Effects of Curcumin in Free and Phytosomal Forms on the Expression of T Helper1 and Regulatory T Cells' Transcription Factors in Collagen-Induced Arthritis.

Background: Curcumin as a polyphenolic compound has a potential capacity to reduce autoimmune reactions by skewing the balance of Thelper1 (Th1)/regulatory T cells (Treg) toward Treg cells. However, the low absorption and bioavailability of this agent have prompted researchers to use various drug delivery systems such as phytosomes to reduce these drawbacks. To date, few studies have evaluated the effects of phytosomal curcumin (nano-curcumin) on immune responses.

Apelin receptor antagonist boosts dendritic cell vaccine efficacy in controlling angiogenic, metastatic and apoptotic-related factors in 4T1 breast tumor-bearing mice.

Apelin/APJ axis plays a critical role in cancer progression, thus its targeting inhibits tumor growth. However, blocking of Apelin/APJ axis in combination with immunotherapeutic approaches may be more effective. This study aimed to investigate the effects of APJ antagonist ML221 in combination with a DC vaccine on angiogenic, metastatic and apoptotic-related factors in a breast cancer (BC) model.

Effects of nisin on the expression of virulence genes of methicillin-resistant/sensitive .

Background And Objectives: Few studies have considered potential benefits of probiotic bacteria and their derivatives on human and animal health. Nisin is an antimicrobial agent that is produced by lactobacilli and served as a preservative in foods. This study aims to investigate whether nisin suppresses or decreases the genes involved in the pathogenicity of methicillin-susceptible and methicillin-resistant (MSSA and MRSA).

The New Compound of (2R, 4S)-N-(2, 5-difluorophenyl)-4-Hydroxy-1-(2, 2, 2-Trifluoroacetyl) Pyrrolidine-2-Carboxamide to Mediate the Expression of Some Apoptosis Genes by the HepG2 Cell Line.

Objectives: Hepatocellular carcinoma is one of the most frequent cancers worldwide, for the treatment of which various therapy protocols and drugs have been introduced; however, none of them has suppressed cancer tissues completely. New research programs have been developed on cancer and the accompanied effects of novel synthesized compounds on cancer cell lines. Our latest reports on the molecular basis of cancer revealed a pattern of changes in gene expression triggered in the cancer pathway.

Demethoxycurcumin: A naturally occurring curcumin analogue with antitumor properties.

The eradication of cancer in a patient remains an elusive challenge despite advances in early detection and diagnosis, chemo- and immunotherapy, pinpoint radiation treatments, and expert surgical intervention. Although significant gains have been made in our understanding of cancer cell biology, a definite cure for most cancers does not exist at present. Thus, it is not surprising that the research and medical communities continue to explore the importance and therapeutic potential of natural products in their multimodality cancer treatment approach.
