Abstract
Radiation molecularly transforms naturally occurring products by inducing the methoxylation, hydroxylation, and alkylation of parent compounds, thereby affecting the anti-inflammatory capacities of those compounds. Minaprine (1) modified by ionizing radiation generated the novel hydroxymethylation hydropyridazine (2), and its chemical structure was determined based on NMR and HRESIMS spectra. Compared to the original minaprine, the novel generated product showed a highly enhanced anti-inflammatory capacity inhibited nitric oxide (NO) and prostaglandin E2 (PGE2) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 and DH82 macrophage cells. In addition, minaprinol (2) effectively inhibited cyclooxygenase-2 (COX-2) and inducible NO synthase (iNOS) at the protein level and pro-inflammatory cytokine (tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and IL-10) production in macrophages.

Tantawy MA, Shalby AB, Barnawi IO, Kattan SW, Abd-Rabou AA, Elmegeed GA. Anti-cancer activity, and molecular docking of novel hybrid heterocyclic steroids revealed promising anti-hepatocellular carcinoma agent: Implication of cyclin dependent kinase-2 pathway. Steroids 2023; 193:109187. [PMID: 36736802 DOI: 10.1016/j.steroids.2023.109187] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Revised: 01/24/2023] [Accepted: 01/30/2023] [Indexed: 02/04/2023]
Abstract
To identify new steroidal agents with potential biological activities, we synthesized hybrid steroids containing thiazole, pyrazole, isoxazole, thiophene or phthalazine moiety. Epi-androsterone 1 reacted with phenylthiosemicarbazide to afford the corresponding androstane-4-phenyl-3-thiosemicarbazone derivative 2. The latter product was used in the synthesis of a series of annulated steroid derivatives. Also, Epi-androsterone 1 reacted with the thienopyridazine derivative 16 to afford the thieno[3,4-d]pyridazino-N-ylidenoandrostane derivative 17. Compound 17 reacted readily with electron-poor olefins to yield the corresponding phthalazine steroid derivatives. Detailed experimental and spectroscopic evidences for the structures of the newly synthesized compounds are explained. Compounds 3, 7, 8a, 12a, 14, 17 and 21a, were investigated individually as anticancer agents on different panel of human malignant cell lines. Moreover, a computer modelling investigation was performed to speculate the macromolecular targets for the most promising candidate. The results revealed a concentration-dependent reduction in the number of viable cells in all cancer cell lines. Most notably, compound 7 was the most effective compound against all tested cancer cell lines, especially against HepG2 cell line; therefore, the mode of action of this compound against HCC was investigated. Compound 7 was able to induce cell cycle arrest, and DNA fragmentation in HepG2 cells. Moreover, compound 7 induced apoptosis via upregulating the expression of caspase-3, -8, -9, P53, Bax and inhibiting the expression of BCL2, and CDK2 genes. Our results highlighted compound 7 as a promising anti-hepatocellular carcinoma agent, with theoretical, and practical potential binding affinity with CDK2; therefore, more investigations are required to elucidate its chemotherapeutic value as anti-HCC agent.

Abstract
The use of glucocorticoids is very varied in the context of cancer patients and includes the treatment of symptoms related to cancer, but also the management of the most common side effects of antitumor treatments or adverse events related to the immune system. There is a quantity of experimental evidence demonstrating that cancer cells are immunogenic. However, the effective activation of anticancer T cell responses closely depends on an efficient antigen presentation carried out by professional antigen-presenting cells such as dendritic cells (DCs). The classic strategies to improve the medical management of inflammation are aimed at exacerbating the host's immune response. Although successful in treating a number of diseases, these drugs have limited efficacy and variable responses can lead to unpredictable results. The ideal therapy should reduce inflammation without inducing immunosuppression and remains a challenge for healthcare personnel.

Big Data Analysis and Application of Liver Cancer Gene Sequence Based on Second-Generation Sequencing Technology. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:4004130.

Abstract
In big data analysis with the rapid improvement of computer storage capacity and the rapid development of complex algorithms, the exponential growth of massive data has also made science and technology progress with each passing day. Based on omics data such as mRNA data, microRNA data, or DNA methylation data, this study uses traditional clustering methods such as kmeans, K-nearest neighbors, hierarchical clustering, affinity propagation, and nonnegative matrix decomposition to classify samples into categories, obtained: (1) The assumption that the attributes are independent of each other reduces the classification effect of the algorithm to a certain extent. According to the idea of multilevel grid, there is a one-to-one mapping from high-dimensional space to one-dimensional. The complexity is greatly simplified by encoding the one-dimensional grid of the hierarchical grid. The logic of the algorithm is relatively simple, and it also has a very stable classification efficiency. (2) Convert the two-dimensional representation of the data into the one-dimensional representation of the binary, realize the dimensionality reduction processing of the data, and improve the organization and storage efficiency of the data. The grid coding expresses the spatial position of the data, maintains the original organization method of the data, and does not make the abstract expression of the data object. (3) The data processing of nondiscrete and missing values provides a new opportunity for the identification of protein targets of small molecule therapy and obtains a better classification effect. (4) The comparison of the three models shows that Naive Bayes is the optimal model. Each iteration is composed of alternately expected steps and maximal steps and then identified and quantified by MS.

Prednisolone and mesenchymal stem cell preloading protect liver cell migration and mitigate extracellular matrix modification in transplanted decellularized rat liver. Stem Cell Res Ther 2022; 13:36. [PMID: 35090559 PMCID: PMC8800282 DOI: 10.1186/s13287-022-02711-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Accepted: 01/10/2022] [Indexed: 02/07/2023] Open
Abstract
INTRODUCTION Regenerative medicine provides promising approaches for treating chronic liver diseases. Previous studies indicate that decellularized liver architecture is damaged by invading non-hepatic inflammatory cells. This study aimed to use anti-inflammatory and regenerative potency of bone marrow-derived mesenchymal stem cells (BM-MSC) and prednisolone for reducing fibrosis and balancing inflammatory cell migration into the decellularized liver scaffold. MATERIAL AND METHOD The liver was decellularized by perfusing Sodium Lauryl Ether Sulfate (SLES), and nuclei depletion and extracellular matrix (ECM) retention were confirmed by DNA quantification, histochemical, and immunohistochemical assessments. Scaffolds were loaded with BM-MSCs, prednisolone, or a combination of both, implanted at the anatomical place in the rat partial hepatectomized and followed up for 2 and 4 weeks. RESULTS Labeled-MSCs were traced in the transplanted scaffolds; however, they did not migrate into the intact liver. Immunohistochemistry showed that the hepatoblasts, cholangiocytes, stellate, and oval cells invaded into all the scaffolds. Bile ducts were more abundant in the border of the scaffolds and intact liver. Stereological assessments showed a significant reduction in the number of lymphocytes and neutrophils in prednisolone-loaded scaffolds. The regeneration process and angiogenesis were significantly higher in the group treated with cell/prednisolone-loaded bioscaffolds. Collagen fibers were significantly reduced in the scaffolds pre-treated with cell/prednisolone, prednisolone, or BM-MSCs, compared to the control group. CONCLUSION Loading prednisolone into the scaffolds can be a worthy approach to restrict inflammation after transplantation. Although pre-loading of the scaffolds with a combination of cells/prednisolone could not alleviate inflammation, it played an important role in regeneration and angiogenesis.
