Abstract
Pectin is a proven prebiotic and widely used in human health products. This study aims to assess the impact of dietary pectin supplementation during gestation on sow vaginal microbiota and the offspring's intestinal composition. Thirty sows were randomly allocated to two groups and fed a standard diet (CON) or a standard diet supplemented with 3 g/kg pectin (PEC). Blood, feces, and vaginal swab samples from the sows and blood, intestines issue, and colonic content samples from the offspring were collected and analyzed. The results indicate that the relative abundance of vaginal Lactobacillus was notably enhanced in the PEC group and fecal β-glucuronidase (β-G) activity and plasma 17β-estradiol (E2) concentration were also significantly increased in the PEC group. Newborn piglets were found to host different microbial communities as well. At the phylum level, Proteobacteria dominated in the CON group, and Firmicutes was predominant in the PEC group. Newborn piglets in the PEC group had a lower interleukin-6 (IL-6) concentration in their plasma. The expression of intestinal cytokines of offspring was improved as well. Villus height and villus height/crypt depth (V/C) in the PEC group were extremely higher than those in the CON group. In conclusion, dietary pectin supplementation can be of benefit to both sows and newborn piglets.

Newly Obtained Apple Pectin as an Adjunct to Irinotecan Therapy of Colorectal Cancer Reducing E. coli Adherence and β-Glucuronidase Activity. Cancers (Basel) 2021; 13:cancers13122952. [PMID: 34204704 PMCID: PMC8231545 DOI: 10.3390/cancers13122952] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 06/05/2021] [Accepted: 06/09/2021] [Indexed: 02/07/2023] Open
Abstract
Colorectal cancer (CRC) is the second cause of cancer death worldwide. The composition and enzymatic activity of colonic microbiota can significantly affect the effectiveness of CRC chemotherapy. Irinotecan is a drug widely used to treat colon cancer. However, the transformation of a drug-glucuronide (SN-38G) back to its active form (SN-38) by bacterial β-glucuronidase (GUS) constitutes the primary reason for the observed intestinal toxicity of irinotecan. It was demonstrated that novel enzymatically extracted apple pectin (PC) might be a promising candidate for an adjunct to irinotecan therapy. PC itself reduced the viability of HCT 116 and Caco-2 colorectal cancer cells, induced apoptosis, and increased intracellular reactive oxygen species production. Moreover, PC enhanced the cytotoxic and proapoptotic effect of irinotecan (at concentrations below its IC50), i.e., synergistic effect was recorded. Additionally, PC exhibited potent anti-inflammatory properties and prevented adhesion of prototype adherent-invasive E. coli (AIEC) LF82 strain and laboratory K-12C600 strain to colon cancer cells. PC was also identified to be an effective inhibitor of bacterial GUS activity. Altogether, novel apple pectin was identified as a promising candidate for a supplement to irinotecan therapy that might alleviate its side-effects via inhibition of bacterial GUS and thus increasing its therapeutic efficacy.

Abstract
We previously demonstrated that pectin-protein complex (PPC) isolated from white cabbage adsorbs the β-glucuronidase (βG) enzyme of E. coli. Concurrently, we discovered a significant increase in βG activity in the presence of PPC. The aim of this study is to identify the structural components of PPC that are responsible for βG adsorption and activation. PPC was isolated from white cabbage using a saline solution containing hydrochloric acid (pH 1.5) at 37 °C for 4 h. PPC proteins were precipitated by aqueous 10% (m/v) trichloroacetic acid to yield the pectin-protein fractions PPC1 and PPC2. PPC was digested using 1,4-α-d-galacturonase, yielding the PPC6 fraction. Partial acid hydrolysis of PPC revealed the galacturonan fraction, PPC3, to be the core of the macromolecule. The purified PPC4 and PPC5 fractions were isolated from PPC by ion-exchange chromatography on DEAE-cellulose. βG activity and its adsorption in the PPC fractions were studied in vitro. Crystalline cellulose was used as a control. This study found that the PPC3 fraction (the galacturonan core) does not adsorb βG and does not affect its activity. The adsorption of βG in the PPC samples is inversely proportional to the degree of methyl esterification of its carbohydrate component. The PPC4 and PPC5 fractions adsorb the highest proportion of βG (51.2% and 54%, respectively). The stimulation of βG enzyme activity is directly proportional to the protein content of the PPC sample. The PPC and PPC1 samples have the greatest ability to increase βG activity (57.6% and 52.1%, respectively).
