CircYthdc2 generates polypeptides through two translation strategies to facilitate virus escape.

It is known that about 10 circular RNAs (circRNAs) can encode functional polypeptides in higher mammals. However, it is not clear whether the functional polypeptides that can be translated by circRNAs are only the products of the evolution of higher animals, or also widely exist in other lower organisms. In addition, it is also unclear whether the two ways of translating polypeptides using IRES and mA in the one circRNA are exclusive or coexistent.

circMORC3-encoded novel protein negatively regulates antiviral immunity through synergizing with host gene MORC3.

The protein-coding ability of circRNAs has recently been a hot topic, but the role of protein-coding circRNAs in antiviral innate immunity of teleost fish has rarely been reported. Here, we identified a novel circRNA, termed circMORC3, derived from Microrchidia 3 (MORC3) gene in Miichthys miiuy. circMORC3 can inhibit the expression of antiviral cytokines.

A novel protein encoded by circVPS13D attenuates antiviral innate immunity by targeting MAVS in teleost fish.

The expression of circVPS13D was upregulated with SCRV invasion, which proved that circVPS13D was involved in the regulation of the antiviral immune response. Our study revealed that the existence of circVPS13D promoted the replication of SCRV. Functionally, circVPS13D negatively regulates the antiviral responses of fish.

Enhancing anti-tumor therapy with agmatine-cholesterol conjugate liposomes: in vitro and in vivo evidence.

In this study, we synthesized a novel compound, agmatine-cholesterol conjugate (AG-Chol), to enhance the anti-tumor activity of drug-loaded liposomes. We replaced cholesterol with AG-Chol in preparing doxorubicin hydrochloride (DOX) liposomes by using an active loading method for DOX. We assessed the physical and chemical properties of the resulting AG-Liposomes and evaluated their efficacy in vitro and in vivo.

CircMIB2 therapy can effectively treat pathogenic infection by encoding a novel protein.

The mRNA therapy is widely used in the treatment of diseases due to its efficient characteristics, and the COVID-19 vaccine is the application of mRNA therapy. However, due to the instability of mRNA, mRNA vaccines often need lots of modifications to ensure its stability. Recent research shows that circRNA with stable RNA structure can encode protein, which provides a new direction for mRNA therapy.

3 and Systems Mediated Base Editing in Kiwifruit Canker Causal Agent pv. .

pv. () causes bacterial canker of kiwifruit with heavy economic losses. However, little is known about the pathogenic genes of .

Circular RNA circRara promote the innate immune responses in miiuy croaker, Miichthys miiuy.

With the in-depth study of circRNA, more and more biological studies have shown that circRNAs play an important role in mammals, such as cell proliferation, apoptosis, invasion, development and disease state. However, the regulatory mechanism of circRNA in lower vertebrates remains unclear. Here, we found a new circular RNA and named it circRara.

The comparative studies of complete chloroplast genomes in Actinidia (Actinidiaceae): novel insights into heterogenous variation, clpP gene annotation and phylogenetic relationships.

The genus Actinidia, also called kiwifruit, is characterized with abundant balanced nutritional metabolites, including exceptionally high vitamin C content. However, the traditional classification could not fully reflect the actual Actinidia species' relationships, which need further revision through more accurate approaches. Compared to the nuclear genome, the chloroplast genome has simple heredity characteristics, conserved genome structure and small size, suitable for deciphering complicated species' phylogenetic relationships.

Magnolol-loaded cholesteryl biguanide conjugate hydrochloride nanoparticles for triple-negative breast cancer therapy.

The potential of combination therapy using nanoparticle delivery systems in improving triple-negative breast cancer treatment efficacy remains to be explored. Here, we report a novel nanoparticle system using a cholesterol biguanide conjugate hydrochloride (CBH) as both a drug and carrier to load magnolol (MAG). Poly(ethylene glycol)-poly(lactic-co-glycolic acid) (mPEG-PLGA) and aminoethyl anisamide-poly(ethylene glycol)-poly(lactic-co-glycolic acid) (AEAA-PEG-PLGA) were added to form nanoparticles.
