Since the hTAS2R38 protein lacked a crystallographic structure, it was modelled using contact-guided iterative threading assembly refinement, its residues were mutated and refined, and the binding pocket area and volume were assessed using CASTp. Bitter thiourea molecules were docked using the ligand extra precision module and the receptor–ligand complex was manually positioned in a fully hydrated, equilibrated 1-palmitoyl-2-oleoylphosphatidylcholine bilayer using the CHARMM GUI membrane constructor, a 100 ns simulation was carried out using the Desmond program. Analysis revealed that the PROP binds to the allosteric hydrophobic pocket of hTAS2R38 and forms a hydrogen bond with ASN190. The native structure (hTAS2R38_PAV) has a higher glide energy (−24.164 kcal/mol) and docking score (−7.212 kcal/mol) than mutants, corroborating our taste preference study. In contrast, PTC lacks hydrogen bonds in the binding pocket but exhibits pi–pi stacking interactions with the native structure. Structures with mutations at the 49th or 296th position showed the largest root mean square deviations and fluctuations. A triple mutation increases surface area and volume, making the 262nd position critical to the binding pocket.

Physicochemical properties, secondary and tertiary structures, and phylogenetic trees, along with protein sequence alignments of receptor tyrosine kinases (RTKs) and ALK fused partner genes, were examined using the resources provided by the National Center for Biotechnology Information (NCBI) and the Catalogue of Somatic Mutations in Cancer (COSMIC). Sequence alignments were performed to identify common sequences between partner genes and search for common breakpoints within the COSMIC database. ALK is a large, unstable, acidic protein with similarly conservation among RTKs. ALK fusion partners are mostly acidic, unstable proteins, mostly consisting of α-helices and random coil. However, <i>EML4</i> and <i>NPM1</i> are the most frequently occurring partner genes and have their own unique structural characteristics. By functional domain analysis, we found that the functions of the first half of the <i>ALK</i> partner gene (the part fused to ALK) are mostly focused on signaling. ALK is identified as a large hydrophilic protein，exhibits a higher proportion of random coils. Compared to other RTKs, ALK has fewer structural domains (PTKC_ALK_LTK domain). Pairwise comparison with fusion partner genes revealed a conserved sequence predicted to have structural stability and act as a common binding site for nucleases. Exon 20 of <i>ALK</i> is a fusion frequent site according to COSMIC database analysis. The structural instability of ALK and partner genes, coupled with the inherent variability of breakpoint sequences, leads to the formation of potent kinase-activated oncogenes, which play a critical role in tumorigenesis.

Subsequent treatment with Pemetrexed resulted in a significant reduction in liver metastases. Protein mass spectrometry sequencing and immunohistochemical analysis collectively indicated that the PI3K/mTOR pathway mediates the mechanism through which these gene mutations confer primary drug resistance. Evidence demonstrates that the co-occurrence of EGFR and ARID1A mutations diminishes the efficacy of EGFR tyrosine kinase inhibitors (EGFR TKIs). Consequently, it is hypothesized that mutations in NTRK1 and ZRSR2, which are implicated in the PI3K/mTOR pathway, contribute to the primary resistance observed with Osimertinib treatment. In this case, the illness was effectively managed through prompt adjustments to the treatment regimen and the rapid administration of chemotherapy drugs.

Zinc finger protein 169 (ZNF169) holds significant importance as a transcription factor, yet its precise function in HCC remains to be elucidated. This study aims to examine the clinical importance, biological functions, and molecular pathways associated with ZNF169 in the development of HCC. The study employed lentiviral transduction for ZNF169 overexpression and the use of small interfering RNAs (siRNAs) to suppress its expression. ZNF169 was upregulated in HCC tissues and cell lines. Additionally, HCC patients exhibiting elevated ZNF169 levels experienced reduced overall survival, shorter disease-free survival, and diminished progression-free survival. Silencing of ZNF169 inhibited cell proliferation, migration, and cell cycle progression. Whereas ectopic expression of ZNF169 promoted HCC progression in vivo and ex vivo. Subsequently, Pearson analysis results showed that cyclin-dependent kinase 19 (CDK19) was positively correlated with ZNF169 levels in HCC using TCGA dataset. Luciferase assay findings indicated a potential interaction between ZNF169 and CDK19 promoter. Additionally, our data showed that CDK19 expression levels were elevated in HCC tissues, and patients with higher CDK19 expression faced a poorer prognosis. Furthermore, recovery experiments demonstrated that CDK19 could reverse the impact of ZNF169 on HCC cell amplification.

Herein, integrated analysis of bulk and single-cell RNA-seq profiling was conducted to characterize senescence-based heterogeneity in pancreatic cancer. Publicly available bulk and single-cell RNA sequencing from pancreatic cancer patients were gathered from TCGA-PAAD, PACA-AU, PACA-CA, and GSE154778 datasets. The activity of three senescence-related pathways (cell cycle, DNA repair, and inflammation) was scored utilizing ssGSEA algorithm. A series of functional verifications of crucial genes were accomplished in patient tissue and pancreatic cancer cells. Based upon them, unsupervised clustering analysis was executed to classify pancreatic cancer samples into distinct senescence-based clusters at the bulk and single-cell levels. For single-cell transcriptome profiling, cell clustering and annotation were implemented, and malignant cells were recognized utilizing infercnv algorithm. Two senescence-based clusters were established and highly reproducible at the bulk level, with the heterogeneity in prognosis, clinicopathological features, genomic CNVs, oncogenic pathway activity, immune microenvironment and immune checkpoints. Senescence-relevant gene CHGA, UBE2C and MCM10 were proved to correlate with the migration and prognosis of pancreatic cancer. At the single-cell level, seven cell types were annotated, comprising ductal cells 1, ductal cells 2, fibroblasts, macrophages, T cells, stellate cells, and endothelial cells. The senescence-based classification was also proven at the single-cell level. Ductal cells were classified as malignant cells and non-malignant cells. In the tumor microenvironment of malignant cells, hypoxia and angiogenesis affected senescent phenotype. The heterogeneity in senescence was also observed between and within cell types.

Using weighted gene co-expression network analysis (WGCNA), we identified 83 hub genes by integrating gene expression profiles with clinical pathological grades. A machine learning-based integrative approach further pinpointed 12 prognostic genes, among which CDKN3 exhibited the highest hazard ratio and the most adverse impact on overall survival (OS) in BC patients. Additionally, CDKN3 was identified as an independent prognostic factor for OS prediction. CDKN3 overexpression was confirmed in BC patients and validated at both mRNA and protein levels in BC cells. Knockdown of CDKN3 significantly inhibited the migration and proliferation of BC cells. Cell cycle pathway analysis revealed significant enrichment in G2M-associated pathways in BC patients, with multi-transcriptomic data indicating a close association between enhanced G2M cell cycle activity and CDKN3 upregulation in basal cancer subtypes. Pseudotime analysis further suggested CDKN3 upregulation during the G2M phase at the terminal trajectory of basal cancer subtypes, implying that CDKN3 may drive BC cell progression by promoting G2M cell cycle activity. Mechanistically, CDKN3 knockdown induced G2M cell cycle arrest in TNBC cells by downregulating CCNB2.
