This invention relates generally to methods for the diagnosis and therapeutic treatment of Friedreich Ataxia. Friedreich ataxia (FRDA) is an autosomal recessive, degenerative disease that involves the central and peripheral nervous system and the heart. A gene, X25, was identified in the critical region for the FRDA locus on chromosome 9q13. The gene encodes a 210 amino acid protein, frataxin, that has homologues in distant species such as C. elegans and yeast. A few FRDA patients have been found to have point mutations in X25, but the vast majority are homozygous for a variable, unstable GAA trinucleotide expansion in the first X25 intron. Mature X25 mRNA was severely reduced in abundance in individuals with FRDA. Carriers and individuals at risk for developing FRDA can be ascertained by the methods of the present invention. Further, the methods of the present invention provide treatment to those individuals having FRDA.

Described is a novel family of cell surface serpentine transmembrane antigens. Two of the proteins in this family are exclusively or predominantly expressed in the prostate, as well as in prostate cancer, and thus members of this family have been termed “STEAP” (serpentine transmembrane antigens of the prostate). Four particular human STEAPs are described and characterized herein. The human STEAPs exhibit a high degree of structural conservation among them but show no significant structural homology to any known human proteins. The prototype member of the STEAP family, STEAP-1, appears to be a type IIIa membrane protein expressed predominantly in prostate cells in normal human tissues. Structurally, STEAP-1 is a 339 amino acid protein characterized by a molecular topology of six transmembrane domains and intracellular N- and C-termini, suggesting that it folds in a “serpentine” manner into three extracellular and two intracellular loops. STEAP-1 protein expression is maintained at high levels across various stages of prostate cancer. Moreover, STEAP-1 is highly over-expressed in certain other human cancers.

The invention discloses a method for screening a biomarker related to severe oligoasthenospermia. The method comprises carrying out deep mass spectrometry on multiple sperm protein uncoded amino acids of severe oligoasthenospermia through a NanoHPLC-MS / MS mass spectrometry system and an unlabeled quantitative proteomics method, searching the mass spectrometry data through a nonfinite amino acid protein modification analysis method, carrying out multivariable gaussian mixture distribution clustering analysis to identify the non-coding amino acids in the sperm protein group as much as possible, and comparing the non-coding amino acids of the normal and patient sperm protein groups to obtain protein uncoded amino acid sites related to severe oligoasthenospermia, wherein the protein uncoded amino acid sites are used as molecular markers of severe oligoasthenospermia. The method provides novel diagnostic and therapeutic targets for severe oligoasthenospermia.

This invention provides a novel pyrin-only protein (POP2), polypeptides, nucleic acids encoding them and methods for making and using them. The polypeptides of this invention have nuclear factor-κB (NF-κB) modulating activity. NF-κB is pivotal for transactivation of cell-cycle regulatory, cytokine and adhesion molecule genes and is dysregulated in many cancers, neurodegenerative disorders, and inflammatory diseases. Proteins with Pyrin and / or caspase recruitment (CARD) domains have roles in apoptosis, innate immunity, and inflammation. Many pyrin domain proteins modulate NF-KB activity as well as participate in assembling both the perinuclear “apoptotic speck” and the pro-IL1β / IL-18 converting inflammasome complex. ‘Pyrin-only’ proteins are attractive as negative regulators of pyrin domain-mediated functions and one such protein, POP1, has been reported. We teach a second Pyrin-only protein (POP2). POP2 is a 294 nt single exon gene located on human chromosome 3 encoding a 97 amino acid protein with sequence and predicted structural similarity to other pyrin domains. Highly similar to pyrin domains in CATERPILLER (CLR, NLR, NALP) family proteins, POP2 is less like the prototypic Pyrin and ASC pyrin domains. POP2 is expressed principally in peripheral blood leukocytes and displays both cytoplasmic and nuclear expression patterns in transfected cells. TNFα-stimulated and p65 (RelA) induced NF-KB-dependent gene transcription is inhibited by POP2 in vitro by a mechanism involving changes in NF-κB nuclear import or distribution. While colocalizing with ASC in perinuclear specks, POP2 also inhibits the formation of specks by the CLR protein CIAS1 / NALP3. Together these observations indicate that POP2 is a negative regulator of NF-KB activity that may influence the assembly of pyrin-domain dependent complexes.

There are provided trehalose transporter gene and a method of introducing trehalose into cells by using the gene. Candidates for the trehalose transporter genes were searched in P. vanderplanki EST, resulting in being obtained cDNA designated as Tret1. Tret1 encodes a 504 amino acid protein with 12 trans-membrane structures. Tret1 expression was induced by desiccation stress and predominant in the fat body. Functional expression of TRET1 in Xenopus oocytes showed that transport activity was specific for trehalose and independent of extracellular pH and electrochemical membrane potential. The direction of transport of TRET1 was reversible depending on the concentration gradient of trehalose. Apparent Km and Vmax of TRET1 for trehalose were extraordinarily high values. These results indicate that TRET1 is a facilitated, high-capacity trehalose-specific transporter. Tret1 is widespread in insects. Furthermore, TRET1 conferred trehalose permeability upon cells including those of vertebrates as well as insects.
