Infantile haemangiomas (IH) are the most common soft-tissue tumours in infants. Several studies have demonstrated the importance of circular RNA (circRNA) for the regulation of various cancer cells. The present study aims to evaluate the functions and molecular mechanisms of circATP5SL in IH progression. In this study, we found that circATP5SL is significantly dysregulated in IH. We conducted Transwell, MTT, and flow cytometry analysis to evaluate the role of circATP5SL in IH cell proliferation, invasion, migration, and apoptosis. Meanwhile, by using subcellular distribution detection, as well as dual-luciferase reporter test and RIP analysis, it has been confirmed that miR-873-5p directly binds to the 3'UTR of IGF1R mRNA, thereby inhibiting the expression of IGF1R. Besides, circATP5SL promoted IGF1R expression by directly adsorbing miR-873-5p, an IGF1R inhibitor, thereby promoting cellular invasion, proliferation, and migration as well as inhibition of apoptosis. In summary, our study suggests that circATP5SL promotes IH progression by regulating IGF1R expression through adsorption of miR-873-5p, elucidating circATP5SL as a promising therapeutic target for the prognostication and treatment of IH.
There remains a scarcity of both autografts and allografts for tracheal transplantation after long-segmental resection. Subsequently, tissue engineering has become a promising alternative for tracheal transplantation, which requires successful
chondrogenesis.

To optimize the protocol for
chondrogenesis using the pig-derived whole Umbilical Cord (UC) as the starting material, it must be performed without using the UC-multipotent stromal cell (MSCs) isolation procedure. Nevertheless, chondrogenic induction is performed under a variety of conditions; with or without TGF-β1 at different concentrations, and also in combination with either a rotatory or hollow organ bioreactor. The engineered explant sections were analyzed using various histochemical and immunohistochemical stains to assess the expression of chondrocyte markers. Cell viability was determined through use of the APO-BrdU TUNEL assay kit.

The results showed that culture conditions induced heterogeneous chondrogenesis in various compartments of the UC. Moreover, explants cultured with 10 ng/ml TGF-β1 under hypoxic (1% O
) in combination with a bioreactor, significantly enhanced the expression of aggrecan and type II collagen, but were lacking in the production of Glycosaminoglycans (GAGs), as evidenced by alcian blue staining. We speculated that whole segment UCs allowed for the differentiation into premature chondrocytes in our tissue-engineered environments.

This study has provided exciting preliminary evidence showing that a stem cell-rich UC wrapped around an anatomical tracheal scaffold and implanted in vivo can induce nodes of new cartilage growth into a structurally functional tissue for the repairing of long-segmental tracheal stenosis.

Indeed, repair of damaged peripheral nerves is predominantly mediated by type 2 immune responses. Given that helminth parasites induce type 2 immune responses in hosts, we wondered whether helminths or helminth-derived molecules might have the potential to improve peripheral nerve repair. Here, we demonstrated that schistosome-derived SJMHE1 promoted peripheral myelin growth and functional regeneration via a macrophage-dependent mechanism and simultaneously increased the induction of M2 macrophages. Our findings highlight the therapeutic potential of schistosome-derived SJMHE1 for improving peripheral nerve repair.Progestin administration serves as the optimal conservative treatment method for women with endometrial cancer or precancer lesions who want to preserve fertility. However, there are still at least 30% of patients in which progestin resistance occurs. LASS2 (Ceramide Synthase 2) has been reported to be involved in chemotherapy resistance, whether it also plays a role in progestin resistance is not clear. Here, we explored the detailed mechanism by which Nrf2/LASS2 contributes to progestin resistance and disease progression.
IHC assays were performed to estimate the expression pattern of Nrf2 and LASS2. Moreover, it bears three antioxidant response elements (ARE) in the promoter region of LASS2 gene, therefore, Luciferase assays were performed to determine if Nrf2 regulates LASS2 by binding with these ARE sequence. Western Blot assays were used to determine the expression of Nrf2 and LASS2 protein among various endometrial cell lines. Relative mRNA expression levels were detected by RT-PCR. Cellular growth wahe prognosis of endometrial cancer but also serve as a potential therapeutic target.We have recently demonstrated that reactive oxygen species (ROS) scavengers ameliorate mechanical allodynia in a rat model of cancer-induced bone pain (CIBP). In the present study, we investigated anti-nociceptive effect of Nox inhibitor apocynin in CIBP in rats. Mechanical allodynia was assessed by Von Frey tests in sham and CIBP group of rats. Western blotting and immunofluorescence technique were conducted to assess the expression levels and cellular localization of Nox2. Results illustrated that after intra-tibial implantation with tumor cells, Nox2 and ROS were both up-regulated in the spinal cord of rats. Injection of apocynin could dose-dependently decrease the abundance of Nox2 and inhibit the development of CIBP. Furthermore, pretreatment with the apocynin could delay the development of CIBP. This study for the first time proved that Nox2 inhibitors could downregulate the production of ROS in CIBP rats, which highlights the fact that Nox inhibitor is an important therapeutic option for CIBP and that, precise targeting inhibitor of different subtypes of Nox enzymes is needed to developed in future.
Postoperative pancreatic fistula (POPF) is a serious complication after gastrointestinal or pancreatic surgery. Despite intensive investigations, the occurrence has not significantly decreased in the past decades. The aims of this study were to clarify the pathophysiology of POPF and establish the preventive measures using multilayered fibroblast sheets.

We developed a pancreatic fistula (PF) model of rat with transection of the splenic duct and surrounding pancreatic parenchyma. Multilayered fibroblast sheets prepared from tails were autologously transplanted to this model. The preventive effect was biochemically and histologically evaluated by measuring the ascitic levels of pancreatic enzymes and conducting immunohistochemistry and real-time polymerase chain reaction analyses of pancreatic tissue. Findings were compared to those obtained with acellular materials simply sealing the wound.

In the PF model, the ascitic levels of pancreatic enzymes were transiently up-regulated. Inflammation and necrosis were histologically observed in a wide range. Islets were damaged even in remote areas. Transplantation of multilayered fibroblast sheets dramatically reduced the ascitic leakage of enzymes, suppressed inflammation, and broadly preserved the islets. Compared with acellular materials, these sheets offered superior prevention of cellular activity through the spaciotemporal regulation of fibrosis and angiogenesis. Notably, the leakage hole appeared to have been plugged with the fibrotic matrix, which might have been the most crucial mechanism minimizing pancreatic damage.

The autologous transplantation of multilayered fibroblast sheets significantly prevented PF and protected the pancreas, underscoring the potential utility of this approach for POPF prevention.

To explore the molecular mechanism of umbilical cord blood mesenchymal stem cells (UCBMSCs) in the treatment of advanced osteoarthritis pain.

Normal healthy rats were selected to establish advanced osteoarthritis (OA) model, and the rats were randomly divided into control group, intravenous group, intracavitary group and intrathecal group. The intravenous group received intravenous injection of UCBMSCs, intracavitary group received intra-articular injection of UCBMSCs, and intrathecal group received subarachnoid injection of UCBMSCs. The pain behavior and serum pro-inflammatory factor levels were evaluated before and after treatment. microRNA-29a-3p and FOS mRNA in spinal dorsal horn was detected using qPCR, the phosphorylation of c-fos protein and NR1, NR2B, ERK and PKCg was detected using Western blot, and the level of LncRNA H19 was detected using qPCR.

LncRNA H19 was enriched in the exosomes of UCBMSCs. microRNA-29a-3p was the target gene of LncRNA H19, while FOS was the downstream target of microRNA-29a-3p. Pain and inflammation of rats in the intrathecal group improved best, and the phosphorylation levels of c-fos and NR1, NR2B, ERK and PKCg in the spinal dorsal horn of the intrathecal group decreased. LncRNA H19 regulated the central sensitization of astrocytes through microRNA-29a-3p/FOS axis.

Intrathecal injection of umbilical cord blood mesenchymal stem cells can improve the pain and central sensitization of advanced osteoarthritis through LncRNA H19/microRNA-29a-3p/FOS axis.

We used an in vitro TGF-β1 induced podocyte EMT model and an in vivo rat focal segmental glomerulosclerosis (FSGS) model to uncover the mechanism underlying the protective effect of triptolide (TP) on podocytes. We found that TP could reverse the podocyte EMT process and upregulate the expression of TET2 in the TGF-β1-induced podocyte injury model. Bisulfite amplicon sequencing (BSAS) showed TP could alter the methylation status at some specific sites of the medium CpG density region in the promoters of NEPH1 and nephrin, two main markers of the podocyte slit diaphragm. Knockdown of TET2 with shRNA lentivirus (Lv) leads to high methylation of the promoters of NEPH1 and nephrin such that their expression can not return to normal levels, even after treatment with TP. In vivo, we found that TP could protect against podocyte injury in the FSGS rat and increase TET2 expression. These results suggested TET2-mediated DNA demethylation may be partly involved in podocyte injury. We believe these findings can help uncover a novel molecular mechanism of TP in alleviating podocyte-associated glomerular diseases.MiR-22-3p has been reported to be down-regulated in several cancers, but its expression pattern and roles in lung cancer is unclear. Given the crucial role of microRNAs in cancer progression, we examined the expression and function of miR-22-3p in lung adenocarcinoma. MiR-22-3p expression in lung cancer tissues and cell lines was measured by qRT-PCR. Cell proliferation was measured by WST-1 and colony formation assays were used to reveal the role of miR-22-3p in lung cancer in vitro. MiR-22-3p was notably down-regulated in lung cancer tissues as compared to normal lung tissues, but it was not associated with the clinical characteristics of tumor stage, differentiation and patient's smoking status. NVP-AEW541 cost Colony formation ability and cell proliferation were suppressed by miR-22-3p mimics in lung cancer cell lines. Mechanistically, miR-22-3p mimics could reduce MET and STAT3 protein expression and induce apoptosis as measured by PARP protein. We conclude that miR-22-3p may play a tumor suppressor role via inhibiting MET-STAT3 signaling and have potential to be a therapeutic target and biomarker in lung adenocarcinoma.
