated genes in CS07 cell line, the ratio of Cy5/Cy3 was 0.480, 0.479 and 0.490 respectively.
Conclusion:
Differential expression of BN51, hsp90 and Mcl-1 genes is associated to various growth patterns of human cervical carcinoma cells.

Cancer-Critical Genes II: Tumor Suppressor Genes
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.
