Potential Role of Curcumin and Its Nanoformulations to Treat Various Types of Cancers

Abstract: Cancer is a major burden of disease globally. Each year, tens of millions of people are diagnosed with cancer worldwide, and more than half of the patients eventually die from it. Significant advances have been noticed in cancer treatment, but the mortality and incidence rates of cancers are still high. Thus, there is a growing research interest in developing more effective and less toxic cancer treatment approaches. Curcumin (CUR), the major active component of turmeric (Curcuma longa L.), has gained great research interest as an antioxidant, anticancer, and anti-inflammatory agent. This natural compound shows its anticancer effect through several pathways including interfering with multiple cellular mechanisms and inhibiting/inducing the generation of multiple cytokines, enzymes, or growth factors including IκB kinase β (IκKβ), tumor necrosis factor-alpha (TNF-α), signal transducer, and activator of transcription 3 (STAT3), cyclooxygenase II (COX-2), protein kinase D1 (PKD1), nuclear factor-kappa B (NF-κB), epidermal growth factor, and mitogen-activated protein kinase (MAPK). Interestingly, the anticancer activity of CUR has been limited primarily due to its poor water solubility, which can lead to low chemical stability, low oral bioavailability, and low cellular uptake. Delivering drugs at a controlled rate, slow delivery, and targeted delivery are other very attractive methods and have been pursued vigorously. Multiple CUR nanoformulations have also been developed so far to ameliorate solubility and bioavailability of CUR and to provide protection to CUR against hydrolysis inactivation. In this review, we have summarized the anticancer activity of CUR against several cancers, for example, gastrointestinal, head and neck, brain, pancreatic, colorectal, breast, and prostate cancers. In addition, we have also focused on the findings obtained from multiple experimental and clinical studies regarding the anticancer effect of CUR in animal models, human subjects, and cancer cell lines.

Moringa rivae leaf extracts attenuate Complete Freund’s adjuvant-induced arthritis in Wistar rats via modulation of inflammatory and oxidative stress biomarkers

Abstract: Moringa rivae is widely used as a traditional remedy against arthritis. The present research was designed to evaluate the anti-arthritic potential of Moringa rivae extracts. Treatment of rats with adjuvant-induced arthritis with methanolic and aqueous extracts of M. rivae (150, 300 or 600 mg/kg), and piroxicam (10 mg/kg) was started orally at day 8 post-administration of complete Freund’s adjuvant and continued till 28th day. The therapeutic effect of the plant extracts was assessed in arthritic rats by arthritic index, body weight, and haematological and biochemical parameters. Furthermore, the modulatory effect on gene expression (I-κB, IL-4 and IL-10, COX-2, IL-1β and IL-6, NF-κB, and TNF-α) in the blood was determined using qRT-PCR, while ELISA assay was used to find PGE2 and TNF-α concentrations in the serum. Oxidative stress parameters in the liver and ankle joint histopathology were also evaluated. Moreover, the most effective methanolic extract was further characterized by GC–MS for the presence of phytochemicals. Treatment with the plant extracts significantly restored arthritic index, change in the body weight and immune organ weight, and the histopathological indices. Both extracts significantly (p < 0.05) reduced the serum concentration of rheumatoid factor, C-reactive protein, PGE2, and TNF-α in arthritic rats. The extracts persuasively down-regulated the COX-2, PGE2, IL-1β, IL-6, NF-κB, and TNF-α, and up-regulated the mRNA expression of I-κB, IL-4, and IL-10. Both extracts increased the activities of CAT and SOD while reducing the formation of MDA in a dose- dependent manner in the liver. Histopathological evaluation showed that treatment with the plant extracts significantly (p < 0.05) reduced joint inflammation, pannus formation, and bone erosion in treatment groups in comparison to arthritic control. Phytochemicals detected by GC–MS in the methanolic extract included esters, alcohols, ketones, fatty acids, and vitamin E. These findings provide evidence of the anti-arthritic potential of M. rivae extracts in chronic polyarthritis model.

Review: Nigella sativa (Prophetic Medicine): A Review.

Abstract: The present report is a significant effort to explore detail description of N. Sativa, its pharmacognostic characteristics, morphological characteristics, and mechanism of actions, doses and medicinal uses. Nigella sativa (N. Sativa) is greatest form of healing medicine. It is also known as Prophetic Medicine as its use has been mentioned in Prophetic Hadit, as natural remedy for all the diseases except death. It is recommended on daily basis in Tibb-e-Nabwi (Prophetic Medicine). Hazrat Abu Hurairah States ''I have heard from Rasool Allah (PBUH) that there is cure for every disease in black seeds except death and black seeds are shooneeze''. Salim Bin Abdullah narrates with reference to his father Hazrat Abdullah Bin Omar that Rasool Allah (PBUH) said, 'Let all the black seed upon you, these contain cure of all diseases except death'. N. sativa claimed to have anti-inflammatory, analgesic, hepato-protective, neuro-protective, gastro-protective and other useful properties. Biological and pharmacological effects are attributed to its two important constituents Thymoquinone (TQ) and Nigella sativa oil (NSO). TQ has interaction with human serum albumin. Seeds containing volatile oils mainly Melanthin showed toxicity at larger doses. This report is a reference for all pharmaceutical researchers, physicians and biologists researching on N. sativa and will open a door towards novel agent.

Genome sequence of mungbean and insights into evolution within Vigna species

Abstract: Mungbean (Vigna radiata) is a fast-growing, warm-season legume crop that is primarily cultivated in developing countries of Asia. Here we construct a draft genome sequence of mungbean to facilitate genome research into the subgenus Ceratotropis, which includes several important dietary legumes in Asia, and to enable a better understanding of the evolution of leguminous species. Based on the de novo assembly of additional wild mungbean species, the divergence of what was eventually domesticated and the sampled wild mungbean species appears to have predated domestication. Moreover, the de novo assembly of a tetraploid Vigna species (V. reflexo-pilosa var. glabra) provides genomic evidence of a recent allopolyploid event. The species tree is constructed using de novo RNA-seq assemblies of 22 accessions of 18 Vigna species and protein sets of Glycine max. The present assembly of V. radiata var. radiata will facilitate genome research and accelerate molecular breeding of the subgenus Ceratotropis.

Effects of yeast (Saccharromyces cerevisiae) cell components on growth performance, meat quality, and ileal mucosa development of broiler chicks.

Abstract: An experiment was conducted with 240, 1-d-old, male broilers to investigate the effects of Saccharomyces cerevisiae (SC) cell components on the growth performance, meat quality, and ileal mucosa development. There were 4 dietary treatments, each consisting of 6 replicates. Whole yeast (WY), SC extract (YE), and SC cell wall (CW) were added at 0.5, 0.3, and 0.3%, respectively, to the control starter and finisher diets. From 0 to 3 wk of age, a lower feed/gain ratio (P < or = 0.05) was observed with CW, whereas the WY-fed birds at 4 to 5 wk of age showed a lower feed/gain ratio compared with the control. From 0 to 5 wk of age, WY and CW gave higher BW gains than did the control. The shear force of raw drumstick decreased in the WY treatment relative to the control, and YE and CW treatments were intermediate. The shear forces in cooked breast and drumstick in treatments WY and YE decreased when compared with the control. The amount of 2-thiobarbituric acid-reactive substances (TBARS) in the breast meats of WY, YE, and CW were lower than the control at 10 d of incubation. In raw drumstick meats, TBARS values were lower in treatments WY and YE than that of the control at 6 and 10 d of incubation. At 10 d of incubation, skins from YE and CW treatments had lower TBARS values than did the control. Villus height was greater in WY and CW compared with those in control and YE. No differences were found in crypt depth among the 4 treatments. The villus height/ crypt depth ratios in WY and CW were greater than those of the control and YE. It could be concluded that dietary yeast components, such as WY or CW supplementation improved growth performance. Meat tenderness could be improved by the WY or YE. Both YE and CW had oxidation-reducing effects. Yeast cell wall may improve ileal villus development.
