Study of silver aerosol source term at different specific internal energy input from HE detonation devices.

Radioactive aerosols harmful to humans are often produced in nuclear accidents, and their source term characteristics (total volume and particle size distribution) and dispersion patterns have important implications for accident response and hazard assessment. However, experimental studies of radioactive aerosols cannot be directly conducted in open space due to the hazardous nature of radioactive aerosols. In this study, silver was used instead of plutonium to study the aerosol source term under different specific internal energy inputs (SIEI) to simulate a low order explosion in an accident.

Transcriptome profiling provides insights into the molecular mechanisms of maize kernel and silk development.

mutation and clinicopathological features of colorectal cancer: a systematic review and Meta-Analysis.

There is conflicting evidence regarding the association between mutations and clinicopathological features of colorectal cancer (CRC). We performed a comprehensive meta-analysis investigating the association between mutations and clinicopathological features in CRC, including subgroup analysis of mutations in exons 9 and 20, to elucidate the role of mutations in CRC. A detailed literature search was performed within the PubMed, Web of Science, and Embase databases, examining the associations between mutations and demographic characteristics, clinicopathologic parameters, and molecular features in patients with CRC.

A novel BRCA1 germline mutation promotes triple-negative breast cancer cells progression and enhances sensitivity to DNA damage agents.

Breast cancer is the most frequent malignancy and the second leading cause of cancer death in female worldwide. Compared with general population, patients with mutations in BRCA1 and BRCA2 genes confer approximately 10-fold increased risk of breast cancer. In this study, we conducted whole-exome sequencing to identify the disease-associated genes in a specific pedigree, in which at least eight individuals were diagnosed with cancers, including breast cancer, urothelial cancer, uterine cancer and colorectal cancer.

DAXX, as a Tumor Suppressor, Impacts DNA Damage Repair and Sensitizes BRCA-Proficient TNBC Cells to PARP Inhibitors.

Treatment options are limited for patients with triple negative breast cancer (TNBC). Understanding genes that participate in cancer progression and DNA damage response (DDR) may improve therapeutic strategies for TNBC. DAXX, a death domain-associated protein, has been reported to be critically involved in cancer progression and drug sensitivity in multiple cancer types.

Combined Androgen receptor blockade overcomes the resistance of breast cancer cells to palbociclib.

The dysregulation of cyclin D -Cyclin-dependent kinase 4/6 (CDK4/6)-Rb axis has been implicated in breast cancer progression and the selective CDK4/6 inhibitors have shown effective activity in advanced breast cancer, especially in tumors driven by the estrogen receptor (ER). However, resistance to these small molecular inhibitors has become an inevitable clinical issue after their initial use. Here, we investigated the potential mechanism of resistance by establishing a CDK4/6 inhibitor palbociclib-resistant breast cancer cell line (MCF-7pR).

Therapeutic landscape in mutational triple negative breast cancer.

Triple negative breast cancer (TNBC) is a heterogeneous disease with aggressive behavior and poor prognosis. Genomic sequencing has detected a distinctive mutational portrait of both the germline and somatic alterations in TNBC, which is staggeringly different from other breast cancer subtypes. The clinical utility of sequencing germline BRCA1/2 genes has been well established in TNBC.

Emerging therapeutic modalities of PARP inhibitors in breast cancer.

Inhibition of Poly (ADP-ribose) polymerase (PARP) has shown marked benefit for breast cancer with homologous recombination deficiency, whether driven by defects in BRCA1, BRCA2, or other pathway components. Since the initial approval of olaparib, a mostly investigated PARP inhibitor (PARPi), the clinical development of PARPi in breast cancer treatment has been a major emphasis. Researches in investigating platinum-PARPi combination use compared with platinum monotherapy demonstrated promising benefit in metastatic BRCA mutated breast cancer or TNBC, while no such superiority was observed in the neoadjuvant setting of TNBC.

An androgen receptor negatively induced long non-coding RNA ARNILA binding to miR-204 promotes the invasion and metastasis of triple-negative breast cancer.

Androgen receptor (AR) is emerging as a novel prognostic biomarker in triple-negative breast cancer (TNBC), but the underlying mechanisms remain unknown. As accumulating evidence has shown that long non-coding RNAs (lncRNAs) regulate important cancer hallmarks, we hypothesised that AR-regulated lncRNAs might play roles in TNBC progression. Here, we performed experiments with or without DHT treatment in three TNBC cell lines, and we identified an AR negatively induced lncRNA (ARNILA), which correlated with poor progression-free survival (PFS) in TNBC patients and promoted epithelial-mesenchymal transition (EMT), invasion and metastasis in vitro and in vivo.

Androgen blockade based clinical trials landscape in triple negative breast cancer.

Androgen receptor (AR) targeted treatment has shown promising preliminary results in triple negative breast cancer (TNBC). Identification of AR-associated signaling pathways is of great significance for in-depth understanding of their roles in pathogenesis of TNBC. To meet this objective, preclinical and clinical studies were conducted to clarify the biological interactions of AR signaling and combination strategies based on AR-targeted therapy.

LAL test and RPT for endotoxin detection of CPT-11/DSPE-mPEG nanoformulation: What if traditional methods are not applicable?

Endotoxin detection is an important step in drug characterization. Herein we found that a chemotherapeutic drug nanoformulation composed of irinotecan hydrochloride (CPT-11) and an amphiphilic molecule DSPE-mPEG can interfere with the limulus amebocyte lysate assay (LAL). Furthermore, the rabbit pyrogen test (RPT) results indicated that at a relatively high dosage, the drug irinotecan hydrochloride can induce a hypothermia effect which may render the RPT results ambiguous in determination of the safety of the drug formulation.

Combined Inhibition of ATR and WEE1 as a Novel Therapeutic Strategy in Triple-Negative Breast Cancer.

Triple negative breast cancer (TNBC) is a highly aggressive subtype of breast cancer that poses a clinical challenge. Thus, new therapy strategies are urgently needed. The selective WEE1 inhibitor, AZD1775, has shown strong anti-proliferative effects on a variety of tumors.
