Abstract
Idesia polycarpa, belonging to the Flacourtiaceae family, is a tall deciduous tree, widely distributed in some Asian countries. It is famous for its high yield of fruit known as oil grape, which is rich of linoleic acid and linolenic acid, and so on. To provide evidences for its safe use as food, subchronic toxicity of I. polycarpa fruit oil and no observed adverse effect level were performed in male and female specific pathogen-free Wistar rats. Based on the Organization for Economic Co-operation and Development guidelines, the oil was orally administered to rats by gavage at 0, 1.0, 2.0, and 4.0mL/kg.bw/day for 90 days, followed by a 28-day recovery period. The results showed that no sign of oil-related toxicity, clinically or histologically, was observed in both male and female rats. Although there was a slight increase or decrease in some indicators such as hematology, serum chemistry, and so on, those changes were all within the normal ranges, and as presented in the 90-day study, the oil exhibited no toxic effect compared to the control rats. I. polycarpa might be a potential excellent and healthy vegetable oil resource.

Extended one generation reproductive toxicity study and effect on gut flora of genetically modified rice rich in β-carotene in wistar rats. Reprod Toxicol 2023; 119:108424. [PMID: 37336333 DOI: 10.1016/j.reprotox.2023.108424] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 06/14/2023] [Accepted: 06/16/2023] [Indexed: 06/21/2023]
Abstract
To evaluate the reproductive toxicity of gene modified rice generated by introducing phytoene synthase (Psy) and bacterial phytoene desaturase (CrtI) from maize and Erwinia uredovora, Wistar rats were allocated into 3 groups and fed with Psy and CrtI gene modified rice mixture diet (GM group), non-gene modified rice mixture diet (non-GM group), and AIN-93 diet (Blank control group) from parental generation (F0) to the offsprings (F1). GM rice, Heijinmi (HJM) and Non-GM rice, Heishuai (HS), were both formulated into diets at ratios of 73.5% and 75.5% according to the AIN93 diet for rodent animals, respectively. Relative to the non-GM group, no biologically relevant differences were observed in GM group rats concerning reproductive performance such as fertility rate, gestation rate, mean duration, hormone level, and reproductive organ pathology. The developmental parameters results were not significantly different from the non-GM group such as body weight, food consumption, developmental neurotoxicity, behavior, hematology, and serum chemistry. In terms of immunotoxicity, the IgG indicators of offspring from the GM group improved in contrast with the non-GM group. Additional gut flora analysis of F0 generation rats resulted as that the treatment elicited an increased gut microflora diversity of F0 rats. And no horizontal gene transfer of Psy and CrtI genes in rats fed a GM rice HJM diet. In conclusion, we found no adverse effects related to GM rice in the extended one-generation reproductive toxicity study, indicating that GM rice is a safe alternative for its counterpart rice regarding reproductive toxicity.

Abstract
Transgenic soybean is one of the most planted crops for human food and animal feed. The channel catfish (Ictalurus punctatus) is an important aquatic organism cultured worldwide. In this study, the effect of six different soybean diets containing: two transgenic soybeans expressing different types of cp4-epsps, Vip3Aa and pat genes (DBN9004 and DBN8002), their non-transgenic parent JACK, and three conventional soybean varieties (Dongsheng3, Dongsheng7, and Dongsheng9) was investigated in juvenile channel catfish for eight weeks, and a safety assessment was performed. During the experiment, no difference in survival rate was observed in six groups. The hepatosomatic index (HSI) and condition factor (CF) showed no significant difference. Moreover, comparable feed conversion (FC), feeding rate (FR), and feed conversion ratio (FCR) were found between transgenic soybean and JACK groups. Assessment of growth performance showed that the weight gain rate (WGR) and specific growth rate (SGR) of channel catfish were consistent. In addition, there were no changes in enzyme activity indexes (lactate dehydrogenase (LDH), total antioxidant capacity (T-AOC), aspartate aminotransferase (AST) and alanine aminotransferase (ALT)) in channel catfish among treatments. The research provided an experimental basis for the aquaculture feed industry to employ transgenic soybean DBN9004 and DBN8002 for commercial purposes.

Abstract
Genetically Modified (GM) foods are among the most important achievements of biotechnology. Given the safety importance of transgenic rice, this study was conducted to investigate the effect of GM rice consumption on serum concentrations of tumor markers in rats. In this experimental intervention, we used the blood serum samples from the Biobank taken from 60 males and 60 female Sprague-Dawley (SD) rats fed on three different diets, including rat's standard food, non-GM rice, and GM rice after 90 day. Tumor markers including Carcinogenic embryonic antigen (CEA), Alpha-Fito protein (AFP), Cancer Antigen 19-9 (CA19-9), Cancer Antigen 125 (CA125), and Cancer Antigen15-3 (CA15-3) were assessed by enzyme-linked immune sorbent assay (ELISA) method. Statistical analysis was conducted via SPSS software. The results show that the concentrations of tumor markers were within the normal range in the SD rats treated with diet, and since the concentration of tumor markers was lower than the acceptable index determined, according to the kit standard in both groups, no obvious carcinogenic effect was found. However, these findings are not enough to make a final decision regarding the safety assessment of GM rice consumption.

Abstract
In the present study, a new genetically modified rice producing phytase-lactoferricin fusion protein, BPL9K-4, was evaluated for safety in a 90-day rat feeding study. Rats were fed rodent diets formulated with BPL9K-4 rice, and were compared with rats fed diets formulated with its corresponding non-transgenic parental rice 9 K, commercially available non-transgenic rice Weiyou64, and a basal diet. BPL9K-4 and 9 K rice were formulated into diets at concentrations of 15%, 30% and 60%, and Weiyou64 common rice was added to diets at concentration of 60%. AIN93G diet was set as a basal-diet control. Diets of all groups were fed to rats (10/sex/group) for 90 days. Compared with rats in the 9 K, Weiyou64 and the basal-diet group, rats fed the BPL9K-4 diet did not show any treatment-related adverse effects on mortality, body weights, feed consumption, clinical chemistry, hematology, organ weights and gross and microscopic pathology. Under the conditions of this study, the genetically modified BPL9K-4 diets did not cause any toxicologically significant effects in rats following 90 days of dietary administration as compared with rats fed diets with the corresponding non-transgenic control diet and the basal-diet group. The results indicated that BPL9K-4 rice is as safe as its conventional comparators.
