In our study, breast tumors overexpressing TFDP1 had high expression of p16, cyclin E and cyclin B1 Table 4as described in hepatocellular carcinoma [ 20 ]. Furthermore, our results suggest the role for CUL4A as part of the development of breast tumors in general, mainly through deregulation of cell cycle checkpoints. Thus, NSUN5 DNA methylation-associated inactivation, through its linked defect in 28S rRNA methylation, represents a bona fide mechanism that explains how human gliomas adapt to challenging cellular stress conditions by depleting overall synthesis while also promoting specific translational programs.

The influence of second and further lines of treatment, in particular the administration of an anti-EGFR agent after the discontinuation of the treatment of the study, was examined. As most of these markers are associated with basal-like phenotype of breast cancer, these associations may be due to the unique presence of the Amp13q34 in basal-like tumors as we previously reported [ 11 ].
The enhanced growth of cancer cells often requires an increase in global protein synthesis that it is strongly linked to increased ribosome activity [ 434548 ]. This RNA chemical modification also acts at the level of tRNAs, where loss of the 5-methylcytosine RNA-methyltransferase NSUN2 drives a global reduction in protein synthesis [ 5634 ] and altered translational programs [ 56 ], in a similar manner to that which occurs upon the loss of DKC1 [ 343753 ].

This idea is also supported by the existence of specialized ribosomes and complex machineries associated with these structures and rRNAs [ 4142 ], in addition to the presence of mutations in ribosomal proteins in cancer-associated syndromes [ 7 ]. Translational control is also impaired in human X-DC patients [ 353 ]. Analyses of larger series of this tumor subtype will allow us to confirm the specificity of this aberration and, importantly, its possible use as a clinical marker of basal-like tumors.
Received : 14 July Altogether, these findings demonstrated that Amp13q34 was significantly associated with a higher expression level of both CUL4A and TFDP1, but given that there are cases without the amplification showing protein overexpression, Amp13q34 was not the exclusive mechanism causing overexpression of these genes. Results were analyzed with BioEdit software and methylated cytosines were mapped using BSMap software.

This finding may emphasize the interest in identifying molecular features that discriminate each of the sporadic and familial breast cancer subtypes, rather than comparing each group of familial breast cancer with sporadic tumors.
Significantly for rRNA, in addition to pseudouridine, another modification, that of 5-methylcytosine, seems to have a central regulatory role [ 31 ].
At Casa del Mar, Barcelona. Discussion In the present study, we have characterized the genomic amplification at the human 13q34 chromosomal region in familial and sporadic breast cancer cases. In addition, we associated Amp13q34 with other immunohistochemical and clinical tumor features previously analyzed on a subset of the sample set out of samples [ 3334 ].

These tumor features do not correspond to the ones found in Amp13q34 tumors, which are mainly ER and PR negative Table 4 ; thus, GAS6 may not be the target gene in the Amp13q34, but may still play a role in other breast cancers. Once we had determined in glioma cell lines and mouse models the effects of NSUN5 epigenetic silencing, we studied the impact of NSUN5 promoter CpG island hypermethylation in human primary gliomas.
Compliance with ethical standards Conflict of interest M. Casa Asia and Caixabank. We examined whether other genetic and epigenetic alterations of clinical relevance in glioma [ 3250 ] helped define patients with NSUN5 methylation-associated extended survival.
