Structural patterns for antitumor drugs, evidenced by means of a molecular interaction field (MIF) approach using grid independent descriptors (GRIND), resembled closely those of a previous independent pharmacological classification based on their antitumor mechanism of action. For topoisomerase II inhibitors, antimitotic agents and DNA antimetabolites, systematic structural patterns were evidenced by MIF and the structural features of "outliers" in these classes corresponded to peculiar pharmacological mechanisms of action supported by literature evidences. Alkylating agents and DNA/RNA antimetabolites, interacting with a large variety of targets by different molecular mechanisms, did not exhibit clustering in the structure-based MIF approach. Moreover MIFS were able to point out similarities between drugs which, in spite of apparent dramatic differences in chemical structure, exhibit the same pharmacological behaviour.

In this study, we explored the impact of different biomechanical loadings on lumbar spine motion segments, particularly concerning intervertebral disc degeneration (IVDD). We aimed to uncover the cellular milieu and mechanisms driving ossification in the nucleus pulposus (NP) during IVDD, a process whose underlying mechanisms have remained elusive. The study involved the examination of fresh NP tissue from the L3-S1 segment of five individuals, either with IVDD or healthy.

Chronic hepatitis B virus (HBV) infection is a major risk factor for liver fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). Despite advances in understanding HBV-related liver diseases, effective therapeutic strategies remain limited. Macrophage migration inhibitory factor (MIF) has been implicated in various inflammatory and fibrotic conditions, but its role in HBV-induced liver fibrosis has not been fully explored.

Clear cell renal cell carcinoma (ccRCC) is one of the most challenging neoplasms because of its phenotypic variability and intratumoral heterogeneity. Because of its variability, ccRCC is a good test bench for the application of new technological approaches to unveiling its intricacies. Multiplex immunofluorescence (mIF) is an emerging method that enables the simultaneous and detailed assessment of tumor and stromal cell subpopulations in a single tissue section.

Astragali Radix (AR) is one of the monarch drugs of Fangji Huangqi decoction and has the effects of inducing diuresis to alleviate edema, tonifying and strengthening the body. However, there is a paucity of research regarding the effective fraction and the underlying metabolic mechanism of AR on nephrotic syndrome (NS). This work aims to elucidate the potential mechanisms of AR treating NS, as well as to identify effective part and components.

Background: Understanding the stepwise progression of esophageal squamous cell carcinoma (ESCC) is crucial for developing customized strategies for early detection and optimal clinical management. Herein, we aimed to unravel the transcriptional and immunologic alterations occurring during malignant transformation and identify clinically significant biomarkers of ESCC.
Methods: Digital spatial profiling (DSP) was performed on 11 patients with early-stage ESCC (pT1) to explore the transcriptional alterations in epithelial, immune cell, and non-immune cell stromal compartments across regions of distinct histology, including normal tissues, low- and high-grade dysplasia, and cancerous tissues.
