Exosomes containing circSCP2 in colorectal cancer promote metastasis via sponging miR-92a-1-5p and interacting with PTBP1 to stabilize IGF2BP1.

Exosomes have emerged as significant biomarkers for multiple diseases, including cancers. Circular RNAs (circRNAs), abundant in exosomes, are involved in regulating cancer development. However, the regulatory function and the underlying molecular mechanism of hsa_circ_0006906 (circSCP2) in colorectal cancer (CRC) metastasis remain unclear.

Enhancing the Electrochemical Energy Storage of Metal-Organic Frameworks: Linker Engineering and Size Optimization.

The electric conductivity and charge transport efficiency of metal-organic frameworks (MOFs) dictate the effective utilization of built-in redox centers and electrochemical redox kinetics and therefore electrochemical performance. Reticular chemistry and the tunable microcosmic shape of MOFs allow for improving their electric conductivity and charge transfer efficiency. Herein, we synthesized two Ni-MOFs (Ni-tdc-bpy and Ni-tdc-bpe) by the solvothermal reaction of Ni ions with 2,5-thiophenedicarboxylic acid (Htdc) in the presence of conjugated 4,4'-bipyridyl (bpy) and 1,2-di(4-pyridyl)ethylene (bpe) coligands, respectively.

Electrochemical Desaturation and β-Thiocyanation of Cyclic Amides.

The site-selective functionalization of cyclic amides provides an attractive protocol for the synthesis of valuable molecules. We report herein an electrochemical desaturation and β-thiocyanation of cyclic amides under external oxidant-free conditions. This method exhibits broad functional group tolerance, excellent selectivity, mild reaction conditions and can be applied for late-stage functionalization of bioactive molecules.

Effects of Prolactin Inhibition on Lipid Metabolism in Goats.

Prolactin (PRL) has recently been found to play a role in lipid metabolism in addition to its traditional roles in lactation and reproduction. However, the effects of PRL on lipid metabolism in liver and adipose tissues are unclear. Therefore, we aimed to study the role of PRL on lipid metabolism in goats.

Superior Capacitive Energy Storage Enabled by Molecularly Interpenetrating Interfaces in Layered Polymers.

Polymer dielectrics are essential for advanced electronics and electrical power systems, yet they suffer from low energy density (U) due to their low dielectric constant (K) and the inverse relationship between K and breakdown stength (E). Here a scalable approach utilizing the designed molecularly interpenetrating interfaces is presented to achieve all-organic dielectric polymers with high U and charge-dischage efficiency (η). Distinctive intermolecular interactions and microstructural changes, as demonstrated experimentally and theoretically, are introduced by the molecularly interpenetrating interfaces, resulting in simultaneous improvements in dielectric responses and mechanical strength while inhibiting electrical conduction - outcomes unattainable in conventional layered polymers.

Renal microangiopathy induced by lenvatinib in hepatocellular carcinoma: a case report and literature review.

Lenvatinib, a multi-target inhibitor of receptor tyrosine kinases, has been increasingly used in the treatment of advanced hepatocellular carcinoma (HCC). However, its association with renal adverse effects, including proteinuria and renal microvascular complications, was not fully understood in HCC patients. We reported a case of a 68-year-old male with a history of hypertension, diabetes mellitus, and hepatitis C virus (HCV) infection, diagnosed with primary HCC in 2015.

Energy Metabolite, Immunity, Antioxidant Capacity, and Rumen Microbiota Differences Between Ewes in Late Gestation Carrying Single, Twin, and Triplet Fetuses.

The objective of this study was to investigate the differences in the energy metabolites, immunity, antioxidant capacity, and rumen microbiota of ewes with different numbers of fetuses. Thirty healthy ewes were selected and divided into single- (SL, = 10), twin- (TL, = 10), and triplet-fetal (PL, = 10) ewes according to the number of fetuses. Sampling was carried out on days 21 (Q21) and 7 (Q7) before lambing.

Intermolecular Forces-Oriented Growth of MOF-on-MOF Heterostructures.

Well-controlled conjugation of distinct metal-organic frameworks (MOFs) with dissimilar components and structures into a multi-component MOF system is important for the design of myriad materials with structural complexity, integrated properties, and desired applications. Herein, we developed an interesting integration strategy that relies on intermolecular force, and which can overcome the difference in lattice parameters. The strategy uses the pre-formed MOF matrixes as seeds to direct the self-assembly of secondary MOF particles for the construction of hybrid MOFs.

Ground-to-air aircraft infrared image deblurring based on imaging degradation simulation.

The issue of infrared image deblurring has been a significant concern. However, in some specific scenes, the current mainstream deblurring algorithms based on optimization or deep learning fail to provide satisfactory results. Aiming to address the ineffectiveness of deep learning methods due to the low-cost datasets' unavailability for specific scenes, we innovatively propose a relatively simple full-chain imaging degradation simulation method using ground-to-air aircraft infrared imaging scene as an example, which considers the effects of blur and noise caused by the atmosphere, imaging system, target motion and detector.

Protein-Based 2D Nanoarchitectures Constructed by Heterochiral π-Stacking Dimerization of Helical Foldamers.

In this study, we focus on the designability and controllability of the interaction interface between secondary structures, and discover an important interface interaction between helical secondary structures by non-covalent synthesis along the helical axis. The formation of discrete heterochiral dimers consisting of left-handed helix and right-handed helix not only helps to discover nonclassical supramolecular chirality phenomena, but also enables controllable protein assembly. Highly ordered nanostructures were thus constructed using π-stacking dimerization of helical foldamers to control tetrameric avidin proteins.

MOGAT3-mediated DAG accumulation drives acquired resistance to anti-BRAF/anti-EGFR therapy in BRAFV600E-mutant metastatic colorectal cancer.

BRAFV600E-mutant metastatic colorectal cancer (mCRC) is associated with poor prognosis. The combination of anti-BRAF/anti-EGFR (encorafenib/cetuximab) treatment for patients with BRAFV600E-mutant mCRC improves clinical benefits; unfortunately, inevitable acquired resistance limits the treatment outcome, and the mechanism has not been validated. Here, we discovered that monoacylglycerol O-acyltransferase 3-mediated (MOGAT3-mediated) diacylglycerol (DAG) accumulation contributed to acquired resistance to encorafenib/cetuximab by dissecting a BRAFV600E-mutant mCRC patient-derived xenograft (PDX) model exposed to encorafenib/cetuximab administration.
