Excess of retrogene traffic in pig X chromosome.

Genetica 2018 Dec 10. Epub 2018 Dec 10.

Key Laboratory of Agricultural Animal Genetics, Breeding and Reproduction, Ministry of Education, College of Animal Science and Veterinary Medicine, Huazhong Agricultural University, Wuhan, 430070, People's Republic of China.

Despite the insights into retrogene evolution in multiple species provided by trans-traffic retrogenes (trans-retrogenes), cis-traffic retrogenes (cis-retrogenes) are hitherto understudied and thus limit our understanding of genetic novelty. Here we used the pig genome as a model to compare cis- and trans-retrogenes. We found that cis- and trans-retrogenes have similar patterns in terms of excessive X-chromosome representation, testis expression preference, and metabolic functional enrichment. Read More

RNA-on-X 1 and 2 in Drosophila melanogaster fulfill separate functions in dosage compensation.

PLoS Genet 2018 Dec 10;14(12):e1007842. Epub 2018 Dec 10.

Department of Molecular Biology, Umeå University, Umeå, Sweden.

In Drosophila melanogaster, the male-specific lethal (MSL) complex plays a key role in dosage compensation by stimulating expression of male X-chromosome genes. It consists of MSL proteins and two long noncoding RNAs, roX1 and roX2, that are required for spreading of the complex on the chromosome and are redundant in the sense that loss of either does not affect male viability. However, despite rapid evolution, both roX species are present in diverse Drosophilidae species, raising doubts about their full functional redundancy. Read More

Anti-leukemia immunity plays an important role in disease control and maintenance of tyrosine kinase inhibitor (TKI)-free remission in chronic myeloid leukemia (CML). Thus, antigen-specific immunotherapy holds promise to strengthen immune control in CML, but requires the identification of CML-associated targets. In this study, we used a mass spectrometry-based approach to identify naturally presented, HLA class I- and class II-restricted peptides in primary CML samples. Read More

Teratomas are tumors consisting of components of the three germ layers that differentiate from pluripotent stem cells derived from germ cells. In the normal mouse testis, teratomas rarely form, but a deficiency in Dead-end1 (Dnd1) in mice with a 129/Sv genetic background greatly enhances teratoma formation. Thus, DND1 is crucial for suppression of teratoma development from germ cells. Read More

Brucella canis infection in a young dog with epididymitis and orchitis.

Schweiz Arch Tierheilkd 2018 Dec;160(12):743-748

Institute of Veterinary Bacteriology, Vetsuisse Faculty, University of Zurich.

Introduction: The following case report describes the clinical and diagnostic procedure for suspected brucellosis infection in a dog. A 21 month old intact male Border Collie was presented with an enlarged right testicle and epididymis. The dog was imported to Switzerland from Germany at the age of three months, but was never abroad since then. Read More

Attaining threshold antibody cytotoxicity for selective tumor cell destruction: an opinion article.

Oncotarget 2018 Nov 6;9(87):35790-35794. Epub 2018 Nov 6.

Institute for Fundamental and Clinical Immunology, Novosibirsk, Russia.

We propose a novel immunotherapeutic paradigm that justifies application of several antibodies to various membrane-associated antigens to achieve a critical threshold density of immune complexes on the surface of cancer cells sufficient for triggering downstream cytolytic pathways. Indeed, some cancer-associated antigens (such as cancer/testis antigens) were found to be expressed on many cancer (but not normal) cells, with their baseline membrane expression levels being originally quite low for some of them, or even further down-regulated due to immune-driven cell selection. To achieve the mandatory threshold density of membrane-associated immune complexes on malignant cells, the concept stipulates combined application of antibodies specific for a cancer-associated antigen along with antibodies against an antigen expressed not only on tumor, but also on normal cells.

Investigation of the Developmental Requirements of Drosophila HP1 and Insulator Protein Partner, HIPP1.

G3 (Bethesda) 2018 Dec 4. Epub 2018 Dec 4.

Drosophila Suppressor of Hairy-wing [Su(Hw)] is a multifunctional zinc finger DNA binding protein. Transcriptional regulation by Su(Hw) is essential in the ovary and testis, where Su(Hw) functions primarily as a repressor. Recently, the HP1a and Insulator Partner Protein 1 (HIPP1) was found to extensively co-localize with Su(Hw) and other insulator binding proteins in euchromatic regions of the genome, and with Heterochromatin Protein 1a (HP1a) in heterochromatic regions.

Persistence and Sexual Transmission of Filoviruses.

Viruses 2018 Dec 2;10(12). Epub 2018 Dec 2.

Laboratory of Emerging and Re-Emerging Viruses, Department of Medical Microbiology and Infectious Diseases, University of Manitoba, Winnipeg, MB R3E 0J9, Canada.

There is an increasing frequency of reports regarding the persistence of the Ebola virus (EBOV) in Ebola virus disease (EVD) survivors. During the 2014⁻2016 West African EVD epidemic, sporadic transmission events resulted in the initiation of new chains of human-to-human transmission. Multiple reports strongly suggest that these re-emergences were linked to persistent EBOV infections and included sexual transmission from EVD survivors. Read More

Solitary Bone Metastasis as the First Presentation of Germ Cell Testicular Cancer Treated with Internal Hemipelvectomy: A Case Report.

Urol Int 2018 Dec 4:1-4. Epub 2018 Dec 4.

Department of Pelvic Surgery, A.C. Camargo Cancer Center, São Paulo, Brazil.

Solitary bone metastasis from testicular tumor is rare. In literature, only few cases of isolated bone metastasis at first presentation have been reported, and none of them have been treated with extended surgery of the pelvic bone. Case Presentation: We report the case of a 33-year-old man with an iliac bone osteolytic metastasis as the first presentation of a non-seminomatous germ-cell testis tumor (NSGCT), treated with post-chemotherapy en bloc resection of residual tumor in the left iliac bone (Type I + II internal hemipelvectomy).

Behavioral consequences of dietary exposure to crude oil extracts in the Siamese fighting fish (Betta splendens).

Aquat Toxicol 2018 Nov 29;207:34-42. Epub 2018 Nov 29.

Developmental Integrative Biology Research Group, Department of Biological Sciences, University of North Texas,1155 Union Circle #305220, Denton, TX, 76203-5017, USA.

Uptake by fishes of crude oil and its polycyclic aromatic hydrocarbons (PAHs) components occurs via gills, dietary intake, or diffusion through the skin. Dietary exposure to crude oil and its components is environmentally relevant, and induces physiological and morphological disruptions in fish. However, the impacts of crude oil on fish social and reproductive behaviors and thus the possible influences on reproductive success are poorly understood. Read More
