Melanoma often recurs after a latency period of several years, presenting T cell-edited phenotype that reflects role for CD8(+) cells in maintaining metastatic latency. Here, we report an investigation patient with multiple recurrent lesions, where poorly immunogenic melanoma phenotypes were found to evolve the presence autologous tumor antigen-specific cells. from two three late metastases, developing within 6-year period, lacked HLA class I expression. cell-resistant, I-negative became...
Lichens are valuable models in symbiosis research and promising sources of biosynthetic genes for biotechnological applications. Most lichenized fungi grow slowly, resist aposymbiotic cultivation, poor candidates experimentation. Obtaining contiguous, high-quality genomes such symbiotic communities is technically challenging. Here, we present the first assembly a lichen holo-genome from metagenomic whole-genome shotgun data comprising both PacBio long reads Illumina short reads. The nuclear...
In the subterranean rodent (Nanno)spalax galili, evolutionary adaptation to hypoxia is correlated with longevity and tumor resistance. Adapted gene-regulatory networks of Spalax might pinpoint strategies maintain health in humans. Comparing liver, kidney spleen transcriptome data from rat at normoxia, we identified differentially expressed gene pathways common multiple organs both species. Body-wide interspecies differences affected processes like cell death, antioxidant defense, DNA repair,...
Recently, immunohistochemical analysis of myoglobin (MB) in human breast cancer specimens has revealed a surprisingly widespread expression MB this nonmuscle context. The positive correlation with hypoxia-inducible factor 2α (HIF-2α) and carbonic anhydrase IX suggested that oxygen regulates carcinomas. Here, we report mRNA protein levels are robustly induced by prolonged hypoxia cell lines, part via HIF-1/2-dependent transactivation. hypoxia-induced originated from novel alternative...
Abstract The blind subterranean mole rat Spalax shows a remarkable tolerance to hypoxia, cancer-resistance and longevity. Unravelling the genomic basis of these adaptations will be important for biomedical applications. RNA-Seq gene expression data were obtained from normoxic hypoxic liver tissue. Hypoxic broadly downregulates genes major function pathways. This energy-saving response is likely crucial adaptation low oxygen levels. In contrast, hypoxia-sensitive massive upregulation energy...

Myoglobin (MB) is not only strongly expressed in myocytes, but also at much lower levels different cancer entities. 40% of breast tumors are MB-positive, with the globin being co-expressed markers tumor hypoxia a proportion cases. In cancer, MB expression associated positive hormone receptor status and patient prognosis. prostate another hormone-dependent type, 53% were recently shown to express MB. Especially more aggressive specimen correlates increased survival rates. Both findings might...
The identification of novel physiological regulators that stimulate energy expenditure through brown adipose tissue (BAT) activity in substrate catalysis is utmost importance to understand and treat metabolic diseases. Myoglobin (MB), known store or transport oxygen heart skeletal muscles, has recently been found bind fatty acids with constants its oxygenated form (i.e., MBO2). Here, we investigated the vivo effect MB expression on BAT activity. In particular, studied mitochondrial function...
Myoglobin (MB) is an oxygen-binding protein usually found in cardiac myocytes and skeletal muscle fibers. It may function as a temporary storage transport for O 2 but could also have scavenging capacity reactive oxygen nitrogen species. In addition, MB has recently been identified hallmark luminal breast cancer was shown to be robustly induced under hypoxia. Cellular responses hypoxia are regulated by the transcription factor hypoxia-inducible (HIF). For exploring of cancer, we employed...
Recently, the ectopic expression of myoglobin (MB) was reported in human epithelial cancer cell lines and breast tumor tissues, where MB increased with hypoxia. The better prognosis MB-positive patients suggested that globin exerts a tumor-suppressive role, possibly by impairing mitochondrial activity hypoxic carcinoma cells. To understand gene regulation cancer, we systematically investigated architecture gene, its transcripts promoters. In silico analysis transcriptome data from normal...
Myoglobin (MB) is known to bind and deliver oxygen in striated muscles at high expression levels. MB also expressed much reduced levels mammary epithelial cells, where the protein´s function unclear. In this study, we aim determine whether impacts fatty acid trafficking facilitates aerobic ß-oxidation cells.

Ectopic myoglobin (MB) expression, mediated by alternative and hypoxia-inducible transcription, has recently been demonstrated in several epithelial tumours. This study aimed to examine the expression of MB hormone-independent head neck squamous cell carcinomas (HNSCCs).Using imunohistochemistry, ectopic was analyzed on tissue microarrays (TMAs) 524 patients with localized locally advanced primary recurrent HNSCC who had undergone surgical treatment curative intent. Associations survival...
The muscle‑associated respiratory protein myoglobin (MB) is expressed in multiple types of cancer, including breast and prostate tumors. In Kaplan‑Meier analyses the two tumor types, MB positivity associated with favorable prognoses. Despite its well‑characterized function myocytes, role cancer remains unclear. To study impact endogenous expression, small interfering RNA MB‑knockdown cells were engineered using breast, colon cell lines (MDA‑MB468, LNCaP, DLD‑1), their transcriptomes...
