Abstract

Primary immunodeficiencies (ID) lead to a high incidence of cancer, particularly of lymphomas. The risk excess varies according to the type of ID. Cellular IDs carry a very high risk, tumoral IDs have an intermediate risk while deficiencies of non-specific immunity bear no risk. Acquired IDs are also associated with an increased risk of lymphomas. The physiopathogeny of ID-associated lymphomas remains unknown, although several hypotheses have been proposed, including a defective immunological surveillance, repeated viral and antigenic stimulations and DNA repair anomalies.

Translational control by RPL22L1-specific ribosomes enhances DNA repair and chemoresistance.

Ribosome heterogeneity has emerged as a regulatory layer in gene expression, yet its biological roles in cancers remain poorly characterized. Here, we identify RPL22L1, a paralog of the ribosomal protein RPL22, as a key modulator of DNA damage response (DDR) in colorectal cancer cells. DNA damage induces RPL22L1 upregulation and ribosomal incorporation, forming RPL22L1-specific ribosomes. Ribosome profiling reveals that RPL22L1-containing ribosomes preferentially translate mRNAs with highly structured 5' untranslated region (5'UTR). In particular, RPL22L1 enhances the translation of ATRX through a cap-independent mechanism. ATRX subsequently recruits DNA-PKcs to DNA damage sites, thereby enhancing the DNA repair capacity. RPL22L1 loss creates exploitable DDR vulnerabilities, sensitizing cancer cells to cisplatin and PARP inhibitors in vitro and in vivo. Collectively, these findings uncover a specialized ribosome-mediated translational program in DDR and highlight RPL22L1 as a potential therapeutic target in DDR-based cancer therapy.

Hypoxia-induced genetic instability--a calculated mechanism underlying tumor progression.

The cause of human cancers is imputed to the genetic alterations at nucleotide and chromosomal levels of ill-fated cells. It has long been recognized that genetic instability-the hallmark of human cancers-is responsible for the cellular changes that confer progressive transformation on cancerous cells. How cancer cells acquire genetic instability, however, is unclear. We propose that tumor development is a result of expansion and progression-two complementary aspects that collaborate with the tumor microenvironment-hypoxia in particular, on genetic alterations through the induction of genetic instability. In this article, we review the recent literature regarding how hypoxia functionally impairs various DNA repair pathways resulting in genetic instability and discuss the biomedical implications in cancer biology and treatment.

Iron-sulfur cluster proteins: electron transfer and beyond.

Iron-sulfur clusters-containing proteins participate in many cellular processes, including crucial biological events like DNA synthesis and processing of dioxygen. In most iron-sulfur proteins, the clusters function as electron-transfer groups in mediating one-electron redox processes and as such they are integral components of respiratory and photosynthetic electron transfer chains and numerous redox enzymes involved in carbon, oxygen, hydrogen, sulfur and nitrogen metabolism. Recently, novel regulatory and enzymatic functions of these proteins have emerged. Iron-sulfur cluster proteins participate in the control of gene expression, oxygen/nitrogen sensing, control of labile iron pool and DNA damage recognition and repair. Their role in cellular response to oxidative stress and as a source of free iron ions is also discussed.
