To investigate the pattern of human ERMAP gene expression in different cell lines, 15 cell lines derived from hematopoietic tumor, somatic tumor and normal tissue were chosen and were cultured; cells were harvested after culture for 12, 24, 36, 48, 60 and 72 hours; the expression of the human ERMAP was detected by using fluorescent quantitative PCR. The results showed that human ERMAP gene expression was positive in K562 cell line at interval of 12 and 24 hours, and the expression levels were (5.092 +/- 2.331) x 10(6) cps/microl RNA, (5.328 +/- 3.916) x 10(6) cps/microl RNA, respectively; ERMAP gene expression was also positive in ECV304 cell line at interval of 24 hours, and the expression level was (0.84 +/- 0.12) x 10(6) cps/microl RNA; and its expression was negative in other 13 cell lines. It is concluded that human ERMAP gene expression in ECV304 cell line was found first, and its expression in K562 cell line was further confirmed.

Background: Sodium-glucose cotransporter 2 (SGLT2) inhibitors exert a distinctive pattern of direct biological effects on the heart and kidney under experimental conditions, but the meaningfulness of these signatures for patients with heart failure has not been fully defined.
Objectives: We performed the first mechanistic validation study of large-scale proteomics in a double-blind randomized trial of any treatment in patients with heart failure.
Methods: In a discovery cohort from the EMPEROR (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure and Reduced Ejection Fraction) program, we studied the effect of randomized treatment with placebo or empagliflozin on 1,283 circulating proteins in 1,134 patients with heart failure with a reduced or preserved ejection fraction.

The emerging malaria parasite Plasmodium knowlesi threatens the goal of worldwide malaria elimination due to its zoonotic spread in Southeast Asia. After brief ex-vivo culture we used 2D LC/MS/MS to examine the early and late ring stages of infected Macaca mulatta red blood cells harboring P. knowlesi.

Kupffer cells, the liver tissue resident macrophages, are critical in the detection and clearance of cancer cells. However, the molecular mechanisms underlying their detection and phagocytosis of cancer cells are still unclear. Using in vivo genome-wide CRISPR-Cas9 knockout screening, we found that the cell-surface transmembrane protein ERMAP expressed on various cancer cells signaled to activate phagocytosis in Kupffer cells and to control of liver metastasis.

Background: Scianna (Sc) antigens, seven high and two of low prevalence, are expressed on erythrocyte membrane-associated protein (ERMAP). We investigated SC (ERMAP) in individuals who made antibodies to high prevalence Scianna antigens, and propose a 3D model for ERMAP to precisely localize the residues associated with the known antigens.
Methods: Serological testing and DNA sequencing was performed by standard methods.
