A comprehensive analysis of the Bencao (herbal) small RNA Atlas reveals novel RNA therapeutics for treating human diseases.

Cross-kingdom herbal miRNA was first reported in 2012. Using a modified herbal extraction protocol, we obtained 73,677,287 sequences by RNA-seq from 245 traditional Chinese Medicine (TCM), of which 20,758,257 were unique sequences. We constructed a Bencao (herbal) small RNA (sRNA) Atlas ( http://bencao.bmicc.cn ), annotated the sequences by sequence-based clustering, and created a nomenclature system for Bencao sRNAs. The profiles of 21,757 miRNAs in the Atlas were highly consistent with those of plant miRNAs in miRBase. Using software tools, our results demonstrated that all human genes might be regulated by sRNAs from the Bencao sRNA Atlas, part of the predicted human target genes were experimentally validated, suggesting that Bencao sRNAs might be one of the main bioactive components of herbal medicines. We established roadmaps for oligonucleotide drugs development and optimization of TCM prescriptions. Moreover, the decoctosome, a lipo-nano particle consisting of 0.5%-2.5% of the decoction, demonstrated potent medical effects. We propose a Bencao (herbal) Index, including small-molecule compounds (SM), protein peptides (P), nucleic acid (N), non-nucleic and non-proteinogenic large-molecule compounds (LM) and elements from Mendeleev's periodic table (E), to quantitatively measure the medical effects of botanic medicine. The Bencao sRNA Atlas is a resource for developing gene-targeting oligonucleotide drugs and optimizing botanical medicine, and may provide potential remedies for the theory and practice of one medicine.

Oral administration of the herbal oligonucleotide XKC-sRNA-h3 prevents angiotensin II-induced hypertension in mice.

Hypertension has become a growing public health concern worldwide. In fact, hypertension is commonly associated with increased morbidity and mortality. Currently, oligonucleotide drugs have proven to be promising therapeutic agents for various diseases. In the present study, we aimed to demonstrate that a herbal small RNA (sRNA), XKC-sRNA-h3 (B55710460, F221. I000082.B11), exhibits potent antihypertensive effects by targeting angiotensin-converting enzyme (ACE) in mice. When compared with captopril, oral administration of the sphingosine (d18:1)-XKC-sRNA-h3 bencaosome more effectively prevented angiotensin II-induced hypertensive cardiac damage and alleviated kidney injury in mice. Such findings indicated that XKC-sRNA-h3 may be a novel orally available ACE inhibitor type oligonucleotide drug for hypertension.

Herbal small RNAs in patients with COVID-19 linked to reduced DEG expression.

In China, more than 80% of patients with coronavirus disease 2019 (COVID-19) received traditional Chinese medicine (TCM) as a treatment and their clinical efficacy have been reported. However, the underlying molecular mechanism remains unclear. Previous studies have identified herbal small RNAs (sRNAs) as novel functional components. In this study, a cohort of 22 patients with COVID-19 treated with Toujie Quwen (TQ) granules was analyzed. We observed thousands of herbal small RNAs that entered the blood cells of patients after the consumption of TQ granules. In response to this treatment, the reduced differentially expressed genes (DEGs) were highly correlated with the predicted target genes of the most prevalent herbal sRNAs detected in the blood. Moreover, the predicted target genes of the top 30 sRNAs from each of the 245 TCMs in the Bencao sRNA Atlas overlapped with 337 upregulated DEGs in patients with mild COVID-19, and 33 TCMs, with more than 50% overlapping genes were identified as effective TCMs. These predicted target genes of top 30 sRNAs from Juhong, Gualoupi and Foshou were confirmed experimentally. Our results not only elucidated a novel molecular mechanism of TCM potential clinical efficacy for COVID-19 patients, but also provided 33 effective COVID-19 TCMs for prescription optimization.

18:0 Lyso PC, a natural product with potential PPAR-γ agonistic activity, plays hypoglycemic effect with lower liver toxicity and cardiotoxicity in db/db mice.

Rosiglitazone, a specific agonist of peroxisome proliferator-activated receptor-γ (PPAR-γ), displays a robust hypoglycemic action in patients with type 2 diabetes mellitus (T2DM) and elicits serious adverse reactions, especially hepatotoxicity and cardiotoxicity. Here, we aims to find a new natural PPAR-γ agonist with less adverse reactions than rosiglitazone in db/db mice. The method of virtual screening was used to identify a PPAR-γ agonist 18:0 Lyso PC from an in-house natural product library. We verified its pharmacological effects and adverse reactions comparing with rosiglitazone in vivo and in vitro. 18:0 Lyso PC exhibited pharmacological effects similar to those of rosiglitazone in db/db mice. Moreover, 18:0 Lyso PC showed a lower extent of liver injury and cardiotoxicity in db/db mice. The mechanism, by which this natural compound alleviates metabolic syndrome, involves a reduction in fatty acid synthesis mediated by activation of the phosphorylation of adenosine 5'-monophosphate (AMP)-activated protein kinase-alpha (AMPKα) and acetyl-CoA carboxylase (ACC) and an increase expression of uncoupled protein 1 (UCP1) and PPAR-γ coactivator-1 alpha (PGC1-α). 18:0 Lyso PC, a natural compound, can show a similar hypoglycemic effect to rosiglitazone by activating PPAR-γ, while eliciting markedly fewer adverse reactions than rosiglitazone.

A botanical medicine dragon's blood exhibited clinical antithrombosis efficacy similar to low molecular weight heparin.

Deep vein thrombosis (DVT) is a common complication following traumatic fracture with a 0.5%-1% annual incidence. Low molecular weight heparin (LMWH) is the most commonly used anticoagulation drug for DVT prevention, but treatment with LMWH is invasive. Our aim is to compare the antithrombotic effect of dragon's blood, an oral botanical anticoagulant medicine approved by the Chinese FDA, with LMWH in patients undergoing hip fracture surgery and to explore the molecular mechanisms of anticoagulation treatment. Our study recruited patients and divided them into LMWH and dragon's blood treatment group. Coagulation index tests, Doppler ultrasound and mRNA sequencing were performed before and after anticoagulation therapy. There was no significant difference in postoperative DVT incidence between the two groups (23.1% versus 15.4%, P=0.694). D-dimer (D-D) and fibrinogen degradation product (FDP) showed significant reductions in both groups after anticoagulation treatments. We identified SLC4A1, PROS1, PRKAR2B and seven other genes as being differentially expressed during anticoagulation therapy in both groups. Genes correlated with coagulation indexes were also identified. Dragon's blood and LMWH showed similar effects on DVT and produced similar gene expression changes in patients undergoing hip fracture surgery, indicating that dragon's blood is a more convenient antithrombosis medicine (oral) than LMWH (hypodermic injection).

Erratum to: Herbal decoctosome is a novel form of medicine.

Following the published article, we noticed an error duplication in Figure 5G "control" and "PGY-6" that was introduced during the revised process, with an attempt to replace it with higher-resolution images. Here we provide the original data in the first submitted manuscript (Figure 5G).

Herbal decoctosome is a novel form of medicine.

Traditionally, herbal medicine is consumed by drinking decoctions produced by boiling herbs with water. The functional components of the decoction are heat stable. Small RNAs (sRNAs) were reported as a new class of functional components in decoctions. However, the mechanisms by which sRNAs survive heat treatment of the decoction and enter cells are unclear. Previous studies showed that plant-derived exosome-like nanoparticles (ELNs), which we call botanosomes, could deliver therapeutic reagents in vivo. Here, we report that heat-stable decoctosomes (ELNs) from decoctions have more therapeutic effects than the decoctions in vitro and demonstrate therapeutic efficacy in vivo. Furthermore, sRNAs, such as HJT-sRNA-m7 and PGY-sRNA-6, in the decoctosome exhibit potent anti-fibrosis and anti-inflammatory effects, respectively. Decoctosome is comprised of lipids, chemical compounds, proteins, and sRNAs. A medical decoctosome mimic is called bencaosome. A single lipid sphinganine (d22:0) identified in the decoctosome was mixed and heated with the synthesized sRNAs to form the simplest bencaosome. This simple bencaosome structure was identified by critical micelle concentration (cmc) assay that sRNAs coassembled with sphinganine (d22:0) to form the lipid layers of vesicles. The heating process facilitates co-assembly of sRNAs and sphinganine (d22:0) until a steady state is reached. The artificially produced sphinganine-HJT-sRNA-m7 and sphinganine- PGY-sRNA-6 bencaosomes could ameliorate bleomycin-induced lung fibrosis and poly(I:C)-induced lung inflammation, respectively, following oral administration in mice. Our study not only demonstrates that the herbal decoctosome may represent a combinatory remedy in precision medicine but also provides an effective oral delivery route for nucleic acid therapy.

Large-scale analysis of small RNAs derived from traditional Chinese herbs in human tissues.

Plant-derived microRNAs have recently been reported to function in human blood and tissues. Controversy was immediately raised due to possible contamination and the lack of large sample sizes. Here, we report thousands of unique small RNAs derived from traditional Chinese medicine (TCM) herbs found in human blood cells and mouse lung tissues using a large-scale analysis. We extracted small RNAs from decoctions of 10 TCM plants (Ban Zhi Lian, Chai Hu, Chuan Xin Lian, Di Ding Zi Jin, Huang Qin, Jin Yin Hua, Lian Qiao, Pu Gong Ying, Xia Ku Cao, and Yu Xing Cao) and obtained millions of RNA sequences from each herb. We also obtained RNA-Seq data from the blood cells of humans who consumed herbal decoctions and from the lung tissues of mice administered RNAs from herbal decoctions via oral gavage. We identified thousands of unique small RNA sequences in human blood cells and mouse lung tissues. Some of these identified small RNAs from Chuan Xin Lian and Hong Jing Tian could be mapped to the genomes of the herbs, confirming their TCM plant origin. Small RNAs derived from herbs regulate mammalian gene expression in a sequence-specific manner, and thus are a superior novel class of herbal drug components that hold great potential as oral gene-targeted therapeutics, highlighting the important role of herbgenomics in their development.

[Effect of Flavonoids from Wang Zaizi on Adjuvant Arthritis in Rats and Its Mechanism].

OBJECTIVE: The therapeutic effect and mechanism of total flavonoids in Isodon amethystoides (Ben-th) Cy Wu et Hsuan (TFIA) on adjuvant arthritis (AA) were investigated. METHODS: AA model rats were set and complete Freund's adjuvant injection,randomly divided into 4 groups: AA group,AA+TFIA 50 mg/kg group,AA+TFIA 100 mg/kg group,AA+TFIA 150 mg/kg group,and each group has 10 rats. Blank control group was set without modeling (n=10). Four days post-modeling rats in each TFIA groups were treated once a day with TFIA at 50 mg/kg,100 mg/kg and 150 mg/kg for 24 d,and rats in blank control and AA groups were given saline as control. At the 12th day,16th day,20th day and 24th day of treatment,the effect of TFIA on AA rats was evaluated by rat arthritis score. Then the rats were sacrificed on the 24th day of treatment,and the synovial tissue of rats was isolated and the fibroblast-like synoviocytes (FLS) were primary cultured. The expressions of IL-1 in FLS was detected by ELISA,the FLS proliferation activity was detected by MTT assay,and the expression of miR-152,ß-catenin and cyclin D1 gene (ccnd1) were detected by real time qPCR. MiR-152 mimics and NC mimics (control) were transfected into FLS in AA rats,and miR-152 inhibitors and NC inhibitors (control) were transfected into FLS in AA+TFIA 100 mg/kg group rats. The expressions of miR-152,ß-catenin, ccnd1, IL-1 and FLS proliferation were detected 36 h post-transfection. RESULTS: TFIA significantly inhibited the arthritis socre of rats and the expressions of ß-catenin, ccnd1, IL-1 and the proliferation of FLS in AA rats (P<0.05). There was no significant difference between the dose groups,all of which were significant when compared with the blank control group (P<0.05). Compared with the control group,the expression of miR-152 in AA group was significantly decreased (P<0.05). After transfection of miR-152 mimics into AA FLS,overexpression of miR-152 significantly inhibited the expressions of ß-catenin, ccnd1, IL-1 and the proliferation of FLS (P<0.05). After transfection of miR-152 inhibitors into FLS from AA+TFIA 100 mg/kg group,inhibition of miR-152 significantly promoted the expressions of ß-catenin, ccnd1, IL-1 and the proliferation of FLS. CONCLUSION: TFIA has a certain therapeutic effect on AA rats via the up-regulation of miR-152 expression,possibly affecting the classical Wnt signaling pathway.

[Molecular mechanism of total flavonoids in Isodon amethystoides on adjuvant arthritis in rats].

Our preliminary study showed that the total flavonoids in Isodon amethystoides(TFIA), a local medicinal herb in Suzhou, had a certain therapeutic effect on adjuvant arthritis, and this therapeutic effect may be achieved through the up-regulation of miR-152 expression. In this paper, the molecular mechanism of TFIA on the pathogenesis of adjuvant arthritis(AA) rats was further studied. AA rats were prepared with complete Freund's adjuvant, and then treated with TFIA by intragastric administration. Real-time qPCR was used to detect the effects of TFIA on the negative regulatory loop of miR-152, methylase DNMT1 and methyl-CpG binding protein MeCP2 in fibroblast like synoviocytes(FLS) of AA rats, as well as the effects of TFIA on the classic Wnt signaling pathway and the expression of fibronectin gene in AA rats. Intragastric administration of TFIA significantly inhibited the expression of DNMT1 and reversed the negative regulatory loop composed of miR-152, DNMT1 and MeCP2 in the pathology of AA rats. After transfection of miR-152 inhibitors into the FLS in treatment group, DNMT1 expression was significantly restored. TFIA significantly up-regulated the expression of SFRP4 and inhibited the expression of ß-catenin, C-myc and ccnd1, the key genes of canonical Wnt signaling pathway. TFIA also significantly inhibited the expression of fibronectin, an AA gene. The effect of TFIA on the expression of SFRP4, ß-catenin, C-myc, ccnd1 and fibronectin was reversed after transfection with miR-152 inhibitors in the treatment group FLS. TFIA may inhibit the DNMT1 expression, up-regulate the SFRP4 expression, inhibit the expression of classical Wnt signaling genes ß-catenin, C-myc, and ccnd1 as well as the RA gene fibronectin expression through the up-regulation of miR-152 expression.

Lipid-soluble green tea extract: Genotoxicity and subchronic toxicity studies.

To assess the potential safety of lipid soluble green tea extract, also referred to as lipid soluble tea polyphenols (LSTP), a series of genotoxicity tests were conducted, including an Ames, in vivo mouse micronucleus, and in vivo mouse sperm abnormality test. The toxicity of LSTP was evaluated in 90- and 30-day feeding studies. LSTP did not show mutagenic activity in the Ames test and no genotoxic potential in the in vivo assays at doses up to 10 g/kg body weight (bw). In the 90-day feeding study, LSTP was given in the diet at levels providing 0, 0.125, 0.25, or 0.50 g/kg bw/day. No significant effects were noted on body weight, food consumption, hematology, clinical chemistry, organ weights, and histopathological examination. The no-observed-adverse-effect level (NOAEL) was therefore considered to be 0.50 g/kg bw/day, the highest dose tested. Likewise, dosing of SD rats by gavage for 30 days also showed no adverse effects of growth, hematology, clinical chemistry, organ weights, or histopathology at doses of 0.58, 1.17, and 2.33 g/kg bw/day. The NOAEL in the 30-day study was considered to be the highest dose tested. These data provide evidence to support the safe use of LSTP in food.

[Flavonoids of Echinps latifolius suppress Wnt signaling in adjuvant arthritis rats].

The role of flavonoids of Echinps latifolius (FELT) in Wnt signaling was investigated in adjuvant arthritis (AA) rats. The therapeutic effects of FELT on AA rats were detected by rat arthritis score and MTT. The effect of FELT gavage treatment on the Wnt signaling key gene ß-catenin, C-myc and cyclin D1 in synovium from AA rats was detected by Real-time qPCR, and the effects of FELT gavage treatment on the upstream negative regulation gene SFRP 1,2,4,5 in synovium from AA rats were detected by Real-time qPCR. The results showed that FELT gavage treatment significantly inhibited arthritis score and MTT values in AA rats, significantly inhibited the expression of the Wnt signaling gene ß-catenin, C-myc and cyclin D1, significantly up-regulated the expression of the up- stream negative regulation gene SFRP 1,2,4. FELT has a better therapeutic effect for AA rats.

[Effect of pulchinenoside on FZD8 expression of adjuvant arthritis rats].

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.

[Pulchinenoside control MeCP2 expression in FLS from RA model rats].

The role of pulchinenoside (PULC) in the regulation of MeCP2 expression was investigated in RA model rats. Adjuvant arthritis rats were used as RA model rats, and fibroblast-like synoviocytes (FLS) from the RA model rats were cultured. The effect of 100 mg x kg(-1) PULC gavage treatment on the MeCP2 expression and the effect of MeCP2 siRNA on the expression of SFRP2 and ß-catenin were detected by real time qPCR and Western blotting. The role of PULC in the FLS proliferation was detected by MTT. The results showed that the MeCP2 expression was down-regulated, the SFRP2 expression was up-regulated and the FLS proliferation was inhibited in FLS after therapy. MeCP2 siRNA significantly inhibited the MeCP2 expression, up-regulated the SFRP2 expression and inhibited the ß-catenin expression in FLS from RA model rats. PULC may increase the SFRP2 expression, inhibit the Wnt signaling and inhibit the FLS proliferation in FLS from the RA model rats by inhibiting the MeCP2 expression.
