There is a growing interest in butyrate because its impact on epigenetic mechanisms will lead to more specific and efficacious therapeutic strategies for the presentation and treatment of different disease ranging from genetic/metabolic conditions to neurological degeneration disorders. The dietary natural source of butyrate through a high fiber diet or butyrate produced by fermentation of non-digestive fiber, such as acemannan in Aloe Vera leaf gel, is a highly appealing approach to present a simple and relatively low risk method to potentially improve outcomes in aged people with brain troubles. In this review, we will discuss the pharmacological effects of butyrate as a histone deacetylase inhibitor to an insulin resistance and energy expenditure, and as pro-drugs to ulcerative colitis and cancer, and the gut-liver axis in pre-clinical treatment.

The co-administration of absorption enhancing agents with macromolecular drugs (e.g., protein and peptide drugs) has been identified as a means to improve the oral bioavailability of these drugs. Absorption-enhancing agents of natural origins have received a great deal of attention due to their sustainable production, in support of green chemistry. In previous studies, certain parts of the Aloe vera leaf (e.g., gel and whole leaf extract) have shown a potential to enhance drug permeation across the intestinal epithelial barrier. The mechanism of the drug-absorption-enhancement action and the capacity for absorption-enhancement of the A. vera gel and whole leaf, were investigated in this study. A clear decrease in transepithelial electrical resistance (TEER) of Caco-2 cell monolayers exposed to A. vera gel and wholeleaf extract, in various concentrations, indicated the opening of tight junctions between the epithelial cells. The transport of Fluorescein isothiocyanate (FITC)-dextran, with a molecular weight of 4 kDa (FD-4), could be enhanced across the Caco-2 cell monolayers, by the A. vera gel and whole-leaf extract, but not the FITC-dextran with larger molecular weights (i.e., 10, 20, and 40 kDa), which indicated a limited drug absorption enhancement capacity, in terms of the molecular size. Accumulation of FD-4 between the Caco-2 cells (and not within the cells), after treatment with the A. vera gel and whole-leaf extract was shown with a confocal laser scanning microscopy (CLSM) imaging, indicating that the paracellular transport of FD-4 occurred after the interaction of the A. vera gel and whole-leaf extract, with the epithelial cell monolayers. Furthermore, changes in the F-actin distribution in the cytoskeleton of the Caco-2 cell monolayers was observed by means of a fluorescence staining, which confirmed tight junction modulation as the mechanism of action for the absorption enhancement effect of the A. vera gel and whole-leaf extract.

Objective: In the living organisms, deleterious effects produced by ionizing radiations. Human exposure to ionizing radiations increased enormously because of rapid technological advancements. There is a need to protect humans against such effects of ionizing radiation. Protection against the deleterious effects of ionizing radiations by radioprotectors was studied, which may be of great help for human application. Present study was conducted to evaluate the modulating efficacy of prolonged administration of Aloe vera extract against gamma irradiation-induced toxicity in mice. Methods: Animals were given Aloe vera leaf extract orally 1000 mg/kg body weight/d for 15 consecutive days before radiation exposure (0.5, 3 and 5.5 Gy gamma radiation). Results: Mice were autopsied at day ¼, 1, 3, 5, 10 and 20 after irradiation to evaluate the radio modulator effect in terms of the hepatosomatic index. Conclusion: Aloe vera extract has a beneficial protective effect against radiation-induced oxidative stress.

The processed Aloe vera gel (PAG) contains immunomodulatory polysaccharides, which consists of a mixture of polymer chains of b-(1,4)-linked acetylated galactomannan with different lengths. PAG was shown to inhibit azoxymethane(AOM)-initiated and dextran sodium sulfate(DSS)-promoted colon carcinogenesis model in mice. In the present study, we examined the molecular mechanisms for the inhibition of colitis-associated colon carcinogenesis by PAG. PAG administration significantly inhibited the production of pro-inflammatory cytokines and mediators in the colon. Western blot analysis using the colon extracts showed that PAG administration reduced the activation of NF-kB resulting in the inhibition of iNOS and COX-2 expression. PAG appeared to inhibit NF-kB activation through the PPARγ activation. PAG administration also inhibited the expression and phosphorylation of STAT3, which was known to connect inflammation and cancer. PAG administration also inhibited cell cycle progression-related transcription factors such as the proliferating cell nuclear antigen (PCNA), ERK, cyclin-dependent kinase (CDK) 4 and cyclin D1. In contrast, PAG administration increased the expression of CDX2, which was known to be a tumor suppressor in colorectal cancers. These findings show that PAG suppresses colitis-related colon carcinogenesis by inhibiting both chronic inflammation and cell cycle progression in the colon.

The efficacy of Aloe vera has been known for various health and disease-related conditions. Butyrate, a well-known epigenetic histone deacetylase inhibitor, is causally implicated in tumorigenesis and tumor angiogenesis. Butyrate was shown to induce cell cycle arrest, differentiation, and apoptosis in a variety of cancer cells. Dietary factors, microbiota composition, and microbiota metabolism are intimately intertwined in a complex network, highlighting the importance of intestinal functions for health maintenance. In the present review, we discuss aloe vera fermentation as a tumor-suppressive process generating microbial-derived butyrate.

Background Dermatophytosis in calves is a major public and veterinary health concern worldwide because of its zoonotic potential and associated economic losses in cattle farms. However, this condition has lacked adequate attention; thus, to develop effective control measures, we determined ringworm prevalence, risk factors, and the direct-sample nested PCR diagnostic indices compared with the conventional methods of dermatophytes identification. Moreover, the phenolic composition of an Aloe vera gel extract (AGE) and its in vitro and in vivo antidermatophytic activity were evaluated and compared with those of antifungal drugs. Results Of the 760 calves examined, 55.79% (424/760) showed ringworm lesions; 84.91% (360/424) were positive for fungal elements in direct-microscopy, and 79.72% (338/424) were positive in culture. Trichophyton verrucosum was the most frequently identified dermatophyte (90.24%). The risk of dermatophytosis was higher in 4–6-month-old vs. 1-month-old calves (60% vs. 41%), and in summer and winter compared with spring and autumn seasons (66 and 54% vs. 48%). Poor hygienic conditions, intensive breeding systems, animal raising for meat production, parasitic infestation, crossbreeding, and newly purchased animals were statistically significant risk factors for dermatophytosis. One-step PCR targeting the conserved regions of the 18S and 28S genes achieved unequivocal identification of T. verrucosum and T. mentagrophytes in hair samples. Nested-PCR exhibited an excellent performance in all tested diagnostic indices and increased the species-specific detection of dermatophytes by 20% compared with culture. Terbinafine and miconazole were the most active antifungal agents for dermatophytes. Gallic acid, caffeic acid, chlorogenic acid, cinnamic acid, aloe-Emodin, quercetin, and rutin were the major phenolic compounds of AGE, as assessed using high-performance liquid chromatography (HPLC). These compounds increased and synergized the antidermatophytic activity of AGE. The treated groups showed significantly lower clinical scores vs. the control group (P

The medicinal and other claimed uses of Aloe vera, the “wonder plant”, are endless. The extract for phytochemical analysis was collected in three different solvents, diethyl ether, ethanol and distilled water. The anti-fungal activities of the leaf extract were investigated on selected fungi organisms; Trycophytum rubrum, Penicillum notatum, Trycophytum vericophytum, Trycophytum soundanense, Claudosporium and Trycophytum mentagrophytis collected from Mycology Laboratory, University of Nigeria Teaching Hospital, Enugu, Nigeria. The plant extract was collected crude without solvent and agar-well diffusion method employed for the determination of antifungal activities on the test organisms using 200 mg ketoconazole drug as standard. The phytochemical constituents of aloe vera leaf include alkaloids, flavonoids, saponin, phenol, glycosides and tannins. Both undiluted and half diluted crude extract showed different zones of inhibition on the test organisms. The undiluted crude extract of Aloe vera had larger zone of inhibition on Trycophytum rubrum and Trycophytum mentagrophytis than the diluted crude extract while the diluted crude extract showed larger zone of inhibition on Trycophytum vericopytum than the undiluted crude extract.Keywords: Aloe vera, Phytochemicals, Constituents, Antifungal properties
