Anti-colorectal cancer actions of Glycyrrhiza uralensis Fisch. and its underlying mechanism via HPLC integration and network pharmacological approaches.

Background: The therapeutic and prognostic outcomes for colorectal cancer (CRC) remain unsatisfactory. Among multiple reported bioactive functionalities of Glycyrrhiza uralensis Fisch. one vital recently reported activity is its therapeutic role against numerous cancers but limited information is available related to its underlying key mechanisms and therapeutically active ingredients, especially against CRC treatment.

Amelioration of collagen-induced arthritis using antigen-loaded dendritic cells modified with NF-κB decoy oligodeoxynucleotides.

Dendritic cells (DCs) play an important role in the initiation of autoimmunity in rheumatoid arthritis (RA); therefore, the use of DCs needs to be explored to develop new therapeutic approaches for RA. Here, we investigated the therapeutic effect of bovine type II collagen (BIIC)-loaded DCs modified with NF-κB decoy oligodeoxynucleotides (ODNs) on collagen-induced arthritis (CIA) in rats and explored the underlying mechanisms. DCs treated with BIIC and NF-κB decoy ODNs exhibited features of immature DCs with low levels of costimulatory molecule (CD80 and CD86) expression.

Construction and evaluation of rats' tolerogenic dendritic cells (DC) induced by NF-κB Decoy method.

Aims: To construct and evaluate rats' tolerogenic dendritic cells (DC) through induction by NF-κB Decoy method.

Methods: GM-CSF and IL-4 were used to transform rats's monocytes into DC, and DC were stimulated with LPS, NF-κB Decoy ODN, and loaded with Bovine Type II Collagen. The following methods were employed to phenotype DC: 1) Observation of cell morphology; 2) Evaluation of cell viability using trypan blue staining; 3) Purity determination of DC through detection of specific markers OX-62; 4) Evaluation of mature state of DC via the determination of the expression of CD80 and CD86; 5) Determination of stimulation capability towards the proliferation of lymphocyte and the secretion of INF-r and IL-10.
