Transcriptome analysis of tree peony under high temperature treatment and functional verification of PsDREB2A gene.

Paeonia suffruticosa is a plant of Paeonia in Paeoniaceae. It is an important woody ornamental flower in the world. High temperature in summer hinders the growth of tree peony and reduces its ornamental quality, which restricts the cultivation and application of tree peony in Jiangnan area of China.

Mining Heat-Resistant Key Genes of Peony Based on Weighted Gene Co-Expression Network Analysis.

The RNA-Seq and gene expression data of mature leaves under high temperature stress of 'Hu Hong' were used to explore the key genes of heat tolerance of peony. The weighted gene co-expression network analysis (WGCNA) method was used to construct the network, and the main modules and core genes of co-expression were screened according to the results of gene expression and module function enrichment analysis. According to the correlation of gene expression, the network was divided into 19 modules.

Identification of Metabolism-Related Genes Influencing Prognosis of Multiple Myeloma Patients.

Multiple myeloma (MM) is the second most commonly diagnosed hematological malignancy. Understanding the basic mechanisms of the metabolism in MM may lead to new therapies that benefit patients. We collected the gene expression profile data of GSE39754 and performed differential analysis.

A novel silicone derivative of natural osalmid (DCZ0858) exerts anti-multiple myeloma activity by promoting cell apoptosis and inhibiting cell cycle and mTOR signaling.

Multiple myeloma (MM) is a malignant disease characterized by abnormal proliferation of clonal plasma cells. Based on the organic drug osalmid, the novel small molecule compound DCZ0858 was designed and synthesized for treating MM. DCZ0858 inhibited the proliferation and activity of MM cells and reduced colony formation.

A novel M phase blocker, DCZ3301 enhances the sensitivity of bortezomib in resistant multiple myeloma through DNA damage and mitotic catastrophe.

Background: DCZ3301, a novel aryl-guanidino compound previously reported by our group, exerts cytotoxic effects against multiple myeloma (MM), diffused large B cell lymphoma (DLBCL), and T-cell leukemia/lymphoma. However, the underlying mechanism of its action remains unknown.

Methods: We generated bortezomib (BTZ)-resistant cell lines, treated them with various concentrations of DCZ3301 over varying periods, and studied its effect on colony formation, cell proliferation, apoptosis, cell cycle, DNA synthesis, and DNA damage response.

Novel cyclophosphamide of natural products osalmide and pterostilbene induces cytotoxicity and cell cycle arrest in diffuse large B-cell lymphoma cells.

Diffuse large B-cell lymphoma (DLBCL) is the most common category and disease entity of non-Hodgkin lymphoma. Osalmide and pterostilbene are natural products with anticancer activities via different mechanism. In this study, using a new synthetic strategy for the two natural products, we obtained the compound DCZ0801, which was previously found to have anti-multiple myeloma activity.

Rafoxanide, an organohalogen drug, triggers apoptosis and cell cycle arrest in multiple myeloma by enhancing DNA damage responses and suppressing the p38 MAPK pathway.

Rafoxanide is used in veterinary medicine for the treatment of fascioliasis. We previously repositioned the drug as the inhibitor of B-Raf V600E, but its anti-tumor effect in human cancer has never been reported. In this study, we investigated the effects of rafoxanide in multiple myeloma (MM) in vitro and in vivo.

Targeting the PI3K/Akt/mTOR signaling pathway by pterostilbene attenuates mantle cell lymphoma progression.

Mantle cell lymphoma (MCL) is an aggressive and mostly incurable B-cell malignancy with frequent relapses after an initial response to standard chemotherapy. Therefore, novel therapies are urgently required to improve MCL clinical outcomes. In this study, MCL cell lines were treated with pterostilbene (PTE), a non-toxic natural phenolic compound primarily found in blueberries.

Dihydrocelastrol exerts potent antitumor activity in mantle cell lymphoma cells via dual inhibition of mTORC1 and mTORC2.

Mantle cell lymphoma (MCL) is a distinct and highly aggressive subtype of B-cell non-Hodgkin lymphoma. Dihydrocelastrol (DHCE) is a dihydro-analog of celastrol, which is isolated from the traditional Chinese medicinal plant Tripterygium wilfordii. The present study aimed to investigate the effects of DHCE treatment on MCL cells, and to determine the mechanism underlying its potent antitumor activity in vitro and in vivo using the Cell Counting kit-8 assay, clonogenic assay, apoptosis assay, cell cycle analysis, immunofluorescence staining, western blotting and tumor xenograft models.

PKC inhibition of sotrastaurin has antitumor activity in diffuse large B-cell lymphoma via regulating the expression of MCT-1.

MCT-1 (multiple copies in T-cell lymphoma-1), a novel oncogene, was originally identified in T-cell lymphoma. A recent study has demonstrated that MCT-1 is highly expressed in 85% of diffuse large B-cell lymphomas (DLBCL). PKC (protein kinase C) plays an essential role in signal transduction for multiple biologically active substances for activating cellular functions and proliferation.

Dual inhibition of mTORC1/2 by DCZ0358 induces cytotoxicity in multiple myeloma and overcomes the protective effect of the bone marrow microenvironment.

Interaction of multiple myeloma (MM) cells with the bone marrow (BM) microenvironment promotes the proliferation, survival and chemoresistance of MM. The mTOR pathway plays a key role in these undesirable BM microenvironment-mediated events. We synthesized a novel alkaloid compound, DCZ0358, that effectively inhibits mTOR signaling via dual mTORC1/2 inhibition and exhibits potent anti-MM activity in cultured and primary MM cells, as well as a MM xenograft model but has little effect on normal cells.
