Evaluation of the therapeutic effect of crocin along with standard regimes in colorectal cancer

ABSTRACT: Intervention 1: Intervention group: Crocin along with standard regime will be assigned to intervention group. The daily dose of crocin will be 30 mg (two 15 mg tablets) during 12 weeks. Intervention 2: Control group: The treatment regimen is with Folfiri, Folfox or Xelox and also placebo without Targeted therapy. Primary outcome(s): Overall survival. Timepoint: One year after the treatment is completed. Method of measurement: Patient follow-up. Study Design: Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Random allocation rule.This study with a sample size of 100 people, 50 balls for the placebo group and 50 balls for the intervention group are placed in a container and then the balls are randomly selected without replacement, Blinding description: Sequentially numbered, sealed, opaque envelopes. A random sequence is created by random allocation rule. Then, based on the sample size, 100 envelopes with aluminum foil inside (to prevent ‘’hot lighting’’) are prepared. Each entity in the random sequence is noted on a card and are replaced in numbered envelop. Finally, the envelopes are sealed and placed in boxes, respectively. The envelops are respectively assigned to each participant so the participant’s assigned group is revealed.

Project description:Folate, and its synthetic form folic acid, function as donor of one-carbon units and have been, together with other B-vitamins, implicated in programming of epigenetic processes such as DNA methylation during early development. To what extent regulation of DNA methylation can be altered via B-vitamins later in life, and how this relates to health and disease, is not exactly known. The aim of this study was to identify effects of long-term supplementation with folic acid and vitamin B12 on genome-wide DNA methylation in elderly subjects. This project was part of a randomized, placebo-controlled trial on effects of supplemental intake of folic acid and vitamin B12 on bone fracture incidence (B-PROOF study). Participants with mildly elevated homocysteine levels, aged 65-75 years, were randomly assigned to take 400 µg folic acid and 500 µg vitamin B12 per day or a placebo during an intervention period of two years. DNA was isolated from buffy coats, collected before and after intervention, and genome-wide DNA methylation was determined in 87 participants (n=44 folic acid/vitamin B12, n=43 placebo) using the Infinium HumanMethylation450 BeadChip. After intervention with folic acid and vitamin B12, 162 (versus 14 in the placebo group) of the 431,312 positions were differentially methylated as compared to baseline. Comparisons of the DNA methylation changes in the participants receiving folic acid and vitamin B12 versus placebo, revealed one single differentially methylated position (cg19380919) with a borderline statistical significance. However, based on the analyses of differentially methylated regions (DMRs) consisting of multiple positions, we identified 6 regions that differed statistically significantly between the intervention and placebo group. Pronounced changes were found for regions in the DIRAS3, ARMC8 and NODAL genes, implicated in carcinogenesis and early embryonic development. Furthermore, serum levels of folate and vitamin B12 or plasma homocysteine were related to DNA methylation of 173, 425 and 11 regions, respectively. Interestingly, for several members of the developmental HOX genes, DNA methylation was related to serum levels of folate. Long-term supplementation with folic acid and vitamin B12 in elderly subjects resulted in effects on DNA methylation of several genes, among which genes implicated in developmental processes.

Project description:Intervention 1: Intervention group: Subjects in the intervention group receive curcumin-piperine capsules (daily intake of 500 mg curcumin plus 5 mg piperine) for 8 weeks (n=36). The participants take one capsule every day, which was contained in an unlabeled bottle. Capsules are from Sami Labs company (Bangalore, India). Intervention 2: Control group: Placebo capsules are prepared by a similar company and are similar to the curcumin capsules regarding the color, shape and size. The control group receive a placebo capsule containing lactose plus 5 mg piperine for a period of 8 weeks (n=36). The participants take one capsule every day, which was contained in an unlabeled bottle. Capsules are from Sami Labs company (Bangalore, India). Primary outcome(s): Tumor necrosis factor alpha. Timepoint: Before the intervention and 8 weeks after taking drug or placebo. Method of measurement: Sandwich and competitive chemiluminescence immunoassays.;Interleukin 6. Timepoint: Before the intervention and 8 weeks after taking drug or placebo. Method of measurement: Sandwich and competitive chemiluminescence immunoassays.;Total quality of life score. Timepoint: Before the intervention and 8 weeks after taking drug or placebo. Method of measurement: Using EORTC QLQ questionnaire. Study Design: Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Patients were randomly assigned to one of the treatment groups based on random allocation sequence generated by a statistician: 1) Drug: a group receiving liposomal curcumin capsules (500 mg/day) for 8 weeks (n=36), 2) Placebo: the control group who taking a placebo capsule for a period of 8 weeks (n=36).The tables of the Fleiss book were used to generate the random allocation sequence. The allocation scheme was consecutively numbered in envelopes which opened sequentially by an independent person, not involved in the study, Blinding description: All volunteers, care providers and statistician were blinded after assignment to intervention. So that, the capsules containers were coded as A and B by a non-researcher person and remained confidential until statistical analysis. The placebo capsules were similar to the drugs regarding the weight and c
