Research progress of probiotics intervening osteoporosis through intestinal tract / 中国医师杂志

Osteoporosis (OP) is a systemic bone disease characterized by decreased bone density and damage to bone microstructure, leading to brittle fractures. It is a multifactorial disease that is more common in postmenopausal women, and its high incidence and serious complications are receiving increasing attention. Currently, clinical anti-osteoporosis drugs are mainly divided into two categories: inhibiting bone resorption and promoting bone formation, including bisphosphonates, calcitonin and estrogen, etc. But the side effects and high economic cost of drugs limit the scope of their use to some extent. In recent years, the effect of intestinal flora on bone health, especially on osteoporosis, has become a potential new target for regulating bone density. Probiotics belong to intestinal flora and are defined as living microorganisms. They have initially shown good efficacy in the treatment of some bone metabolic diseases, suggesting that intestinal flora can be used as a potential target for the prevention and treatment of osteoporosis and the application of probiotics as a new therapeutic method for osteoporosis. This paper mainly reviews the relevant studies on probiotics and osteoporosis, shows the latest research progress of probiotics intervention in OP, clarifies the relevant action mechanism of probiotics intervention in OP through intestinal tract, and analyzes the research status and prospect of probiotics treatment in OP.

DNA sensor cGAS-mediated immune recognition

The host takes use of pattern recognition receptors (PRRs) to defend against pathogen invasion or cellular damage. Among microorganism-associated molecular patterns detected by host PRRs, nucleic acids derived from bacteria or viruses are tightly supervised, providing a fundamental mechanism of host defense. Pathogenic DNAs are supposed to be detected by DNA sensors that induce the activation of NFκB or TBK1-IRF3 pathway. DNA sensor cGAS is widely expressed in innate immune cells and is a key sensor of invading DNAs in several cell types. cGAS binds to DNA, followed by a conformational change that allows the synthesis of cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) from adenosine triphosphate and guanosine triphosphate. cGAMP is a strong activator of STING that can activate IRF3 and subsequent type I interferon production. Here we describe recent progresses in DNA sensors especially cGAS in the innate immune responses against pathogenic DNAs.

Cloning and expression of human interleukin-26 in Escherichia coli / 生物工程学报

To clone human interleukin-26 (hIL-26) and express it in E. coli efficiently. Two pairs of primers were synthesized according to the hIL-26 gene reported on GenBank. The hIL-26 gene was cloned by nest PCR following the first round RT-PCR from human peripherial blood monocytes total RNA, and then the PCR product was cloned into pMD18-T vector. Colony PCR, restriction analysis and sequence analysis showed that the gene cloned was the same as the reported hIL-26. The recombinant was cut with BamHI and EcoR I to obtain the hIL-26 fragment, and then the fragment was inserted into pBV220 which was cut with the same enzymes. The recombinant expression vector was induced to express hIL-26 at 42 degrees C, SDS-PAGE analysis showed that the recombinant protein accounted for up to 20% of the whole protein of E. coli, and the protein was also confirmed by Western blotting. Purity of the protein was found to be above 90% after purified with molecular sieve. After renaturalized with glutathione buffer, the promoting effect of it on the production of IFN-y in PBMC was detected by RT-PCR. A recombinant bacterial strain for expressing hIL-26 with biological activity was constructed successfully.

Correlation of thrombosis with increased platelet turnover in essential thrombocythemia / 中国实验血液学杂志

This study was aimed to investigate the correlation of thrombosis with increased platelet turnover in essential thrombocythemia. According to presence or absence of thrombosis, 26 patients with ET were divided into two groups. Reticulated platelets (RP) were measured by flow cytometry and 26 healthy volunteers were selected as healthy controls. The ET patients with thrombosis were treated with hydroxyurea and interferon-alpha. The results demonstrated that the ET patients with thrombotic events had a significantly higher RP percentage (14.8% +/- 7.2%) than that in both asymptomatic ET patients (4.5% +/- 2.3%) and normal control (3.3% +/- 1.5%), (P < 0.05); the RP percentage in asymptomatic ET patients did not differ significantly from controls. ET patients with thrombosis also had a significantly higher absolute RP (ARP) count than those in ET patients without thrombosis [(176 +/- 37) x 10(9)/L vs (46 +/- 12) x 10(9)/L]. The ET patients with thrombosis were successfully treated with hydroxyurea plus INF-alpha, the RP percentage and ARP counts obviously reduced. In conclusion, when the ET patients had thrombotic events, those patients had a significantly higher RP percentage and ARP compared with patients without thrombosis and healthy controls. The ET patients with thrombosis were successfully treated with hydroxyurea plus INF-alpha.
