Transmembrane protein 59 (tmem59) is a gene that encodes a protein involved in autophagy and apoptosis in human. A previous study in zebrafish showed that tmem59 mRNA was several folds higher in thrombocytes than those found in red blood cells (RBCs). Therefore, we hypothesized that tmem59 has a role in thrombocytes function. We injected a hybrid of control vivo-morpholino (cVMO) and tmem59 specific antisense standard oligonucleotide (tmem59SO) into adult zebrafish to knockdown tmem59.This piggyback knockdown approach resulted in fish that had more bleeding in gill bleeding assay than the control fish. The thrombocytes fromtmem59 knockdown zebrafish aggregated faster with ADP and collagen agonists. Also, the number of blood cells was reduced after the knockdown of tmem59. We also found the effects of MS-222 anesthesia on hemostasis and found that the bleeding was reduced yielding less blood and the blood cell counts increased probably due to vasoconstriction of the blood vessels. In summary, we found tmem59 is a negative regulator of hemostasis and inferred that anesthesia should be avoided in hemostasis studies.
