The current study aimed to investigate the effect of a multi-species probiotic (MSP) on cytokine production by human peripheral blood mononuclear cells (PBMCs) and their immune dialogue with HT-29 colon cancer cells. PBMCs were incubated with MSP and their effect on cell proliferation and TNFα, IL-1β, IL-2, IL-6, IFNγ, IL-10, and IL-1ra production was evaluated. The impact of MSP on the cytokine production by PBMC stimulated by HT-29 cells was detected. Not-stimulated PBMC incubated with MSP showed increased production of TNFα, IL-1β, IL-6, and IL-10, but no change in IL-6, IFNγ, and IL-1ra. The stimulatory effect of MSP on lipopolysaccharide (LPS)-promoted PBMC was less pronounced for TNFα, IL-1β, and IFNγ, and the IL-6 production was decreased; phorbol 12-myristate 13- acetate (PMA)-induced IL-2 and IFNγ secretion was inhibited. The addition of MSP to co-cultures of PBMC and HT-29 cancer cells caused a remarkable increase in TNFα and IL-1β secretion, with no change in remaining cytokines. The multi-species probiotics modulated cytokine production by PBMC and affected the cross-talk between PBMC and HT-29 cancer cells. We conclude that probiotics may serve as supplements to the therapeutic strategies applied for the treatment of chronic inflammatory and malignant diseases, especially colorectal cancers.

In this work, we sought to investigate the effects of a thiosulfinate-enriched garlic extract, co-administered with 5-fluorouracil (5-FU) or oxaliplatin chemotherapy, on the viability of colon cancer cells (Caco-2 and HT-29). We also addressed the economic feasibility of a new combined treatment of this thiosulfinate-enriched garlic extract, with oxaliplatin that could reduce the dosage and costs of a monotherapy. The thiosulfinate-enriched garlic extract not only enhanced the impact of 5-FU and oxaliplatin (500 µM) in decreasing Caco-2 and HT-29 viability, but also showed a higher effect than standard 5-FU and oxaliplatin chemotherapy as anti-cancer agents. These results provided evidences for the combination of lyophilized garlic extract and 5-FU or oxaliplatin as a novel chemotherapy regimen in colon cancer cells that may also reduce the clinical therapy costs.

(1) Background: Cynara cardunculus L. subsp. scolymus (L.) Hegi, popularly known as artichoke, is an herbaceous plant belonging to the Asteraceae family. Artichoke leaf extracts (ALEs) have been widely used in traditional medicine because of their hepatoprotective, cholagogic, hypoglycaemic, hypolipemic and antibacterial properties. ALEs are also recognized for their antioxidative and anti-inflammatory activities. In this study, we evaluated the cytotoxic, genotoxic, and apoptotic activities, as well as effect on cell growth of ALEs on human colon cancer HT-29 and RKO cells. HT-29 and RKO cells exhibit a different p53 status: RKO cells express the wild-type protein, whereas HT-29 cells express a p53-R273H contact mutant. (2) Methods: Four different ALEs were obtained by sequential extraction of dried artichoke leaves; ALEs were characterized for their content in chlorogenic acid, cynaropicrin, and caffeoylquinic acids. HT-29 and RKO cells were used for in vitro testing (i.e., cytotoxicity and genotoxicity assessment, cell cycle analysis, apoptosis induction). (3) Results: Two out of the four tested ALEs showed marked effects on cell vitality toward HT-29 and RKO tumour cells. The effect was accompanied by a genotoxic activity exerted at a non-cytotoxic concentrations, by a significant perturbation of cell cycle (i.e., with increase of cells in the sub-G1 phase), and by the induction of apoptosis. (4) Conclusions: ALEs rich in cynaropicrin, caffeoylquinic acids, and chlorogenic acid showed to be capable of affecting HT-29 and RKO colon cancer cells by inducing favourable biological effects: cell cycle perturbation, activation of mitochondrial dependent pathway of apoptosis, and the induction of genotoxic effects probably mediated by the induction of apoptosis. Taken together, these results weigh in favour of a potential cancer chemotherapeutic activity of ALEs.
