The human V-preB promoter is a target for coordinated activation by early B cell factor and E47.

Factor and E47 Coordinated Activation by Early B Cell the Human V-preb Promoter Is a Target For

B and T Lymphocyte Attenuator is a Target of miR-155 during Naive CD4+ T Cell Activation

Background: MicroRNA-155 (miR-155) is upregulated during T cell activation, but the exact mechanisms by which it influences CD4+ T cell activation remain unclear. Objective: To examine whether the B and T lymphocyte attenuator (BTLA) is a target of miR-155 during naïve CD4+ T cell activation. Methods: Firefly luciferase reporter plasmids pEZX-MT01-wild-type-BTLA and pEZX-MT01-mutant-BTLA were ...

Inhibition of p300/CBP by early B-cell factor.

Early B-cell factor (EBF) is a DNA binding protein required for early B-cell development. It activates transcription of several B-cell-specific genes, including the lambda5 gene, which encodes a protein necessary for signaling by the pre-B-cell receptor. In an effort to understand the mechanism by which EBF activates transcription, we examined its interaction with the coactivator protein p300/C...

اثر سینرژیستی ایندول تری کربینول با دوکسوروبیسین در افزایش القای آپوپتوز بر رده سلولی لوسمی لنفوبلاستیک حاد (NALM-6)

Background and Aim: Indole-3-carbinol (I3C), found in Brassica species vegetables, exhibits antitumor effects. It has been shown that I3C induces apoptosis in various cell types through inactivation of the nuclear factor-kappa B (NF- k B) pathway. Anthracyclines such as doxorubicin, is widely used in the treatment of hematological malignancies, induce apoptosis in tumor cells via DNA damage and...

IMMUNOBIOLOGY E47, IRF-4, and PU.1 synergize to induce B-cell–specific activation of the class II transactivator promoter III (CIITA-PIII)

In B cells, expression of CIITA and resulting major histocompatibility complex II (MHCII) is mediated exclusively by promoter III (CIITA-PIII) activation. Recent studies have established that CIITA-PIII also participates in the expression of CIITA in activated human T cells, dendritic cells, and monocytes. In this study we characterized the various regulatory elements and interacting factors of...
