Human sex chromosomes, which are morphologically and genetically different, share few regions of homology. Among them, only pseudoautosomal regions (PARs) pair and recombine during meiosis. To better address the complex biology of these regions, we sequenced the telomeric 400 kb of the long arm of the human X chromosome, including 330 kb of the human Xq/YqPAR and the telomere. Sequencing reveals subregions with distinctive regulatory and evolutionary features. The proximal 295 kb contains two genes inactivated on both the inactive X and Y chromosomes [ SYBL1 and a novel homologue ( HSPRY3 ) of Drosophila sprouty ]. The GC-rich distal 35 kb, added in stages and much later in evolution, contains the X/Y expressed gene IL9R and a novel gene, CXYorf1, only 5 kb from the Xq telomere. These properties make Xq/YqPAR a model for studies of region-specific gene inactivation, telomere evolution, and involvement in sex-limited conditions.

The identification of differentially expressed genes in tumour cells should have important implications in understanding carcinogenesis and developing new therapeutic and prognostic biomarkers. We have combined PCR-based cDNA subtraction and Northern blotting to identify truly differentially expressed genes in breast cancer cell line SKBR3 as compared to normal human mammary epithelial cells (HMEC). Hybridizing probe molecules were rescued from the Hybond N+ membranes and then PCR reamplified. The PCR reamplification is possible due to the fact that all probe molecules contain the same pair of adapter sequences on both ends. After cloning and sequencing three known genes, ribosomal protein L19 (RPL19), ADP/ATP carrier protein and ErbB-2 with high-elevated mRNA levels in SKBR3 were identified. In addition, two overexpressed genes with unknown functions, CXYorf1-related protein and hypothetical protein PRO2605, were found. High-titer andibodies against the recombinant RPL19 were detected in 5 patients out of 50 patients investigated. Thus, the present novel strategy based on the combination of PCR-based cDNA subtraction and Northern blotting should facilitate the identification of truly differentially expressed biomarkers, which may offer the potential to determine the proper drug for an individual patient at a given stage of disease or treatment.
