Exo-M7 or Exo-M1 could increase BC cell proliferation and enhance EMT in nude mouse. Exo-M7 and Exo-M1 could accelerate the transformation of NFs into CAFs and promote the recruitment of CAFs in MCF-7. Transfection of miR-146a could promote the transformation of NFs into CAFs and promote cell invasion and migration of MCF-7 cells. As a target gene of miR-146a, TXNIP could inhibit the activation of CAFs. miR-146a overexpression or TXNIP silence enhance the activation of Wnt signal pathway. CONCLUSION BC-derived exosomes promote the activation of CAFs through miR-146a/TXNIP axis to activate Wnt pathway, which in turn enhances invasion and metastasis of BC cells. The hepatitis C virus (HCV) is a major cause of liver diseases ranging from liver inflammation to advanced liver diseases like cirrhosis and hepatocellular carcinoma (HCC). HCV infection is restricted to the liver, and more specifically to hepatocytes, which represent around 80% of liver cells. The mechanism of HCV entry in human hepatocytes has been extensively investigated since the discovery of the virus 30 years ago. The entry mechanism is a multi-step process relying on several host factors including heparan sulfate proteoglycan (HSPG), low density lipoprotein receptor (LDLR), tetraspanin CD81, Scavenger Receptor class B type I (SR-BI), Epidermal Growth Factor Receptor (EGFR) and Niemann-Pick C1-like 1 (NPC1L1). Moreover, in order to establish a persistent infection, HCV entry is dependent on the presence of tight junction (TJ) proteins Claudin-1 (CLDN1) and Occludin (OCLN). In the liver, tight junction proteins play a role in architecture and homeostasis including sealing the apical pole of adjacent cells to form bile canaliculi and separating the basolateral domain drained by sinusoidal blood flow. In this review, we will highlight the role of liver tight junction proteins in HCV infection, and we will discuss the potential targeted therapeutic approaches to improve virus eradication. Successful reproductive cloning depends on obtaining intact donor nuclei from viable cells, ideally isolated by tissue biopsy of a living donor. However, owners and veterinarians often freeze deceased animals, which eventually causes damage to cellular micro-organelles due to the formation of intracellular water crystals. In the present study, we have reported the production of viable cloned puppies using donor nuclei of cells obtained from frozen carcasses. Five cases of deceased and frozen canine specimens were presented to be cloned. Skin fibroblast cell lines were successfully established for four specimens. Significant longer time was needed for the cell growth from frozen tissues (4 days) to reach 80% confluency compared to fresh tissue and frozen tissues frozen for 1- or 2-days. Similarly, SA-βgal positive cells (death cells) were significantly higher in frozen cells for 2- or 4- days compared to samples from fresh or frozen (1 day) sources. The cloning efficiency (CE) and the pregnancy rates (PR) of frozen cells were lower than those obtained from fresh or living donors (CE 2.4 ± 1.8% vs. 0.6 ± 0.3%, PR 21.7 ± 16.1% vs. 7.7 ± 5.3% for fresh vs. frozen, respectively). Here we demonstrate is the possibility to produce healthy offspring from cell lines obtained from frozen tissue collected post-mortem. Biomarkers have the potential to become central to the clinical evaluation and monitoring of patients with chronic fibrosing interstitial lung diseases with a progressive phenotype. Here we summarize the current understanding of putative serum, bronchoalveolar lavage fluid and genetic biomarkers in this setting, according to their hypothesized pathobiologic mechanisms evidence of epithelial cell dysfunction (eg, Krebs von den Lungen-6 antigen), fibroblast proliferation and extracellular matrix production/turnover (eg, matrix metalloproteinase-1), or immune dysregulation (eg, CC chemokine ligand 18). While most of the available data comes from idiopathic pulmonary fibrosis, the prototypic progressive fibrosing interstitial lung disease, there are data available in the broader patient population of chronic fibrosing interstitial lung diseases. While a number of these biomarkers show promise, none have been validated. In this review article, we assess both the status of proposed biomarkers for chronic fibrosing lung diseases with a progressive phenotype in predicting disease risk or predisposition, diagnosis, prognosis and treatment response, and provide a direct comparison between idiopathic pulmonary fibrosis and other chronic fibrotic interstitial lung diseases. We also reflect on the current clinical usefulness and future direction of research for biomarkers in the setting of chronic fibrosing interstitial lung diseases with a progressive phenotype. Community acquired pneumonia is a leading cause of mortality in the United States. Along with predisposing comorbid health status, age is an independent risk factor for determining the outcome of pneumonia. Research over the last few decades has contributed to better understanding the underlying immunodysregulation and imbalanced redox homeostasis tied to this aged population group that increases susceptibility to a wide range of pathologies. Major approaches include targeting oxidative stress by reducing ROS generation at its main sources of production which includes the mitochondrion. Mitochondria-targeted antioxidants have a number of molecular strategies that include targeting the biophysical properties of mitochondria, mitochondrial localization of catalytic enzymes, and mitigating mitochondrial membrane potential. Results of several antioxidant studies both in vitro and in vivo have demonstrated promising potential as a therapeutic in the treatment of pneumonia in the elderly. More human studies will need to be conducted to evaluate its efficacy in this clinical setting. Wound infections associated with multidrug-resistant (MDR) bacteria are one of the important threats to public health. Bacteriophage (phage) therapy is a promising alternative or supplementary therapeutic approach to conventional antibiotics for combating MDR bacterial infections. In recent years, significant effort has been put into the development of phage formulations and delivery methods for topical applications, along with preclinical and clinical uses of phages for the treatment of acute and chronic wound infections. This paper reviews the application of phages for wound infections, with focus on the current status of phage formulations (including liquid, semi-solid and liposome-encapsulated formulations, phage-immobilized wound dressings), safety and efficacy assessment in clinical settings and major challenges to overcome. The global burden of bacterial infections is rising due to increasing resistance to the majority of first-line antibiotics, rendering these drugs ineffective against several clinically important pathogens. Limited transport of antibiotics into cells compounds this problem for gram-negative bacteria that exhibit prominent intracellular lifecycles. Furthermore, poor bioavailability of antibiotics in infected tissues necessitates higher doses and longer treatment regimens to treat resistant infections. Although emerging antibiotics can combat these problems, resistance still may develop over time. Expanding knowledge of host-pathogen interactions has inspired research and development of host-directed therapies (HDTs). HDTs target host-cell machinery critical for bacterial pathogenesis to treat bacterial infections alone or as adjunctive treatment with traditional antibiotics. Unlike traditional antibiotics that directly affect bacteria, a majority of HDTs function by boosting the endogenous antimicrobial activity of cells and are consequently less prone to bacterial tolerance induced by selection pressure. Therefore, HDTs can be quite effective against intracellular cytosolic or vacuolar bacteria, which a majority of traditional antibiotics are unable to eradicate. However, in vivo therapeutic efficacy of HDTs is reliant on adequate bioavailability. Particle-based formulations demonstrate the potential to enable targeted drug delivery, enhance cellular uptake, and increase drug concentration in the host cell of HDTs. Ruxotemitide This review selected HDTs for clinically important pathogens, identifies formulation strategies that can improve their therapeutic efficacy and offers insights toward further development of HDTs for bacterial infections. We previously reported on a novel fibrin matrix having increased viscoelastic strength derived from human plasma fibronectin (pFN) and γγ'-fibrinogen (γγ'-FI). Here we use high pressure size exclusion chromatography (HPSEC) and dynamic light scattering (DLS) to observe interactions between the linearly extended conformation of γγ'-FI and random coiled pFN. Distinct γγ'-FIpFN subpopulations were fractionated where each maintained unique retention times when individually reprocessed by HPSEC. The hydrodynamic sizes by HPSEC and DLS for these reprocessed subfractions were intermediate to that of pure γγ'-FI and pFN. SDS-PAGE analysis showed that the majority of these subfractions contained intact γγ'-FI and pFN. Importantly, after disruption and isolation using Gelatin Sepharose affinity chromatography, new complexes rapidly formed between pFN and γγ'-FI when mixed back together. This also occurred in analogous mixing experiments between Des-Aα γγ'-FI and pFN where both Aα-chains are reduced by about 15 kDa due to proteolysis. The reversible complexation observed using HPSEC and DLS was not observed in prior studies using SPR indicating that unrestricted freedom of motion is needed to efficiently form these compact associations. The presence of a γ' chain, but not the carboxy terminal portions of either Aα chain are needed for complexation phenomena between pFN and γγ'-FI. Biopolymer composites based on two types of chitosan (chitosan succinate and low-molecular weight chitosan) with single-walled carbon nanotubes (SWCNT) were created by laser printing. SWCNT have good dispersibility in chitosan solutions and therefore, can form relatively homogeneous films that was shown in scanning electron microscopy images. For the studies film composites were formed under the action of laser radiation on aqueous dispersion media. Study of the nonlinear optical process during the interaction of laser radiation with a disperse media has shown that low-molecular chitosan has a large nonlinear absorption coefficient of 17 cm/GW, while the addition of SWCNT lead to a significant increase up to 902 cm/GW. The threshold intensity for these samples was 5.5 MW/cm2 with nanotubes. If intensity exceeds the threshold value, nonlinear effects occur, which, in turn, lead to the transformation of a liquid into a solid phase. Characterization of films by FTIR and Raman spectroscopy indicated arising molecular interactions between chitosan and SWCNT detected as a small frequency shift and a change in the shape of radial breathing mode (RBM). The results indicate the possibility using aqueous dispersion media based on chitosan and SWCNT to create three-dimensional films and scaffolds for tissue engineering by laser printing.
