Western blot testing of HYAL2 antibody and Lane 1: HeLa; 2: SMMC-7721; 3: COLO320; 4: MCF-7; 5: HT1080 cell lysate Description Hyaluronoglucosaminidase 2, also known as hyaluronidase 2, and LuCa-2, is an enzyme that in humans is encoded by the HYAL2 gene. HYAL2 cDNAs encode a preprotein with an N-terminal signal peptide. Northern blot analysis indicated that the gene was expressed in all human tissues tested except adult brain, and Western blot analysis detected the protein in all mouse tissues examined except adult brain. HYAL2 is a glycosylphosphatidylinositol (GPI)-anchored protein on the cell surface and serves as a receptor for entry into the cell of the jaagsiekte sheep retrovirus (JSRV). The findings of Rai et al.(2001) that HYAL2 is a GPI-anchored protein on the cell surface showed that GFP would likely be cleaved from HYAL2 during GPI addition, leaving HYAL2 on the cell surface and resulting in GFP transit to the lysosome for degradation. Application Notes The stated application concentrations are suggested starting amounts. Titration of the HYAL2 antibody may be required due to differences in protocols and secondary/substrate sensitivity. Immunogen Amino acids 142-157 (VRNWQDKDVYRRLSRQ-human) were used as the immunogen for this HYAL2 antibody. Storage After reconstitution, the HYAL2 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing. Ordering: Phone:858.663.9055 | Fax:1.267.821.0800 | Email:[email protected] Copyright © NSJ Bioreagents.

  • Identification of Novel Genetic Variants Associated with Short Stature in A

Pisani1 · Jan M. Wit4 · Mauro Bozzola5 Received: 1 April 2020 / Accepted: 30 May 2020 © The Author(s) 2020 Abstract Human growth is a complex trait determined by genetic factors in combination with external stimuli, including environment, nutrition and hormonal status. In the past, several genome-wide association studies (GWAS) have collectively identifed hundreds of genetic variants having a putative efect on determining adult height in diferent worldwide populations. Theo- retically, a valuable approach to better understand the mechanisms of complex traits as adult height is to study a population exhibiting extreme stature phenotypes, such as African Baka Pygmies. After phenotypic characterization, we sequenced the whole exomes of a cohort of Baka Pygmies and their non-Pygmies Bantu neighbors to highlight genetic variants associated with the reduced stature. Whole exome data analysis revealed 29 single nucleotide polymorphisms (SNPs) signifcantly associated with the reduced height in the Baka group. Among these variants, we focused on SNP rs7629425, located in the 5′-UTR of the Hyaluronidase-2 (HYAL2) gene. The frequency of the alternative allele was signifcantly increased compared to African and non-African populations. In vitro luciferase assay showed signifcant diferences in transcription modulation by rs7629425 C/T alleles. In conclusion, our results suggested that the HYAL2 gene variants may play a role in the etiology of short stature in Baka Pygmies population.

Todd,2 Qi Qiu,3 Ta o F a n , 3 Richard Y. Zhao,3 William H. Rodgers,3 Hong-Bin Fang,4 Ruth L. Katz,5 Sanford A. Stass,3 and Feng Jiang3 Abstract Purpose: Analysis of molecular genetic markers in biological fluids has been proposed as a powerful tool for cancer diagnosis. We have characterized in detail the genetic signatures in primary non ^ small cell lung cancer, which provided potential diagnostic biomarkers for lung cancer. The aim of this study was to determine whether the genetic changes can be used as markers in sputum specimen for the early detection of lung cancer. Experimental Design: Genetic aberrations in the genes HYAL2, FHIT,andSFTPC were evalu- ated in paired tumors and sputum samples from 38 patients with stage I non ^ small cell lung cancer and in sputum samples from 36 cancer-free smokers and 28 healthy nonsmokers by using fluorescence in situ hybridization. Results: HYAL2 and FHIT weredeletedin84%and79%tumorsandin45%and40%paired sputum, respectively. SFTPC was deleted exclusively in tumor tissues (71%).There was concor- dance of HYAL2 or FHIT deletions in matched sputum and tumor tissues from lung cancer patients (r =0.82,P =0.04;r =0.84,P = 0.03), suggesting that the genetic changes in sputum might indicate the presence of the same genetic aberrations in lung tumors. Furthermore, abnor- mal cells were found in 76% sputum by detecting combined HYAL2 and FHIT deletions whereas in 47% sputum by cytology, of the cancer cases, implying that detecting the combination of HYAL2 and FHIT deletions had higher sensitivity than that of sputum cytology for lung cancer diagnosis.

Johnson Platelet aggregation at the site of atherosclerotic vascular injury is the underlying patho- physiology of myocardial infarction and stroke. To build upon prior GWAS, here we report on 16 loci identified through a whole genome sequencing (WGS) approach in 3,855 NHLBI Trans-Omics for Precision Medicine (TOPMed) participants deeply phenotyped for platelet aggregation. We identify the RGS18 locus, which encodes a myeloerythroid lineage-specific regulator of G-protein signaling that co-localizes with expression quantitative trait loci (eQTL) signatures for RGS18 expression in platelets. Gene-based approaches implicate the SVEP1 gene, a known contributor of coronary artery disease risk. Sentinel variants at RGS18 and PEAR1 are associated with thrombosis risk and increased gastrointestinal bleeding risk, respectively. Our WGS findings add to previously identified GWAS loci, provide insights regarding the mechanism(s) by which genetics may influence cardiovascular disease risk, and underscore the importance of rare variant and regulatory approaches to identifying loci contributing to complex phenotypes.

It is becoming increasingly clear that each of these two regions contains several TSGs. Until now TSGs which were isolated from AP20 and LUCA regions (e.g.G21/NPRL2, RASSF1A, RASSF1C, SEMA3B, SEMA3F, RBSP3) were shown to inhibit tumour cell growth both in vitro and in vivo. Methodology/Principal Findings: The effect of expression HYAL1 and HYAL2 was studied by colony formation inhibition, growth curve and cell proliferation tests in vitro and tumour growth assay in vivo. Very modest growth inhibition was detected in vitro in U2020 lung and KRC/Y renal carcinoma cell lines. In the in vivo experiment stably transfected KRC/Y cells expressing HYAL1 or HYAL2 were inoculated into SCID mice (10 and 12 mice respectively).

  • REPORT Familial Chilblain Lupus, a Monogenic Form of Cutaneous Lupus Erythematosus, Maps to Chromosome 3P
    REPORT Familial Chilblain Lupus, a Monogenic Form of Cutaneous Lupus Erythematosus, Maps to Chromosome 3p Min Ae Lee-Kirsch, Maolian Gong, Herbert Schulz, Franz Ru¨schendorf, Annette Stein, Christiane Pfeiffer, Annalisa Ballarini, Manfred Gahr, Norbert Hubner, and Maja Linne´ Systemic lupus erythematosus is a prototypic autoimmune disease. Apart from rare monogenic deficiencies of complement factors, where lupuslike disease may occur in association with other autoimmune diseases or high susceptibility to bacterial infections, its etiology is multifactorial in nature. Cutaneous findings are a hallmark of the disease and manifest either alone or in association with internal-organ disease. We describe a novel genodermatosis characterized by painful bluish- red inflammatory papular or nodular lesions in acral locations such as fingers, toes, nose, cheeks, and ears. The lesions sometimes appear plaquelike and tend to ulcerate. Manifestation usually begins in early childhood and is precipitated by cold and wet exposure. Apart from arthralgias, there is no evidence for internal-organ disease or an increased sus- ceptibility to infection. Histological findings include a deep inflammatory infiltrate with perivascular distribution and granular deposits of immunoglobulins and complement along the basement membrane. Some affected individuals show antinuclear antibodies or immune complex formation, whereas cryoglobulins or cold agglutinins are absent. Thus, the findings are consistent with chilblain lupus, a rare form of cutaneous lupus erythematosus. Investigation of a large German kindred with 18 affected members suggests a highly penetrant trait with autosomal dominant inheritance. By single-nucleotide-polymorphism–based genomewide linkage analysis, the locus was mapped to chromosome 3p. Hap- lotype analysis defined the locus to a 13.8-cM interval with a LOD score of 5.04.
