Firstly, the reference drug Palbociclib was identified from the available literature as a potential candidate against target CDK4. In the present study, the Collection of Open Natural Products (COCONUT) database was accessed for determining potential CDK4 inhibitors using computational approaches based on the Tanimoto algorithm for similarity with the target drug, i.e., Palbociclib. The potential candidates were analyzed using SWISSADME, and the best candidates were filtered based on Lipinski's Rule of 5, Brenk, blood-brain barrier permeability, and Pains parameter. Further, the molecular docking protocol was accessed for the filtered compounds to anticipate the CDK4-ligand binding score, which was validated by the fastDRH web-based server. Based on the best docking score so obtained, the best four natural compounds were chosen for further molecular dynamic simulation to assess their stability with CDK4.

The CIBERSORT algorithm is widely employed to determine the proportion of immune cells (ICs) in diseased tissues, while the Sonic Hedgehog (Shh) signaling pathway, as an imperative regulatory factor, has also attracted attention in the pathology of RA-ILD. This work was to explore the mechanisms of RA-ILD immune infiltration and synovial tissue (ST) Shh expression based on the CIBERSORT algorithm. The differential genes of RA-ILD were subjected to pathway enrichment analysis using R language. The content and proportion of 22 types of ICs in RA-ILD lung tissues were analyzed using machine learning-based CIBERSORT algorithm. Meanwhile, immunoblotting was employed to detect and analyze the expression of Shh, Smoothened (Smo), and bone morphogenetic proteins (BMPs) proteins in ST samples from RA-ILD and Ctrl groups (RA patients without ILD). The hub target genes in the protein network associated with RA-ILD include BSG, CCL2, CTLA4, FGFBP1, GLI1, HHIP, HLA-DRB1, IFNAR1, IL17A, IL23A, IL-6, INPP4A, LILRB1, MUC5B, PADI4, PPM1A, PTCH1, PTPN22, RSPO4, Shh, SMO, STAT4, SUFU, TAOK2, TIMP2, and TWSG1, which are involved in multiple pathways, such as B cell regulation, transcription factors of the Shh pathway, and ST immune tolerance-related pathways. In the immunological analysis of RA-ILD using the CIBERSORT algorithm, HLA (r = - 0.26), PTPN22 (r = - 0.36), STAT4 (r = - 0.18), IL-6 (r = - 0.17), CTLA4 (r = - 0.27), and PADI4 (r = - 0.21) were all found to exhibit negative correlations with CD4+T cells (P < 0.05). Monocytes were found to be more abundant in RA-ILD patients' serum versus the Ctrl group. Shh, Smo, and BMP expressions were drastically lower in the RA-ILD group versus Ctrl group (P < 0.05). Significant immune cell infiltration was observed in the lung tissues of RA-ILD patients. Further analysis utilizing the CIBERSORT algorithm revealed alterations in the proportions of different IC subtypes, indicating their association with disease severity and prognosis. Moreover, there was a significant decrease in the expression levels of Shh, Smo, and BMP.
