J Pineal Res 2024; 76:e12918. [PMID: 37814536 DOI: 10.1111/jpi.12918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 08/30/2023] [Accepted: 09/12/2023] [Indexed: 10/11/2023]
Abstract
Endometrial cancer (EC) is a reproductive system disease that occurs in perimenopausal and postmenopausal women. However, its etiology is unclear. Melatonin (MT) has been identified as a therapeutic agent for EC; however, its exact mechanism remains unclear. In the present study, we determined that GATA-binding protein 2 (GATA2) is expressed at low levels in EC and regulated by MT. MT upregulates the expression of GATA2 through MT receptor 1A (MTNR1A), whereas GATA2 can promote the expression of MTNR1A by binding to its promoter region. In addition, in vivo and in vitro experiments showed that MT inhibited the proliferation and metastasis of EC cells by upregulating GATA2 expression. The protein kinase B (AKT) pathway was also affected. In conclusion, these findings suggest that MT and GATA2 play significant roles in EC development.

Aktar A, Heit B. Role of the pioneer transcription factor GATA2 in health and disease. J Mol Med (Berl) 2023; 101:1191-1208.

Abstract
The transcription factor GATA2 is involved in human diseases ranging from hematopoietic disorders, to cancer, to infectious diseases. GATA2 is one of six GATA-family transcription factors that act as pioneering transcription factors which facilitate the opening of heterochromatin and the subsequent binding of other transcription factors to induce gene expression from previously inaccessible regions of the genome. Although GATA2 is essential for hematopoiesis and lymphangiogenesis, it is also expressed in other tissues such as the lung, prostate gland, gastrointestinal tract, central nervous system, placenta, fetal liver, and fetal heart. Gene or transcriptional abnormalities of GATA2 causes or predisposes patients to several diseases including the hematological cancers acute myeloid leukemia and acute lymphoblastic leukemia, the primary immunodeficiency MonoMAC syndrome, and to cancers of the lung, prostate, uterus, kidney, breast, gastric tract, and ovaries. Recent data has also linked GATA2 expression and mutations to responses to infectious diseases including SARS-CoV-2 and Pneumocystis carinii pneumonia, and to inflammatory disorders such as atherosclerosis. In this article we review the role of GATA2 in the etiology and progression of these various diseases.

Abstract
COL1A1 encodes the type I collagen α1 chain, which shows the highest abundance among members of the collagen family and is widely expressed in different mammalian cells and tissues. However, its molecular characteristics are not completely elucidated. In this study, the molecular profiles of COL1A1 and characteristics of the COL1A1 protein were investigated using a promoter activity assay and multiple bioinformatics tools. The results showed that the 5' flanking region of porcine COL1A1 contained two CpG islands, five core promoter sequences, and twenty-six transcription factor-binding sites. In the luciferase assay, the upstream 294 bp region of the initiation codon of COL1A1 showed the highest activity, confirming that this section is the core region of the porcine COL1A1 promoter. Bioinformatic analysis revealed that COL1A1 is a negatively charged, hydrophilic secreted protein. It does not contain a transmembrane domain and is highly conserved in humans, mice, sheep, and pigs. Protein interaction analysis demonstrated that the interaction coefficient of COL1A1 with COL1A2, COL3A1, ITGB1, and ITGA2 was greater than 0.9, suggesting that this protein plays a crucial role in collagen structure formation and cell adhesion. These results provide a theoretical basis for further investigation of the functions of porcine COL1A1.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease that results in the destruction of tissue by attacks on the patient by his or her own immune system. Current treatment strategies are not sufficient to overcome RA. In the present study, various transcriptomic data from synovial fluids, synovial fluid-derived macrophages, and blood samples from patients with RA were analysed using bioinformatics approaches to identify tissue-specific repurposing drug candidates for RA. Differentially expressed genes (DEGs) were identified by integrating datasets for each tissue and comparing diseased to healthy samples. Tissue-specific protein-protein interaction (PPI) networks were generated and topologically prominent proteins were selected. Transcription-regulating biomolecules for each tissue type were determined from protein-DNA interaction data. Common DEGs and reporter biomolecules were used to identify drug candidates for repurposing using the hypergeometric test. As a result of bioinformatic analyses, 19 drugs were identified as repurposing candidates for RA, and text mining analyses supported our findings. We hypothesize that the FDA-approved drugs momelotinib, ibrutinib, and sodium butyrate may be promising candidates for RA. In addition, CHEMBL306380, Compound 19a (CHEMBL3116050), ME-344, XL-019, TG100801, JNJ-26483327, and NV-128 were identified as novel repurposing candidates for the treatment of RA. Preclinical and further validation of these drugs may provide new treatment options for RA.

J Colloid Interface Sci 2021; 610:313-320. [PMID: 34923269 DOI: 10.1016/j.jcis.2021.11.190] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 11/29/2021] [Accepted: 11/29/2021] [Indexed: 12/23/2022]
Abstract
Dense tumor stroma is the physiological barrier in drug delivery that prevents anticancer drugs from entering the tumor, thereby seriously limiting the drugs' therapeutic effect. In this study, a Janus nanoplatform consisting of periodic mesoporous organosilica-coated platinum nanoplatforms (JPMO-Pt) and anti-stroma drug halofuginone (HF) (denoted as JPMO-Pt-HF), was developed to deplete the tumor stroma and synergistically treat breast cancer in BALB/c mice. The prepared JPMO-Pt had a uniform size of 245 nm, a good dispersion, an excellent in vitro and in vivo biocompatibility, and a high loading capacity for HF (up to 50 μg/mg). The antitumor experiments showed that the survival rate of 4 T1 cells exhibited an obvious downward trend when the cells were incubated with the JPMO-Pt-HF and irradiated with 808 nm laser. Moreover, the cell survival rate was only about 10% at 48 h when the HF concentration was 2.0 μg/mL. Notably, JPMO-Pt-HF under irradiation had an excellent synergistic therapeutic effect on tumor cells. In vivo antitumor experiment further showed that the JPMO-Pt-HF, in combination with laser irradiation, could minimize tumor growth, showing significantly better effects than those observed for the case of monotherapy involving photothermal therapy (PTT) (152 vs. 670 mm3, p < 0.0001) and HF (152 vs. 419 mm3, p = 0.0208). In addition, immunohistochemistry of tumor tissues indicated that JPMO-Pt-HF obviously reduced the relative collagen and α-smooth muscle actin (α-SMA) area fraction. Taken together, this research designs a new platform that not only possesses the ability to degrade the tumor matrix but also combines PTT and chemotherapeutic effects, and holds promise for effective tumor treatment.
