Previous studies have established the in vivo bioavailability and efficacious dosages of phenylbutyl isoselenocyanate (ISC-4), a selenium-substituted isothiocyanate, against mouse xenograft models of human melanoma and colorectal cancer. To explore its potential attributes against prostate cancer, we treated human LNCaP prostate cancer cells with ISC-4 and examined their apoptosis responses, and interrogated the signaling mechanisms through pharmacological and siRNA knockdown approaches. Our results show that ISC-4 was more potent at inducing apoptosis than its sulfur analog phenylbutyl isothiocyanate (PBITC) without suppressing protein kinase AKT Ser473 phosphorylation...

We reported two Au clusters with precisely controlled molecular size (Au5Peptide3 and Au22Peptide10) showing different anti-tumor effects. In vitro, both Au5Peptide3 and Au22Peptide10 were well taken up by human nasopharyngeal cancer cells (CNE1 cells). However, only Au5Peptide3 significantly induced CNE1 cell apoptosis. Further studies showed that CNE1 cells took up Au5Peptide3 (1.98*10-15 mol/cell) and 9% of them entered mitochondria (0.186*10-15 mol/cell). As a comparison, the uptake of Au22Peptide10 was only half the amount of Au5Peptide3 (1...

Selenium (Se) has been recognized as an essential element. Animals and humans absorb and retain more organic Se than inorganic Se. Bio-transformation is a major approach to transform inorganic Se to organic Se. Cordyceps gunnii (C. gunnii), well known as a Chinese edible and medicinal fungus, has a variety of biological functions. C. gunnii and selenium were combined through liquid-fermentation to obtain selenium-enriched C. gunnii. A novel Se-polysaccharide (SeCPS-II) was extracted from selenium-enriched C...

Methotrexate (MTX) is a classical chemotherapeutic agent with nephrotoxicity as the most disturbing adverse effect. So far, its underlying molecular mechanisms, particularly PI3K/Akt/eNOS transduction, are inadequately explored. Several antioxidant modalities have been characterized to ameliorate MTX-induced renal injury. In this regard, Camel milk (CM) is a natural product with recognized antioxidant and anti-inflammatory features. Thus, the current study aimed to investigate the potential ameliorating effects of CM in MTX-induced kidney injury in rats...

Prostate cancer is the most common male reproductive system cancer. The prevalence of prostate cancer in Europe and the United States is higher than that in the Asian region. However, the treatment of prostate cancer remains unsatisfactory. Psoralea corylifolia has been used to cure this disease as Chinese medicine in the Asian region. In this study, we analyzed the components of ethanol extraction of unprepared and prepared P. corylifolia by HPLC. Psoralen and isopsoralen content from the prepared P. corylifolia is twofold higher than that from unprepared, so we use the prepared extraction in this study...

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressive memory decline. It has been suggested that 5-hydroxytryptamine receptor 6 (5-HT6R) might be involved in AD pathology. The aim of this study was to evaluate the effect of a 5-HT6R antagonist on cognition, learning, memory, and hippocampal apoptosis in an experimental rat model of AD. AD was induced by intracerebroventricular (icv) administration of streptozotocin (STZ; 3 mg/kg, 10 μL, twice). Adult, male rats were divided into the following groups: control, sham, AD (saline treatment, 1 μL icv for 30 days), and AD + SB258585 (5-HT6R antagonist, 1 μg/μL icv for 30 days)...

PURPOSE: MLN4924 is a second-generation inhibitor that targets ubiquitin-proteasome system by inhibiting neddylation activation enzyme (NAE), and subsequently blocking the neddylation-dependent activation of Cullin-RING E3 ligases (CRLs), which leads to the accumulation of CRLs substrates and hence, suppressing diverse tumor development. In this study, we investigated the potential application of this first-in-class inhibitor MLN4924 in the treatment of human renal cell carcinoma both in vitro and in vivo...

Chlamydia psittaci is an obligate intracellular pathogen that can cause zoonosis. Persistent C. psittaci infection can inhibit apoptosis in host cells, thus extending their survival and enabling them to complete their growth cycle. In this study, the antiapoptotic effects of persistent C. psittaci infection, induced by treatment with IFN-γ, were found to be associated with both the death receptor and the mitochondrial pathways of apoptosis. These effects were mediated by Bcl-2 family members, as evidenced by the decreased expression of proapoptotic proteins, such as tBid and Bim...

QiShenYiQi dripping pills (QSYQ), a traditional Chinese medicine, are commonly used to treat coronary heart disease, and QSYQ was recently approved as a complementary treatment for ischemic heart failure in China. However, only few studies reported on whether QSYQ exerts a protective effect on heart failure induced by pressure overload. In this study, we explored the role of QSYQ in a mouse model of heart failure induced by transverse aortic constriction (TAC). Twenty-eight C57BL/6J mice were divided into four groups: Sham + NS group, Sham + QSYQ group, TAC + NS group, and TAC + QSYQ group...

Failure to precisely repair DNA damage in self-renewing Hematopoietic Stem and early Progenitor Cells (HSPCs) can disrupt normal hematopoiesis and promote leukemogenesis. Although HSPCs are widely considered a target of ionizing radiation (IR)-induced hematopoietic injury, definitive data regarding cell death, DNA repair, and genomic stability in these rare quiescent cells are scarce. We found that irradiated HSPCs, but not lineage-committed progenitors (CPs), undergo rapid ATM-dependent apoptosis, which is suppressed upon interaction with bone-marrow stroma cells...

p21WAF1/CIP1 is a broad-acting cyclin-dependent kinase inhibitor. Its stability is essential for proper cell-cycle progression and cell fate decision. Ubiquitylation by the multiple E3 ubiquitin ligase complexes is the major regulatory mechanism of p21, which induces p21 degradation. However, it is unclear whether ubiquitylated p21 can be recycled. In this study, we report USP11 as a deubiquitylase of p21. In the nucleus, USP11 binds to p21, catalyzes the removal of polyubiquitin chains conjugated onto p21, and stabilizes p21 protein...

Altered protein function due to mutagenesis plays an important role in disease development. This is perhaps most evident in tumorigenesis and the associated loss or gain of function of tumor-suppressor genes and oncogenes. The extent to which lesion-induced transcriptional mutagenesis (TM) influences protein function and its contribution to the development of disease is not well understood. In this study, the impact of O 6 -methylguanine on the transcription fidelity of p53 and the subsequent effects on the protein's function as a regulator of cell death and cell-cycle arrest were examined in human cells...
