Ubiquitination is a reversible post-translational modification that regulates function of conjugated proteins by decorating with ubiquitin chains-polymer of ubiquitin-in most cases. The discovery of linear ubiquitin chains and the linear ubiquitin chain assembly complex (LUBAC) ubiquitin ligase complex can be considered as paradigm shift in the ubiquitin research because the linear ubiquitin chain is generated via the N-terminal Met of ubiquitin, although the other ubiquitin chains are generated via one of seven Lys residues in ubiquitin. Moreover, ubiquitination is distributed throughout eukaryotic kingdoms; however, no linear ubiquitination could be found in lower eukaryotes including yeasts. Although the involvement of ubiquitination in proteolysis is well-documented, linear ubiquitination plays crucial roles in immune signaling and cell death regulation. Moreover, dysregulation of LUBAC-mediated linear ubiquitination underlies various human diseases including autoinflammation and cancer. Here, I introduce how linear ubiquitination was discovered and outline a brief history of linear ubiquitination research.

Background XPDLys751Gln polymorphism may modulate inter-individual variation in repair capacity of DNA, which may enhance a person's susceptibility to develop colorectal cancer (CRC). The analysis ofXPDLys751Gln polymorphism may provide important information for identifying high-risk individuals and for selecting the most appropriate treatment for poor prognostic CRC patients. Objective The overall objective was to find out the association ofXPDLys751Gln gene polymorphism with the risk of having a colorectal cancer and the ultimate clinical outcomes. In this study a total of 300 subjects (CRC and Controls), were genotyped forXPDLys751Gln. Methods Using PCR-RFLP methods, the association ofXPDLys751Gln gene polymorphism with the risk of having a colorectal cancer was studied. In addition to overall risk assessment, genotyping results were also investigated with respect to the lifestyle risk factors, patients treated with oxaliplatin-based chemotherapy and clinicopathological characteristics. Results The overall correlation between theXPDLys751Gln genetic variation and the CRC risk was observed to be significant with both the homozygous variant genotype Gln/Gln as well as heterozygous genotype Lys/Gln being associated with the increased risk of CRC. Additional stratified analyses revealed thatXPDLys751Gln variants remarkably increased risk of CRC in males and younger individuals (<= 50 years), Naswar users (8.09-fold) and high intake of red meat. Conclusions Our findings suggest that the relationship between theXPDLys751Gln variants and lifestyle factors modulates the risk for CRC in Pakistani population.
