Development of a multi-technique analytical strategy for the thermal stability assessment of recombinant humanized type III collagen. (PubMed, Anal Methods) - "Key modification sites (e.g., N425, M131, and P144/P132) were successfully localized and found to be enriched in thermally sensitive regions N- and C-termini...The analytical strategy developed in this study enables multidimensional and correlative assessment of protein stability. It not only provides a key stability-indicating methodology for rhCol III but also offers an analytical reference framework for stability studies, process optimization, and quality control of biomacromolecular materials."

Placental plasminogen activator inhibitor 1 is induced by platelet-derived TGF-β independently of TGF-β receptor 3 and is upregulated in preeclampsia. (PubMed, Mol Hum Reprod) - "The upregulation of SERPINE1 was blocked to control levels with the TGF-β inhibitor P144, whereas silencing of TGFBR3 had no effect. Our results suggest that platelet-derived factors induce placental PAI-1 expression independently of TGF-β receptor 3. Increased maternal platelet activation may contribute to significantly upregulated placental PAI-1 and perivillous fibrin deposits in preeclampsia."

Unveiling metastable intermediates of block copolymer self-assembly in colloids via graphene liquid cell imaging. (PubMed, J Colloid Interface Sci) - "In this study, we use in-situ graphene liquid cell (GLC) transmission electron microscopy to directly visualize the phase separation dynamics of two vesicle-forming block copolymers, PS154-b-PAA49 and PS144-b-PAA22, in a DMF/water mixture...Molecular dynamics simulations and deep-learning-assisted image analysis support these observations, demonstrating that "self-hollowing" arises from the interplay between solvent-selective block interactions and local density fluctuations. By providing a high-resolution kinetic map of these morphological transitions, this work offers a clearer understanding of how to control BCP assembly to design precise porous nanomaterials."

Bmscs loaded exosome hydrogel promotes the repair of rotator cuff injury in rats in vivo. (PubMed, Sci Rep) - "After the extraction and identification of mesenchymal stem cell-derived exosomes, 60 male Sprague-Dawley rats were randomly divided into five groups (n = 12 per group): control (untreated), repair-alone, GelMA (hydrogel only), BMSC-Exos (hydrogel + BMSC-Exos), and BMSC-Exos + TGF-β1 inhibited (hydrogel + BMSC-Exos + TGF-β1 inhibitor P144)...BMSC-Exos were successfully isolated and characterized. Biomechanical tests showed that the BMSC-Exos group exhibited significantly higher maximum failure load and stiffness compared with the repair-alone, GelMA, and BMSC-Exos + TGF-β1 inhibited groups (all P < 0.05), reaching levels similar to the normal control. Histological scoring revealed that the BMSC-Exos group had better collagen fiber continuity, parallelism, density, and fewer inflammatory cells and blood vessels at the tendon-bone interface. Gene expression analysis demonstrated that the BMSC-Exos group significantly upregulated the mRNA levels..."

Clinical significance of SLIT2/ROBO1 expression in prostate cancer (PubMed, Zhonghua Bing Li Xue Za Zhi) - "The expression was significantly up-regulated in prostate cancer tissues with lymph node metastasis (P<0.01) and T3 stage.In addition, COX regression univariate analysis showed that age, preoperative PSA level, Gleason and ISUP scores, T stage, lymph node metastasis and ROBO1 protein expression status were correlated with postoperative biochemical recurrence.COX regression multivariate analysis showed that ROBO1 high expression, age, preoperative PSA value and T stagewere risk factors for the prognosis of prostate cancer (P<0.05).The results of cell experiments showed that ROBO1 promoted the proliferation, migration and invasion of prostate cancer cells.The expression of TGF-β/SMAD was decreased after ROBO1 knockdown and SLIT2/ROBO1 inhibitor (P144)treatment, respectively. The high expression of SLIT2 and ROBO1 is associated with the progression and differentiation of prostate cancer.The high expression of ROBO1 is a risk factor for biochemical recurrence of..."

Structures of Mature and Urea-Treated Empty Bacteriophage T5: Insights into Siphophage Infection and DNA Ejection. (PubMed, Int J Mol Sci) - "Atomic models of the head, connector complex, tail tube, and tail tip were built for mature T5, and atomic models of the connector complex, comprising the portal protein pb7, adaptor protein p144, and tail terminator protein p142, were built for urea-treated empty T5. Our findings revealed that the aforementioned proteins did not undergo global conformational changes before and after DNA ejection, indicating that these structural features were conserved among most myophages and siphophages. The present study elucidates the underlying mechanisms of siphophage infection and DNA ejection."

Omeprazole induces profibrotic gene expression in rat kidney: implication of TGF-β/Smad signaling pathway.

Collectively, the current findings demonstrate that omeprazole has the ability to promote the expression of the profibrotic genes CTGF and TIMP-1 in a ROS and TGF-β dependent manner. The present study suggests the co-use of ROS scavenger to improve the therapeutic use of the PPI omeprazole."

Adherence to inhaled corticosteroids in pregnant asthmatics (BTS WM 2022) - "P144 Figure 1 Pick up rates of ICS treatmentConclusion Poor compliance to ICS treatment in asthma is not confined to pregnant asthmatics and may be a historical finding in these patients. However, an increase in ICS adherence following clinic review indicates that education and reinforcement of medication safety and importance of adherence to treatment is essential in this cohort and will undoubtedly improve clinical outcomes and reduce the risk of exacerbations.Patient concerns relating safety of inhaled therapies in pregnancy should be addressed early to improve patient outcomes in the high risk group.Trends to poor compliance in the absence of clinic review has led to the evolution of monthly appointments until review until delivery, rather than early discharge."

Bombyx mori can synthesize ascorbic acid through the l-gulose pathway to varying degrees depending on developmental stage.

Thus, Bombyx mori can synthesize AsA through the l-gulose pathway, albeit with low activity, and this synthesis ability varies with developmental stages."
