Developing Ganoderma lucidum as a next-generation cell factory for food and nutraceuticals.

Ganoderma lucidum holds a colossal reservoir of hydrolytic enzymes and therapeutic compounds and can be a sustainable source of proteins and bioactive compounds. Its metabolic versatility, propelled by its rich genome content, provides excellent biosynthetic machinery for innovation-driven pathway engineering. However, robust regulatory networks and low frequency of homologous recombination are critical bottlenecks that limit the development of molecular tools and precise genetic markers for biomanufacturing innovations in this organism. Modern synthetic biology provides tools that could help to accelerate precise multiple gene targeting and editing and untangling the biosynthetic machinery of G. lucidum. This review provides insight into molecular strategies to unwind the regulatory bottlenecks and transform G. lucidum into efficient cell factories for food and nutraceuticals.

Yiqixue buganshen recipe regulates the expression of integrin ανß3 in the endometrium of controlled ovarian hyperstimulation mice.

OBJECTIVE: To observe the effect of Yiqixue Buganshen recipe(, YBR) on the expression of integrin ανß3 in the endometrium of controlled ovarian hyperstimulation mice. METHODS: A total of 180 mice were divided into three groups: model group, treatment group and control group. The treatment and model groups were intraperitoneally injected with gonadotropin-releasing hormone analogue for 7 days; pregnant mare serum gonadotropin was also injected on the 7th day. After 48 h, human chorionic gonadotropin was injected. The control group was injected with an equal volume of saline at the same time. From the start of the experiment, the treatment group was intragastrically administered Jinghouzengzhi Recipe() and Cuhuangti Recipe(). The model group and the control group were intragastrically administered an equal volume of saline. Real-time reverse transcription polymerase chain reaction and Western blotting were used to detect the mRNA and protein expression of integrin ανß3 in mouse endometrium. RESULTS: Integrin ανß3 was expressed in mouse endometrium in all groups. Integrin αßß3 expression increased gradually along with pregnancy, progressing from pregnant day (Pd) 1. Integrin ανß3 expression significantly increased on Pd 4, then began to decrease on Pd 6. Integrin ανß3 expression in the treatment group was higher than in the model group, and the difference was statistically significant (P <0.05). The difference between the treatment group and the control group was not statistically significant (P >0.05). CONCLUSION: YBR improves endometrial receptivity, and may play an important role in embryonic implantation.
