Because these affected individuals with classical features of VDEGS lacked a detectable pathogenic SCARF2 variant, genetic heterogeneity is likely. Our study shows the importance of performing genetic testing on individuals with the VDEGS "phenotype," either as a targeted gene analysis (SCARF2, ABL1) or WES/WGS. Additionally, individuals with the combination of arachnodactyly and blepharophimosis should undergo echocardiography while awaiting results of molecular testing due to the overlapping physical features of VDEGS and CHDSKM.The roles of long noncoding RNA (lncRNA) MCF2L-AS1 have been identified in colorectal cancer, however, its roles in lung cancer progression have never been revealed. Here, we found that lncRNA MCF2L-AS1 was highly expressed in lung cancer tissues and cells, especially in non-small cell lung cancer (NSCLC). Functional experiments showed that MCF2L-AS1 knockdown suppressed the cancer stem cell (CSC)-like traits of NSCLC cells through qRT-PCR, western blot, tumor-sphere formation, and ALDH activity detection. Additionally, bioinformatic assay combined with RNA pull down and luciferase reporter analysis confirmed that MCF2L-AS1 downregulated miR-873-5p level. Furthermore, miR-873-5p expression exhibited a lower level in lung cancer tissues and cells, and a negative correlation with MCF2L-AS1 expression in lung cancer tissues. click here Moreover, miR-873-5p inhibition partially reversed the suppression of MCF2L-AS1 on the CSC-like traits on NSCLC cells. Thus, this work identifies a novel MCF2L-AS1/miR-873-5p regulatory axis responsible for the CSC-like traits of NSCLC cells.Photothermal therapy usually requires a high power density to activate photothermal agent for effective treatment, which inevitably leads to damage to normal tissues and inflammation in tumor tissues. Herein, we rationally design a protein-binding strategy to build a molecular photothermal agent for photothermal ablation of tumor. The synthesized photothermal agent can covalently bind to the thiol groups on the intracellular proteins. The heat generated by the photothermal agent directly destroyed the bioactive proteins in the cells, effectively reducing the heat loss and the molecular leakage. Under a low power density of 0.2 W cm-2 , the temperature produced by the photothermal agent was sufficient to induce apoptosis. In vitro and in vivo experiments showed that the therapeutic effect of photothermal therapy can be efficiently improved with the protein-binding strategy.To study metalloenzymes in detail, we developed a new experimental setup allowing the controlled preparation of catalytic intermediates for characterization by various spectroscopic techniques. The in situ monitoring of redox transitions by infrared spectroscopy in enzyme lyophilizate, crystals, and solution during gas exchange in a wide temperature range can be accomplished as well. Two O2 -tolerant [NiFe]-hydrogenases were investigated as model systems. First, we utilized our platform to prepare highly concentrated hydrogenase lyophilizate in a paramagnetic state harboring a bridging hydride. This procedure proved beneficial for 57 Fe nuclear resonance vibrational spectroscopy and revealed, in combination with density functional theory calculations, the vibrational fingerprint of this catalytic intermediate. The same in situ IR setup, combined with resonance Raman spectroscopy, provided detailed insights into the redox chemistry of enzyme crystals, underlining the general necessity to complement X-ray crystallographic data with spectroscopic analyses.To explore the dynamics of biomolecules, tracing the kinetics of photo-induced chemical reactions via the triplet excited state (T1 ) of probe molecules offers a timescale that is about 106 times wider than via the singlet excited state (S1 ). Using cyclooctatetraene (COT) as a triplet energy acceptor and at the same time as a photostabilizer, the triplet-triplet energy transfer (TTET) kinetics governed by oligonuc
