Berberine suppresses migration of MCF-7 breast cancer cells through down-regulation of chemokine receptors
Objective(s): Berberine is one of the main alkaloids and it has been proven to have different pharmacological effects including inhibition of cell cycle and progression of apoptosis in various cancerous cells; however, its effects on cancer metastasis are not well known. Cancer cells obtain the ability to change their chemokine system and convert into metastatic cells. In this study, we examine...
متن کاملCCR1 (chemokine (C-C motif) receptor 1)
Note CCR1, a member of the beta chemokine receptor family, is a seven transmembrane protein similar to G protein-coupled receptors. CCR1 is the first human CC chemokine receptor to be identified at the cDNA level. It has a functional viral homolog, US28, which is a human cytomegalovirus.The ligands of this receptor include macrophage inflammatory protein 1 alpha (MIP-1 alpha), regulated on acti...
متن کاملHuman herpesvirus 6 open reading frame U12 encodes a functional beta-chemokine receptor.
Human herpesvirus 6 (HHV- 6), which belongs to the betaherpesvirus subfamily and infects mainly T cells in vitro, causes acute and latent infections. HHV- 6 contains two genes (U12 and U51) that encode putative homologs of cellular G-protein-coupled receptors (GCR), while three other betaherpesviruses, human cytomegalovirus, murine cytomegalovirus, and human herpesvirus 7, have three, one, and ...
متن کاملHuman cytomegalovirus inhibits the migration of immature dendritic cells by down-regulating cell-surface CCR1 and CCR5.
Dendritic cells (DC) play a key role in the host immune response to infections. Human cytomegalovirus (HCMV) infection can inhibit the maturation of DC and impair their ability to stimulate T cell proliferation and cytotoxicity. In this study, we assessed the effects of HCMV infection on the migratory behavior of human DC. The HCMV strain TB40/E inhibited the migration of immature monocyte-deri...
متن کاملBacterial superantigens induce down-modulation of CC chemokine responsiveness in human monocytes via an alternative chemokine ligand-independent mechanism.
Staphylococcal superantigens (SAgs) are very potent T cell mitogens, but they can also activate monocytes by binding directly to MHC class II molecules in a manner independent of TCR coengagement. Induction of proinflammatory cytokines and chemokine expression in monocytes by superantigens has recently been reported. Here we report that superantigen stimulation of human peripheral blood monocyt...
