Royal jelly protects brain tissue against fluoride-induced damage by activating Bcl-2/NF-κB/caspase-3/caspase-6/Bax and Erk signaling pathways in rats.

This study is aimed at determining whether royal jelly (RJ) which has a powerful antioxidant property prevents fluoride-induced brain tissue damage and exploring whether Bcl-2/NF-κB/ and caspase-3/caspase-6/Bax/Erk pathways play a critical role in the neuroprotective effect of RJ. Wistar albino rats were chosen for the study, and they were randomly distributed into six groups: (i) control; (ii) royal jelly; (iii) fluoride-50; (iv) fluoride-100; (v) fluoride-50 + royal jelly; (vi) fluoride-100 + royal jelly. We established fluoride-induced brain tissue damage with 8-week-old male Wistar albino rats by administration of fluoride exposure (either 50 mg/kg or 100 mg/kg bw) through drinking water for 8 weeks.

Royal jelly arranges apoptotic and oxidative stress pathways and reduces damage to liver tissues of rats by down-regulation of Bcl-2, GSK3 and NF-κB and up-regulation of caspase and Nrf-2 protein signalling pathways.

A new approach on the regulation of NF-κB and Bax protein signaling pathway activation by royal jelly in fluoride-induced pancreas damage in rats.

Forty-two healthy adult male rats (Wistar albino, n = 42, 8 weeks old, starting weights 200-250 g) employed in this study were subdivided into six groups randomly with seven rats per group as follows: (i) Control group: received standard diet; (ii) RJ group: received standard diet supplemented with royal jelly; (iii) F50 group: received standard diet supplemented with fluoride (50 mg/kg BW); (iv) F100 group: received standard diet supplemented with fluoride (100 mg/kg BW); (v) F50 +RJ group: received standard diet supplemented with fluoride (50 mg/kg BW) and royal jelly; (iv) F100 +RJ group: received standard diet supplemented with fluoride (100 mg/kg BW) and royal jelly. The study continued for a total of eight weeks. Western blot analysis was conducted to determine the post-translational expression levels of NF-κB, Bax, Bcl-2, TNF-α, Caspase-3 and Caspase-6 proteins in pancreas tissue.

Protective effect of royal jelly on fluoride-induced nephrotoxicity in rats via the some protein biomarkers signalling pathways: a new approach for kidney damage.

Introduction: Protective effect of royal jelly (RJ) on fluoride-induced nephrotoxicity was investigated in this study.

Methods: 42 healthy male Wistar rats (n = 42, 8 weeks of age) were divided equally into 6 groups with 7 rats in each; (1) Group-1: Controls fed with standard diet; (2) Group-2: RJ [100 mg/kg] bw (body weight), by oral gavage; (3) Group-3: Fluoride [50 mg/kg] bw, in drinking water; (4) Group-4: Fluoride [100 mg/kg] bw, in drinking water; (5) Group-5: RJ [100 mg/kg] bw, by oral gavage + Fluoride [50 mg/kg] bw, in drinking water; (6) Group-6: RJ [100 mg/kg] bw, by oral gavage + Fluoride [100 mg/kg] bw, in drinking water. After 8 weeks, all rats were decapitated and their kidney tissues were removed for further analysis.

Royal jelly regulates the caspase, Bax and COX-2, TNF-α protein pathways in the fluoride exposed lung damage in rats.

The study was carried out on 42 male rats divided into six groups with 7 rats in each group: two control groups, two injury groups and two treatment groups. One of the control groups received a basal diet while the other one was fed a basal diet supplemented with royal jelly (RJ) (100 mg/kg). The two injury groups were given 50 mg/kg and 100 mg/kg fluoride, respectively.

The inducing of caspase and Bcl-2 pathway with royal jelly decreases the muscle tissue damage exposed with fluoride in rats.

In this study, 42 Wistar albino male rats (n = 42, 8 weeks old) were used. Rats were divided into 6 groups and 7 rats included each group. Groups: (i) Control group: Standard diet; (ii) RJ (royal jelly) group: Standard diet + royal jelly; (iii) F50 group: Standard diet + 50 mg/kg fluoride; (iv): F100 group: Standard diet + 100 mg/kg fluoride; (v) F50+RJ group: Standard diet + 50 mg/kg fluoride + royal jelly; (vi): F100+RJ group: Standard diet + 100 mg/kg fluoride + royal jelly.

Royal jelly abrogates flouride-induced oxidative damage in rat heart tissue by activating of the nrf-2/NF-κB and bcl-2/bax pathway.

Royal jelly is known to strengthen memory, provide antioxidative, antidiabetic, antitumor, anticancer, antibacterial, antiinflammatory, antihypertensive. In this study, 42 rats (n = 42) were used, and these rats were divided into 6 groups of 7 rats each. Groups: (i) Control Group: Group fed with standard diet; (ii) Royal Jelly (RJ) Group: RJ (100 mg/kg bw, gavage); (iii) F50 Group: Fluoride (50 mg/kg bw, drinking water); (iv) F100 Group: F (100 mg/kg bw, drinking water); (v) F50 + RJ Group: F (50 mg/kg bw, drinking water) + RJ (100 mg/kg bw, gavage); (vi) F100 + RJ Group: F (100 mg/kg bw, drinking water) + RJ (100 mg/kg bw, gavage).

The impact of ellagic acid on some apoptotic gene expressions: a new perspective for the regulation of pancreatic Nrf-2/NF-κB and Akt/VEGF signaling in CCl-induced pancreas damage in rats.

Objective: The aim of this study was to evaluate the potential effect of ellagic acid (EA) in the treatment of pancreatic injury. EA has been found to have strong anti-inflammatory, antioxidative, and anticancer properties. The effects of EA on pancreati˜c star cell (PSC) activation and cell functions have been evaluated and it has been shown that it inhibits the activation of basic cell functions and PSCs and it has antidiabetic activity through its effect on β-pancreas cells.

Material And Methods: Four groups were used in this study. i: Control group, ii: H2O2 group, iii: Pomegranate juice (PJ) group and iv: PJ + H2O2 group.

Milk thistle impedes the development of carbontetrachloride-induced liver damage in rats through suppression of bcl-2 and regulating caspase pathway.

Aim: The objective of this study was to examine whether MT plays a protective role against the damage in the liver by administering carbontetrachloride (CCl4) to rats.

Main Method: 28 male Wistar albino (n=28, 8weeks old) rats have been used in the study. The rats were distributed into 4 groups according to their live weights.
