Abstract

This study revealed that the content of protein S29 in ribosomes of cancer cell line A549 was distinctly low (equivalent to about 30% of that of 2BS). The conclusion was acquired based on the ratios of spot volume of ribosomal protein S29 to that of several other ribosomal proteins (S29 / L37a, S29 / L38, S29 / S27 and S29 / S28) in the same gel plate. The possible biological roles of ribosomal protein S29 in malignant transformation and translation regulation are briefly discussed.
