We found and characterized a type D retrovirus produced in a human lymphoblastoid cell line of B-cell lineage. The amino acid sequence of the N-terminal region of the purified major structural protein (PVTRSQGQVSSNTTGRASPHPDTHTIPE) revealed no high homology with any of the known retroviral amino acid sequences. We have cloned cDNA and the proviral genome integrated in the retrovirus-producing cells, and determined the complete nucleotide sequence and gene structures of the genome. The provirus genome is 8785 bp long and has the structure of LTR-gag-prt-pol-eny-LTR. The nucleotide sequences of the long terminal repeat (LTR) region and a part of the pol gene were closely related to the available sequences of squirrel monkey retrovirus (SMRV), and we designated this virus SMRVHLB' abbreviated as SMRV-H. The primer (tRNA(Lys)1,2)-binding sequence of SMRV-H (TGGCGCCCAGGACGTGGGGCTCGA) has a GG insertion, which is different from that of SMRV. The transmembrane protein of the 3' terminal region of env gene contains an amino acid sequence of an immunosuppressive peptide (EVVLQNRRGLDLLTAEQGGICLALQERCCFYANKS), in which R is unique in SMRV-H. The core sequence of the glucocorticoid regulatory element is found upstream of the two 42-bp imperfect repeats in the LTR. Sequences partially homologous to those of the rat IgE-binding protein gene are in gag and pol genes.

The metabolic changes that accompany changes in Cardiopulmonary testing (CPET) and heart failure biomarkers (HFbio) are not well known. We undertook metabolomic and lipidomic phenotyping of a cohort of heart failure (HF) patients and utilized Multiple Regression Analysis (MRA) to identify associations to CPET and HFBio test performance (peak oxygen consumption (Peak VO2), oxygen uptake efficiency slope (OUES), exercise duration, and minute ventilation-carbon dioxide production slope (VE/VCO2 slope), as well as the established HF biomarkers of inflammation C-reactive protein (CRP), beta-galactoside-binding protein (galectin-3), and N-terminal prohormone of brain natriuretic peptide (NT-proBNP)). A cohort of 49 patients with a left ventricular ejection fraction < 50%, predominantly males African American, presenting a high frequency of diabetes, hyperlipidemia, and hypertension were used in the study. MRA revealed that metabolic models for VE/VCO2 and Peak VO2 were the most fitted models, and the highest predictors' coefficients were from Acylcarnitine C18:2, palmitic acid, citric acid, asparagine, and 3-hydroxybutiric acid. Metabolic Pathway Analysis (MetPA) used predictors to identify the most relevant metabolic pathways associated to the study, aminoacyl-tRNA and amino acid biosynthesis, amino acid metabolism, nitrogen metabolism, pantothenate and CoA biosynthesis, sphingolipid and glycerolipid metabolism, fatty acid biosynthesis, glutathione metabolism, and pentose phosphate pathway (PPP). Metabolite Set Enrichment Analysis (MSEA) found associations of our findings with pre-existing biological knowledge from studies of human plasma metabolism as brain dysfunction and enzyme deficiencies associated with lactic acidosis. Our results indicate a profile of oxidative stress, lactic acidosis, and metabolic syndrome coupled with mitochondria dysfunction in patients with HF tests poor performance. The insights resulting from this study coincides with what has previously been discussed in existing literature thereby supporting the validity of our findings while at the same time characterizing the metabolic underpinning of CPET and HFBio.
