Ribosome has been considered as the fundamental macromolecular machine involved in protein synthesis in both prokaryotic and eukaryotic cells. This protein synthesis machinery consists of several rRNAs and numerous proteins. All of these factors are synthesized, translocated and assembled in a tightly regulated process known as ribosome biogenesis. Any impairment in this process causes development of several diseases like cancer. According to growing evidences, cancer cells display alteration of several ribosomal proteins. Besides, most of them are considered as key molecules involved in ribosome biogenesis, suggesting a correlation between those proteins and formation of ribosomes. Albeit, defective ribosome biogenesis in several cancers has gained prime importance, regulation of this process in cancer stem cells (CSCs) are still unrecognized. In this article, we aim to summarize the alteration of ribosome biogenesis and ribosomal proteins in CSCs. Moreover, we want to highlight the relation of ribosome biogenesis with hypoxia and drug resistance in CSCs based on the existing evidences. Lastly, this review wants to pay attention about the promising anti-cancer drugs which have potential to inhibit ribosome biogenesis in cancer cells as well as CSCs.
