Acute Effects of the Consumption of Passiflora setacea Juice on Metabolic Risk Factors and Gene Expression Profile in Humans

Background: Passiflora setacea (PS) is a passionfruit variety of the Brazilian savannah and is a rich source of plant food bioactives with potential anti-inflammatory activity. This study aimed to investigate the effect of an acute intake of PS juice upon inflammation, metabolic parameters, and gene expression on circulating immune cells in humans. Methods: Overweight male volunteers (n = 12) were enrolled in two double-blind placebo-controlled studies. Blood samples were collected from fasting volunteers 3 h after the consumption of 250 mL of PS juice or placebo (PB). Metabolic parameters (insulin, glucose, total cholesterol, high-density lipoprotein (LDL), high-density lipoprotein (HDL), and total triglycerides) and circulating cytokines were evaluated (study 1). Peripheral blood mononuclear cell (PBMC) from the same subjects were isolated and RNA was extracted for transcriptomic analyses using microarrays (study 2). Results: Insulin and homeostatic model assessment for insulin resistance (HOMA-IR) levels decreased statistically after the PS juice intake, whereas HDL level increased significantly. Interleukin (IL)-17A level increased after placebo consumption, whereas its level remained unchanged after PS juice consumption. Nutrigenomic analyses revealed 1327 differentially expressed genes after PS consumption, with modulated genes involved in processes such as inflammation, cell adhesion, or cytokine–cytokine receptor. Conclusion: Taken together, these clinical results support the hypothesis that PS consumption may help the prevention of cardiometabolic diseases.

The effects of Ciji-Hua'ai-Baosheng on immune function of mice with H22 hepatocellular carcinoma receiving chemotherapy

BACKGROUND

Ciji-Hua'ai-Baosheng Decoction (CHBD) is a traditional Chinese formula that may attenuate the toxicity and side-effects of chemotherapy. The formula may also prolong the life of cancer patients. Whether CHBD should be employed as adjunctive therapy for cancer patients receiving chemotherapy has yet to be determined as does the mechanism whereby CHBD exerts its beneficial effects.

AIM OF THE STUDY

To document the potential effects of CHBD on tumor growth and immune function in a murine model of hepatocellular carcinoma (HCC) receiving chemotherapy.

MATERIALS AND METHODS

Sixty Kunming mice were injected subcutaneously with H₂₂ hepatoma cells in the right anterior armpit. After seven days, the mice with formed tumors were injected with Cytoxan (CTX) (200 mg/kg) to establish the chemotherapy model. These mice were randomly divided into 5 groups: model (untreated controls), control (CTX,33.33 mg/kg), and high CHBD (H) (117 g/kg), moderate CHBD (M) (58.5 g/kg) and low CHBD (L) (29.25 g/kg) treated groups. Tumor weights and inhibitory ratio (decrease in tumor dimensions), histology of tumor, colon, spleen and liver, and biochemical tests of liver and kidney function were documented after 10 days. Serum and tumor IL-2, IFN-γ, IL-6, and TNF-α levels were determined by enzyme-linked immunosorbent assay (ELISA) and Western blot respectively. The potential bioactive compounds in CHBD were characterized by UHPLC-MS.

RESULTS

Although tumor weights were decreased in CTX alone and CHBD (H) and CHBD (M) groups (-66%, -41% and -25% respectively), tumor cell density was reduced to the greatest extent in the CHBD (H) group. CHBD had no evident effects on liver and kidney function. CTX-induced colon inflammation and decrease in spleen lymphocytes were attenuated with CHBD treatment. CHBD increased serum IL-2, IFN-γ and TNF-α, but decreased IL-6 levels in serum and tumor tissue. UHPLC-MS analysis of CHBD revealed the presence of 11 bioactive compounds.

CONCLUSIONS

In this murine model of HCC receiving chemotherapy, CHBD inhibited tumor growth, improved immune function and pro-inflammatory cytokine responses while attenuating CTX-associated side effects.
