Abstract
BACKGROUND Acute-on-chronic liver failure (ACLF) constitutes a prevalent manifestation of liver failure within clinical settings. This condition manifests swiftly and is characterized by an exceedingly elevated fatality rate. OBJECTIVE While numerous investigations have delved into the role of RNA methylation in ferroptosis, the impact of such methylation on ACLF-associated ferroptosis remains notably underexplored. This study aimed to elucidate the molecular mechanism underlying the efficacy of Niujiao Dihuang Jiedu decoction (NDD) in mitigating ferroptosis in ACLF, with a specific focus on RNA 5-methylcytosine (m5C) methylation. MATERIALS AND METHODS An ACLF rat model was established alongside an erastin-induced ferroptosis model in LO2 cells. Both in vitro and in vivo experiments were conducted to substantiate NDD's influence on ferroptosis. The modifying influence of methylase NOL1/NOP2/sun domain (NSUN5) upon SLC7A11, a key ferroptosis-associated gene, was probed through dot blot, immunofluorescence co-localization, and RNA binding protein immunoprecipitation (RIP) experiments. RESULTS Serological and hepatic histopathological findings indicated NDD's discernible therapeutic impact on ACLF. Furthermore, ferroptosis phenotype experiments revealed NDD's proficiency in effectively impeding the occurrence and development of ferroptosis. Dot blot assays demonstrated a reduction in the overall RNA m5C levels during cellular ferroptosis. Furthermore, through immunofluorescence co-localization and RIP techniques, we found that the propensity of methylase NSUN5 to associate with SLC7A11 mRNA, thereby enhancing its protein translation and conferring resistance against ferroptosis. CONCLUSION RNA methylation is involved in the process of ACLF-associated ferroptosis, and NDD can inhibit ACLF-associated ferroptosis by fostering SLC7A11 m5C methylation.

SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2023; 299:122876.

Abstract
The derivatives of sulfur dioxide (HSO3-) formed in the biological environment play a vital role in the circulation system. Excessive SO2 derivatives will cause serious damage to the living system. Herein, a two-photon phosphorescent probe based on Ir(III) complex (named as Ir-CN) was designed and synthesized. Ir-CN is extremely selective and sensitive to SO2 derivatives with significant phosphorescent enhancement and increased phosphorescent lifetime. The detection limit of Ir-CN for SO2 derivatives reaches 0.17 μM. More importantly, Ir-CN preferentially accumulates in mitochondria, so bisulfite derivatives can be detected at subcellular level, which enriching the application of metal complex probe in biological detection. In addition, both single-photon and two-photon images can clearly show that Ir-CN is targeted to mitochondria. Benefits from its good biocompatibility, Ir-CN may be used as a reliable tool to detect SO2 derivatives in mitochondrion of living cells.

Abstract
Cancer is threatening the survival of human beings all over the world. Phototherapy (including photothermal therapy (PTT) and photodynamic therapy (PDT)) and bioimaging are important tools for imaging-mediated cancer theranostics. Diketopyrrolopyrrole (DPP) dyes have received more attention due to their high thermal and photochemical stability, efficient reactive oxygen species (ROS) generation and thermal effects, easy functionalization, and tunable photophysical properties. In this review, we outline the latest achievements of DPP derivatives in cancer therapy and imaging over the past three years. DPP-based conjugated polymers and small molecules for detection, bioimaging, PTT, photoacoustic imaging (PAI)-guided PTT, and PDT/PTT combination therapy are summarized. Their design principles and chemical structures are highlighted. The outlook, challenges, and future opportunities for the development of DPP derivatives are also presented, which will give a future perspective for cancer treatment.

Abstract
Sulfite is widely used as an antioxidant additive and preservative in food and beverages. Abnormal levels of sulfite in the body is related to a variety of diseases. There are strict rules for sulfite intake. Therefore, to monitor the sulfite level in physiological and pathological events, there is in urgent need to develop a rapid, accurate, sensitive, and non-invasive approach, which can also be of great significance for the improvement of the corresponding clinical diagnosis. With the development of fluorescent probes, many advantages of fluorescent probes for sulfite detection, such as real time imaging, simple operation, economy, fast response, non-invasive, and so on, have been gradually highlighted. In this review, we enumerated almost all the sulfite fluorescent probes over nearly a decade and summarized their respective characteristics, in order to provide a unified platform for their standardized evaluation. Meanwhile, we tried to systematically review the research progress of sulfite small-molecule fluorescent probes. Logically, we focused on the structures, reaction mechanisms, and applications of sulfite fluorescent probes. We hope that this review will be helpful for the investigators who are interested in sulfite-associated biological procedures.

Abstract
A turn-on fluorescence probe PQP-1 with a pyrroloquinoline skeleton has been designed and synthesized. Probe PQP-1 showed high sensitivity to HSO3-, low detection limit (16.83 nM), and a wide linear range (50-3000 μM). More importantly, probe PQP-1 could distinguish between HSO3- and SO32-. Furthermore, cell imaging experiments of HSO3- in HeLa cells revealed that probe PQP-1 had potential application value in biological systems.
