Aim: To construct Tat-HBV targeted ribonuclease fusion protein prokaryotic expression vector and express it in E.coli.
Methods: The cDNAs encoding HBV targeted ribonuclease, human eosinophil-derived neurotoxin and HBV core protein were respectively cloned into prokaryotic expression vector pTAT-HA. Recombinant plasmids were transformed into E.coli BL21(DE3) LysS, then the transformed cells were induced with IPTG. The expression of the fusion proteins were analyzed by SDS-PAGE and Western blot.
Results: The three recombinant plasmids were constructed and expressed after IPTG induction successfully.
Conclusion: The obtained Tat-HBV targeted ribonuclease fusion protein has laid the foundation for using TR in therapy of HBV infection.

Background: Argonaute2 (Ago2) plays an essential role in RISC-mediated silencing of target mRNAs, which are critical for cellular functions. Argonaute2 Syndrome, also known as Ago2 Syndrome, is a rare neurological disorder recently discovered in humans. It has significant implications for brain development, yet it remains unstudied to date METHOD: To study this effect, we deleted the Ago2 gene in GABAergic (Slc32a1 cre) and Glutamatergic (Slc17a6 cre) mice.

Hypomethylating agents (HMAs) such as azacytidine and decitabine are FDA-approved chemotherapy drugs for hematologic malignancy. By inhibiting DNA methyltransferases, HMAs reactivate tumor suppressor genes (TSGs) and endogenous double-stranded RNAs (dsRNAs) that limit tumor growth and trigger apoptosis via viral mimicry. Yet, HMAs show limited effects in many solid tumors despite the strong induction of TSGs and dsRNAs.

Mesenchymal Stromal/Stem Cells (MSCs) are among the most frequently studied cell types in clinical trials, and their small extracellular vesicles (sEVs) are now being extensively investigated for therapeutic applications. The RNA cargo of MSC-sEVs, particularly miRNAs and mRNAs, is widely believed to be a key therapeutic component of these vesicles. In this review, we critically examine using first principles and peer-reviewed literature, whether MSC- extracellular vesicles (MSC-EVs) can deliver sufficient quantity of functional miRNA or mRNA to target compartments within recipient cells to elicit a pharmacological response.

tRNA-derived stress-induced RNAs (tiRNAs) are a new class of small non-coding RNA that have emerged as important regulators of cellular stress responses. tiRNAs are derived from specific tRNA cleavage by the stress-induced ribonuclease angiogenin (ANG). Loss-of-function mutations in the ANG gene are linked to amyotrophic lateral sclerosis (ALS), and elevated levels of specific tiRNAs were recently identified in ALS patient serum samples.

Fungal pathogens produce secretory ribonuclease (RNase) T2 proteins during infection, which contribute to fungal virulence via their enzyme functions in degradation of host cell RNA. However, the details of those proteins entering the host cells are unclear. Our previous study demonstrated that the two secretory RNase T2 members, BbRNT2 and BbTrv, produced by the insect fungal pathogen Beauveria bassiana, caused cytotoxic damage to insect cells and contributed to fungal virulence.
