Abstract
Cancer remains a multifactorial disease with an increased mortality rate around the world for the past several decades. Despite advancements in treatment strategies, lower survival rates, drug-associated side effects, and drug resistance create a need for novel anticancer agents. Ample evidence shows that imbalances in the gut microbiota are associated with the formation of cancer and its progression. Altering the gut microbiota via probiotics and their metabolites has gained attention among the research community as an alternative therapy to treat cancer. Probiotics exhibit health benefits as well as modulate the immunological and cellular responses in the host. Apart from probiotics, their secreted products like bacteriocins, exopolysaccharides, short-chain fatty acids, conjugated linoleic acid, peptidoglycan, and other metabolites are found to possess anticancer activity. The beneficiary role of these postbiotic compounds is widely studied for characterizing their mechanism and mode of action that reduces cancer growth. The present review mainly focuses on the postbiotic components that are employed against cancer with their reported mechanism of action. It also describes recent research works carried out so far with specific strain and anticancer activity of derived compounds both in vitro and in vivo, validating that the probiotic approach would pave an alternative way to reduce the burden of cancer.

Front Microbiol 2023; 14:1276268. [PMID: 37840711 PMCID: PMC10569472 DOI: 10.3389/fmicb.2023.1276268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Accepted: 09/11/2023] [Indexed: 10/17/2023] Open
Abstract
This study aimed to examine the effects of supplementation of postbiotics derived from Streptococcus thermophilus (ST) and Lactobacillus delbrueckii subsp. bulgaricus (LB) in cheese whey (CW) and skim milk (SM) on antioxidant activity, viability of yoghurt starters, and quality parameters of low-fat yoghurt during 22 days of storage. The LB-CW (L delbrueckii ssp. bulgaricus postbiotic-containing cheese whey) sample exhibited the highest antioxidant activity, with 18.71% inhibition (p > 0.05). This sample also showed the highest water holding capacity (77.93%; p < 0.05) and a trend toward receiving the most favorable sensory attributes (p > 0.05) compared to the other samples. The LB-CW and LB-SM yoghurt samples exhibited significantly higher body and texture scores compared to the ST-SM-fortified yoghurt (p < 0.05). However, there was no significant difference in the overall acceptability of the LB-SM and ST-SM yoghurt samples across both starters (p > 0.05). Such findings highlight the potential of postbiotics as functional ingredients to enhance the nutritional and sensory aspects of yoghurt, further contributing to its appeal as a health-promoting product.

Appraisal of the Possible Role of PPAR γ Upregulation by CLA of Probiotic Pediococcus pentosaceus GS4 in Colon Cancer Mitigation. PPAR Res 2023; 2023:9458308. [PMID: 36875279 PMCID: PMC9984262 DOI: 10.1155/2023/9458308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 01/21/2023] [Accepted: 02/02/2023] [Indexed: 03/07/2023] Open
Abstract
The prevalence of colon cancer (CC) is increasing at the endemic scale, which is accompanied by subsequent morbidity and mortality. Although there have been noteworthy achievements in the therapeutic strategies in recent years, the treatment of patients with CC remains a formidable task. The current study focused on to study role of biohydrogenation-derived conjugated linoleic acid (CLA) of probiotic Pediococcus pentosaceus GS4 (CLAGS4) against CC, which induced peroxisome proliferator-activated receptor gamma (PPARγ) expression in human CC HCT-116 cells. Pre-treatment with PPARγ antagonist bisphenol A diglycidyl ether has significantly reduced the inhibitory efficacy of enhanced cell viability of HCT-116 cells, suggesting the PPARγ-dependent cell death. The cancer cells treated with CLA/CLAGS4 demonstrated the reduced level of Prostaglandin E2 PGE2 in association with reduced COX-2 and 5-LOX expressions. Moreover, these consequences were found to be associated with PPARγ-dependent. Furthermore, delineation of mitochondrial dependent apoptosis with the help of molecular docking LigPlot analysis showed that CLA can bind with hexokinase-II (hHK-II) (highly expressed in cancer cells) and that this association underlies voltage dependent anionic channel to open, thereby causing mitochondrial membrane depolarization, a condition that initiates intrinsic apoptotic events. Apoptosis was further confirmed by annexin V staining and elevation of caspase 1p10 expression. Taken all together, it is deduced that, mechanistically, the upregulation of PPARγ by CLAGS4 of P. pentosaceus GS4 can alter cancer cell metabolism in association with triggering apoptosis in CC.

Abstract
Background Pediococcus pentosaceus, a promising strain of lactic acid bacteria (LAB), is gradually attracting attention, leading to a rapid increase in experimental research. Due to increased demand for practical applications of microbes, the functional and harmless P. pentosaceus might be a worthwhile LAB strain for both the food industry and biological applications. Results As an additive, P. pentosaceus improves the taste and nutrition of food, as well as the storage of animal products. Moreover, the antimicrobial abilities of Pediococcus strains are being highlighted. Evidence suggests that bacteriocins or bacteriocin-like substances (BLISs) produced by P. pentosaceus play effective antibacterial roles in the microbial ecosystem. In addition, various strains of P. pentosaceus have been highlighted for probiotic use due to their anti-inflammation, anticancer, antioxidant, detoxification, and lipid-lowering abilities. Conclusions Therefore, it is necessary to continue studying P. pentosaceus for further use. Thorough study of several P. pentosaceus strains should clarify the benefits and drawbacks in the future.

Abstract
The current study examined the cell adherence property of probiotic Pediococcus pentosaceus GS4 (MTCC12683) with the characterization and functionality in adherence of its surface layer protein (GS4-Slp). The Slp of P. pentosaceus GS4 was extracted purified and detected using SDS-PAGE (98 kDa) and size exclusion chromatography. The cell adherence property of probiotic GS4 (Slp+/Slp-) was evaluated on buccal cells and HCT-116. Purified Slp was found neutralized with raised anti-Slp showing reduced adherence to HCT-116 as evident from SEM analysis. The structure of GS4-Slp was determined by MALDI-TOF analysis, CD analysis, atomic force microscopy (AFM), and FT-IR spectrometry. In Silico approach revealed its indirect similarity with cell membrane protein of Helicobacter pylori. Results thus reveal that GS4 has the potential of the production of 98 kDa Slp which facilitates the cell adherence property. This added probiotic attribute will enhance the probiotic potentials of P. pentosaceus GS4 to use it biotechnologically. SIGNIFICANCE: Probiotic Pediococcus pentosaceus GS4 facilitates demonstrable colonization by the elaboration of Slp. This property imparts a value to the strain and claims to be more useful biotechnologically.

Abstract
Pediococcus pentosaceus GS4 (MTCC 12683), a probiotic lactic acid bacterium (LAB), was found to produce bacteriocin in spent culture. Antibacterial and antagonistic potential of this bacteriocin against reference strains of Staphylococcus aureus (ATCC 25923), Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 25619), and Listeria monocytogenes (ATCC 15313) was proven by double-layer and well diffusion methods wherein nisin and ampicillin were used as positive controls. Bacteriocin in supernatant was purified and analyzed by SDS-PAGE, RP-HPLC, and circular dichroism (CD). The physico-chemical properties of purified bacteriocin were characterized being treated at different temperatures (30 to 110 °C), pH (3.0 to 12.0), with different enzymes (α-amylase, pepsin, and lysozyme), and organic solvents (hexane, ethanol, methanol, and acetone) respectively. The molar mass of bacteriocin (named pediocin GS4) was determined as 9.57 kDa. The single peak appears at the retention time of 2.403 with area amounting to 25.02% with nisin as positive control in RP-HPLC. CD analysis reveals that the compound appears to have the helix ratio of 40.2% with no beta sheet. The antibacterial activity of pediocin GS4 was optimum at 50 °C and at pH 5.0 and 7.0. The pediocin GS4 was not denatured by the treatment of amylase and lysozyme but was not active in the presence of organic solvents. This novel bacteriocin thus m ay be useful in food and health care industry.

Abstract
Conjugated linoleic acid (CLA) has attracted as novel type of fatty acids having unusual health-promoting properties such as anticarcinogenic and antiobesitic effects. The present work employed castor oil as substrate for one-pot production of CLA using washed cells of Lactobacillus plantarum (L. plantarum) and lipases as catalysts. Among the screened lipases, the lipase Rhizopus oryzae (ROL) greatly assisted resting cells to produce CLA. Mass spectral analysis of the product showed that two major isomers of CLA were produced in the reaction mixture i.e. cis-9, trans-11 56.55% and trans-10, cis-12 43.45%. Optimum factors for CLA synthesis were found as substrate concentration (8 mg/mL), pH (6.5), washed cell concentration (12% w/v), and incubation time of 20 h. Hence, the combination of ROL with L. plantarum offers one pot production of CLA selectively using castor oil as a cost-effective substrate.

Abstract
In nutraceutical science, the ingestible live microbes 'probiotics' are regarded for their ability to confer multiplicity of health benefits on the consumers. Wide spectrum impact of these friendly microbes on the host health has been proved very frequently. They have been confirmed to boost immunity, aid in digestion, eliminate pathogens, curb inflammatory bowel diseases, moderate side effects of antibiotic therapy, lower cholesterol and blood glycemic index and produce vitamins. This review, however, focuses on the incipient, but promising area of probiotic diet-based prevention and remedy of cancer. Researchers are in universal agreement with the critical role of probiotics in getting rid of mutagens, delaying the onset of tumors, alleviating the side effects, pepping up chemotherapy, easing the postoperative complications, foiling remission and lifting the spirit of survivors. The key findings in the emerging roles of probiotics in onco-care have been summarized; the biological pathways discussed and anticipated developments in coming times are presented.

Abstract
Probiotic treatment has been gaining attention due to its remarkable effects in alleviating toxicity and carcinogenesis. The novel strain Pediococcus pentosaceus GS4 has been reported for probiotic, survivability in simulated gastrointestinal fluid, and antioxidative and biohydrogenation properties. Therefore, we hypothesize that this specific strain might be able to assuage the effect of azoxymethane (AOM)-induced toxicity in mice. Twenty-eight Swiss albino mice were divided into 4 groups and were studied for 32 weeks. Azoxymethane (10 mg/kg body weight) was administered intraperitoneally twice (0th and 14th days), and probiotic GS4 (1.1 × 10(9) colony-forming unit/mL) was given orally for the respective groups. Mice who served as the normal control received only normal saline. GS4-intervened AOM-induced mice showed marked improvement at the histopathologic level, in the liver and kidney. Moreover, probiotic GS4 intervention in AOM-induced mice exhibited a significant reduction in the liver function biomarker when compared with the AOM-induced mice. Probiotic GS4 intervention reduced the intestinal structural deformities as evident from the elevated brush border membrane-associated disaccharidases (sucrase, lactase) and intestinal alkaline phosphatase activities, which were found disrupted by AOM intoxication. Fecal bacterial load was found to be reduced in AOM-induced mice which were subsequently replenished by the probiotic GS4 intervention as apparent from the enhanced fecal bacterial load. There were no adverse effects observed in the probiotic control group. Conclusively, novel probiotic strain GS4 exhibited safe and beneficial effects against the toxicity threats posed by AOM. Thus, GS4 could be considered as a potential food supplement/additive for therapeutic purposes in gastrointestinal disorders related to inflammation and cancer.

Abstract
The ability of different Lactobacillus strains to produce conjugated linoleic acid (CLA) from linoleic acid was evaluated. Preliminary experiments revealed that L. plantarum among the screened strains had the highest CLA-producing potential (95.25 μg/mL). The cell growth of this bacterium was studied in three media of MRS broth, skim milk and skim milk supplemented with yeast extract and glucose. Results showed that the use of yeast extract and glucose could significantly increase the cell growth and CLA production. Response surface methodology (RSM) was applied to investigate the effects of three independent variables; linoleic acid (LA), yeast extract concentrations and inoculum size on the CLA formation. A second-order polynomial model with high R (2) value (0.981) was developed using multiple linear regression analysis. The optimum conditions to achieve the highest CLA production (240.69 μg/mL) was obtained using 3 mg/mL LA, 4 g/L yeast extract and inoculum size of 4 % v/v. CLA concentration of the optimal sample was analyzed by Gas Chromatography (GC). The cis-9, trans-11 CLA was the major CLA isomer of total CLA detected.
