Goji berry supplementation in does' diet positively influences both their reproductive and productive performance, likely through adjustment of hormonal patterns and milk production.
In the methodology, this study involved an experiment with 105 nulliparous does divided into three groups two months prior to artificial insemination. The groups were distinguished by their diet: the commercial diet and those supplemented with either 1% or 3% of goji berry. They focused on assessing the effects on hormonal profile and the animals' receptive, productive, and reproductive performance.
The results shed light on increasing receptivity in the group that was supplemented with 1% goji berry over the commercial diet group. Departures noted between both goji-supplemented groups with regard to hormonal concentration, specifically LH, with G1 showing slight edge. There was also a significant interaction effect observed in estrogen concentrations. Additionally, the 1% goji-supplemented group showed higher litter weight than the commercial diet group at both birth and weaning stages, along with a larger litter size at weaning. This group also exhibited the highest average milk production. The study concluded that goji berry supplementation potentially has a positive impact on reproductive and productive performance, possibly through the modulation of hormonal patterns and milk production in rabbits.

Specific fractions of Lycium barbarum, commonly known as Goji berry, reduce heart and kidney damage caused by anthracyclines while possibly enhancing their therapeutic effects.

Animal Study Cardioprotective Cardioprotective Effects Goji Berry
The study investigated the effects of three different fractions of Goji berries (pectin-free, polysaccharides, and a mix of the two) on rat models suffering from doxorubicin-induced damage to the heart and kidneys. The fractions were orally administered at a dose of 2mg/kg while doxorubicin was applied at a total dose of 20mg/kg. Several biomarkers were used to assess heart damage (such as creatine kinase, aspartate aminotransferase, lactate dehydrogenase) and kidney damage (creatinine, blood urea nitrogen, uric acid), along with potassium serum levels. Additionally, a histological analysis of the hearts and kidneys was conducted.
In terms of results, rats treated solely with doxorubicin exhibited a significant increase in all toxicity biomarkers. However, in all groups that also received any of the plant fractions, there was substantial reduction in markers indicating heart and kidney tissue damage. Notably, the pectin-free and combined fractions presented the most substantial decreases in toxicity indicators. These findings were further corroborated by the histological analysis.

Experimental Study Goji Berry Retinitis Pigmentosa
The team carried out both in vivo and in vitro studies. Initially, mouse retinal ganglion cells were categorized into groups based on the doses of Lycium barbarum polysaccharide they were given and a positive drug control group. These cells were then subject to different H2O2 concentrations to induce apoptosis. Techniques such as flow cytometry, immunofluorescence, and western blot were used to evaluate cell viability, apoptosis rate, and expression of various markers. For in vivo research, the team used C57/BL6 and Rd10 mice divided into similar groups as the in vitro experiment. The mice underwent drug treatment for four weeks, after which their retina's response to light and general health were evaluated using an electroretinogram and histopathological examination.
The in vitro experiments showed that the apoptosis rate of ganglion cells significantly increased in the model group, along with up-regulation of certain proteins. However, a high dose of Lycium barbarum polysaccharide decreased the cell apoptosis rate and the levels of certain proteins. Similarly, in vivo testing showed that a high dose of the substance significantly aided in morphological alterations in a retina layer of Rd10 mice, and down-regulated the expression levels of a number of apoptosis-related proteins.

Eighty mice with Retinitis Pigmentosa (RP) were divided into two groups, with one group receiving Zhangyanming Tablets (ZYMT) and a control group getting distilled water. After a period of 7 and 14 days, the researchers conducted tests through electroretinogram, fundus photography, and histological examination to assess the retinal function and structure of the subjects. They furthered the study using TUNEL, immunofluorescence and qPCR to evaluate cell apoptosis and the expressions of particular genes.
The ZYMT-treated mice displayed a notable enhancement in retinal reactions and overall preservation of retinal structure when compared to the control group. Particularly noticeable were increases in retinal thickness and cell count, alongside a significantly lowered rate of cell death. A comprehensive follow-up shows the altered expressions of several genes in the retina following the application of ZYMT. These results, combined, suggest a key role of ZYMT in mitigating the effects of RP especially in early stages.

The research used various databases such as Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, GeneCards, and the Online Mendelian Inheritance in Man database to gather the ingredients of RALRG and potential targets of RP and RALRG. A protein-protein interaction network was constructed to visualize these interactions. The R program was utilized to perform functional enrichment. The researchers constructed a visual RALRG-RP-pathway pharmacology network using Cytoscape 3.9.1 and applied molecular docking to compute binding affinity.
The research revealed a total of 132 effective active elements in RALRG correlating to 248 target genes. Ninety-two intersection target genes were discovered from the overlap of RP- and RALRG-related genes. These intersection targets were discovered to be primarily involved in oxidative stress, responding to metal ions, and handling chemical stress. Several molecular pathways such as PI3K-AKT and MAPK were identified as closely connected to RP therapy. A potential pharmacology network was designed for the RALRG-RP-pathway with AKT1 and JUN being considered the main targets. The active ingredients luteolin, quercetin, and kaempferol were highlighted as crucial for this mechanism. RALRG overall was established as a main regulator for oxidative stress and PI3K/AKT signaling pathways in the treatment of RP.
Berries, largely due to their phenolic compounds, enhance internal antioxidant status and positively influence gut microbiota composition, promoting beneficial bacteria and suppressing harmful types.

Experimental Study Antioxidant Blackberry Goji Berry
The study compared the antioxidant capacities and gut microbiota modulatory effects of nine popular berries: blackberry, black goji berry, blueberry, mulberry, red Chinese bayberry, raspberry, red goji berry, strawberry, and white Chinese bayberry. The anthocyanin profiles of each berry were identified using Ultra-performance liquid chromatography (UPLC) coupled with Triple TOF/MS. The antioxidant capacities were evaluated through four chemical assays (DPPH, ABTS, FRAP, and ORAC). Healthy mice were treated with different berry extracts for two weeks as a means of investigating in vivo antioxidant capacity and gut microbiota modulatory effects.
In terms of the results, it was observed that majority of the berries improved the internal antioxidant status, indicated by elevated serum or colonic Total Antioxidant Capacity (T-AOC), Glutathione (GSH), Total Superoxide Dismutase (T-SOD), Catalase (CAT), and Glutathione Peroxidase (GSH-PX) levels, along with a decrease in Malondialdehyde (MDA) content. All berries studied notably altered the gut microbiota composition, with most leading to the enrichment of beneficial Short Chain Fatty Acids (SCFAs)-producing bacteria and the curbing of potentially harmful bacterial types.
