background: interfering with cell proliferation and survival is a critical role for antineoplastic drugs leading to cell death through induction of apoptosis. alternative treatments with herbal extracts offer insights into acute myeloid leukemia (aml) therapy. parthenolide (ptl), an extract from feverfew, induces apoptosis in primary human leukemia stem cells (lscs) and bulk leukemic cell popul...

Cancer is one of the main causes of mortality. Therapeutic importance in some diseases, especially cancers has led to considering the anti-cancer effects of probiotics more than ever. Probiotics have stimulatory effects on the immunity and suppressor effects on cancer activity. Various studies report that probiotic bacteria have cytotoxicity effects on different types of solid tumors. In this r...

JC polyomavirus (JCV), the causative agent of progressive multifocal leukoencephalopathy (PML), is ubiquitous in humans, infecting children asymptomatically and then persisting in the kidney. Renal JCV is not latent but replicates to excrete progeny in the urine. The renal-urinary JCV DNAs carry the archetype regulatory region that generates various rearranged regulatory regions occurring in JC...

interferon gamma (ifn-γ) is one of the key cytokines in defining t helper 1 lymphocyte immuneresponses. in this study, the bovine ifn-γ gene was cloned from spleen tissue rna using the reversetranscription-polymerase chain reaction (rt-pcr). ifn-γ cdna was sub-cloned and expressed inmammalian expression plasmid (pcdna3.1(+)) under the control of the human cytomegalovirus (cmv)promoter. the pred...

We have isolated the human homologue of the murine erythropoietin receptor (mEPO-R) from an erythroleukemia line, OCIM1, and from fetal liver. Both the cDNA and protein sequence of the human receptor were 82% homologous to the mEPO-R. Heterologous expression of the human cDNA in COS cells yielded a protein of about 66 Kd. The protein could be specifically immunoprecipitated with either an antib...

Apoptotic cell shrinkage, an early hallmark of apoptosis, is regulated by K+ efflux and K+ channel activity. Inhibited apoptosis and downregulated K+ channels in pulmonary artery smooth muscle cells (PASMC) have been implicated in development of pulmonary vascular medial hypertrophy and pulmonary hypertension. The objective of this study was to test the hypothesis that overexpression of KCNA5, ...
