Abstract
Cysteine (Cys) is one of the most basic mercaptans in the human body. As an important endogenous small molecule mercaptan, Cys plays a vital role in various physiological processes and can participate in maintaining redox balance to ensure homeostasis. Abnormal Cys levels can lead to a variety of diseases. However, the detection of cysteine may be interfered with by other small molecule biothiols. Therefore, the design of fluorescent probes based on the structural characteristics and reactivity of cysteine has become the focus of current research. In this paper, a fluorescent probe (3-(2H-benzo[d][1,2,3]triazol-2-yl)-2-oxo-2H-benzo[g]chromen-8-yl acrylate, BTAB) for Cys detection was synthesized with acrylic ester as the reaction site. Under the conditions of gradual optimization, BTAB can achieve selectivity and anti-interference ability for Cys detection. The linear range of Cys was 0.3-10 μM, and the detection limit was 0.154 μM. Finally, this probe was applied to detect the Cys content in bovine serum samples with satisfactory results.

Abstract
Diffuse Large B-cell Lymphoma (DLBCL), with its intrinsic genetic and epigenetic heterogeneity, exhibits significantly variable clinical outcomes among patients treated with the current standard regimen. Disulfidptosis, a novel form of regulatory cell death triggered by disulfide stress, is characterized by the collapse of cytoskeleton proteins and F-actin due to intracellular accumulation of disulfides. We investigated the expression variations of disulfidptosis-related genes (DRGs) in DLBCL using two publicly available gene expression datasets. The initial analysis of DRGs in DLBCL (GSE12453) revealed differences in gene expression patterns between various normal B cells and DLBCL. Subsequent analysis (GSE31312) identified DRGs strongly associated with prognostic outcomes, revealing eight characteristic DRGs (CAPZB, DSTN, GYS1, IQGAP1, MYH9, NDUFA11, NDUFS1, OXSM). Based on these DRGs, DLBCL patients were stratified into three groups, indicating that (1) DRGs can predict prognosis, and (2) DRGs can help identify novel therapeutic candidates. This study underscores the significant role of DRGs in various biological processes within DLBCL. Assessing the risk scores of individual DRGs allows for more precise stratification of prognosis and treatment strategies for DLBCL patients, thereby enhancing the effectiveness of clinical practice.

Abstract
As one of the most fundamental thiol compounds in the human body, cysteine (Cys) is involved in maintaining redox balance. Abnormal Cys levels can lead to various diseases. In this work, we successfully synthesized a fluorescent probe (CTBA) that can specifically detect Cys using acrylate as the reaction site, and CTBA has met the selectivity and anti-interference for Cys detection under optimized conditions. The linear range for Cys detection is between 0.05 and 100 μM and the detection limit is 0.0381 μM. Finally, this probe is used to detect the Cys content in three bovine serum samples and the test results are satisfactory.

Abstract
Peroxiredoxins (Prx), thiol-dependent peroxidases, were first identified as H2O2 detoxifiers, and more recently as H2O2 sensors, intermediates in redox-signaling pathways, metabolism modulators, and chaperones. The multifaceted nature of Prx is not only dependent on their peroxidase activity but also strongly associated with specific protein-protein interactions that are being identified, and where the Prx oligomerization dynamics plays a role. Their oxidation by a peroxide substrate forms a sulfenic acid that opens a route to channel the redox signal to diverse protein targets. Recent research underscores the importance of different Prx isoforms in the cellular processes behind disease development with potential therapeutic applications.

Abstract
HMGB1 is a dual-function protein that acts as a chromatin-binding protein and as a danger-associated molecular pattern (DAMP) when released from activated immune cells or injured tissue. In much of the HMGB1 literature, immunomodulatory effects of extracellular HMGB1 are proposed to depend on its oxidation state. However, many of the foundational studies for this model have been retracted or flagged with expressions of concern. The literature on HMGB1 oxidation reveals a diversity of redox proteoforms of HMGB1 that are inconsistent with current models of redox modulation regulating HMGB1 secretion. A recent study of acetaminophen toxicity has identified previously unrecognized HMGB1 oxidized proteoforms. HMGB1 undergoes oxidative modifications that could serve as pathology-specific biomarkers and drug targets.
