Objective:
To assess the correlation of cytogenetic changes with serum vascular endothelial growth factor (VEGF) and serum tartrate resistant acid phosphatase (TRacp-5b) levels among elderly patients with multiple myeloma (MM).
Methods:
Chromosomal changes were analyzed with a modified culturing method in the presence of IL-6. Serum levels of VEGF and TRacp-5b were determined with enzyme-linked immunosorbent assays (ELISA).
Results:
Among the 60 MM patients, chromosomal abnormalities were found in 27 cases, including 22 with numerical abnormalities and 15 with structural abnormalities. Many patients had both numerical and structural abnormalities. For 33 patients with a normal karyotype, the levels of VEGF and TRacp-5b were 117.35 ± 55.26 pg/mL and 4.15 ± 2.15 U/L, respectively, while for 27 patients with an abnormal karyotype, the levels of VEGF and TRacp-5b were 190.26 ± 85.74 pg/ml and 5.96 ± 2.24 U/L, respectively. The difference between the two groups was significant (P<0.05).
Conclusion:
Compared with MM patients with a normal karyotype, the levels of VEGF and TRacp-5b are higher in those with cytogenetic abnormalities.

02:07Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

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.
