Colony stimulating factor-1 (CSF-1) is one of the most common proinflammatory cytokine responsible for various inflammatory disorders. It has a remarkable role in the development and progression of osteoarthritis, cancer and other autoimmune disease conditions. The CSF-1 acts by binding to the receptor, called colony stimulating factor-1 receptor (CSF-1R) also known as c-FMS resulting in the cascade of signalling pathway causing cell proliferation and differentiation. Interleukin-34 (IL-34), recently identified as another ligand for CSF-IR, is a cytokine protein...

OBJECTIVES: Breast cancer stem cells (BCSCs) contribute to breast cancer progression, relapse, and treatment resistance. Identification of the natural inhibitory components of BCSCs is therefore critical for clinical treatment. Here, we investigated whether isoharringtonine (IHT) had inhibitory effects on BCSCs in breast cancer cell lines. METHODS: HCC1806, HCC1937, and MCF7 cells were treated with IHT. The proliferation and the migration of cells were detected by MTS assay and wound healing migration assay, respectively...

Opioid-induced respiratory depression is a major obstacle to improving the clinical management of moderate to severe chronic pain. Opioids inhibit neuronal activity via various pathways, including calcium channels, adenylyl cyclase, and potassium channels. Currently, the underlying molecular pathway of opioid-induced respiratory depression is only partially understood. This study aimed to investigate the mechanisms of opioid-induced respiratory depression in vivo by examining the effects of different pharmacological agents on fentanyl-induced respiratory depression...

BACKGROUND: Inhibitory receptor programmed cell death protein-1 (PD-1) is upregulated on a variety of immune cells, including natural killer (NK) cells, during chronic virus infection and tumorigenesis. Blockade of PD-1 or its ligands produces durable clinical responses with tolerable side effects in patients with a broad spectrum of cancers. However, the underlying molecular mechanisms of how PD-1 regulates NK cell function remain poorly characterized. OBJECTIVE: We sought to determine what effect PD-1 signaling has on NK cells...

Esophageal squamous cell carcinoma (ESCC) is the most common form of esophageal cancer in China. Since chemotherapy is the standard clinical intervention for advanced ESCC, the development of highly effective and minimal/non-toxic drugs is essential to improve the clinical outcome and prognosis of the patients. A novel derivative of vanillin, 6-bromine-5-hydroxy-4-methoxybenzaldehyde (BVAN08), has been recently reported to activate different cell death pathways in cancer cells. In this study, we demonstrate that BVAN08 exhibits a potent anti-proliferation effect on ESCC cells (TE-1 and ECA-109) by inhibiting the expression of PLK1, an important mitotic kinase...

Long non-coding RNAs (lncRNAs) are non-protein-coding transcripts shown to play important roles in tumourigenesis and tumour progression. Our study aimed to examine expression of the lncRNA MAGI2-AS3 in breast cancer and to explore its function in cancer cell growth. First, MAGI2-AS3 expression levels in clinical samples and cell lines were determined by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The functional significance of MAGI2-AS3 in cancer cell proliferation and apoptosis was then examined in vitro...

The epidemic of nonalcoholic fatty liver disease (NAFLD) has created a real and unmet therapeutic need. The long regulatory pathway and the focus on selected subsets of patients with established and advanced disease are some of the current obstacles to providing effective treatment for the majority of NAFLD patients. The complexity of the disease pathogenesis, which involves multiple mechanisms, requires targeting of more than one pathway or a combination-based therapy. Although the drugs being developed may prevent progression to cirrhosis or may decrease negative liver outcomes, their effects on cardiometabolic health and cancer prevention remain unknown...

Molecular alterations reflecting pathophysiologic changes thought to occur many years before the clinical onset of Machado-Joseph disease (MJD)/spinocerebellar ataxia type 3 (SCA3), a late-onset polyglutamine disorder, remain unidentified. The absence of molecular biomarkers hampers clinical trials, which lack sensitive measures of disease progression, preventing the identification of events occurring prior to clinical onset. Our aim was to analyse the mtDNA content and the amount of the common deletion (m...

To review recent scientific advances and therapeutic approaches in the expanding field of type I interferonopathies. Type I interferonopathies represent a genetically and phenotypically heterogenous group of disorders of the innate immune system caused by constitutive activation of antiviral type I interferon (IFN). Clinically, type I interferonopathies are characterized by autoinflammation and varying degrees of autoimmunity or immunodeficiency. The elucidation of the underlying genetic causes has revealed novel cell-intrinsic mechanisms that protect the organism against inappropriate immune recognition of self nucleic acids by cytosolic nucleic acid sensors...

BACKGROUND: Lung cancer is the leading cause of cancer-related death in both men and women. KRAS mutations occur in ~ 25% of patients with lung cancer, and the presence of these mutations is associated with a poor prognosis. Unfortunately, efforts to directly target KRAS or its associated downstream MAPK or PI3K/AKT/mTOR pathways have seen little or no benefits. Here, I hypothesize that KRAS-mutant tumors do not respond to KRAS pathway therapies due to the co-occurrence of other activated cell survival pathways and/or mechanisms...

Marjana Rahman Sarker, Susan F Franks
Processes such as aberrant redox signaling and chronic low-grade systemic inflammation have been reported to modulate age-associated pathologies such as cognitive impairment. Curcumin, the primary therapeutic component of the Indian spice, Turmeric (Curcuma longa), has long been known for its strong anti-inflammatory and antioxidant activity attributable to its unique molecular structure. Recently, an interest in this polyphenol as a cognitive therapeutic for the elderly has emerged. The purpose of this paper is to critically review preclinical and clinical studies that have evaluated the efficacy of curcumin in ameliorating and preventing age-associated cognitive decline and address the translational progress of preclinical to clinical efficacy...

BACKGROUND: Metastasis-Associated in Colon Cancer-1(MACC1) was first identified as a transcriptional activator of the HGF/MET pathway. Deregulation of HGF/MET signaling is reported as a prognostic marker for tumorigenesis, early stage invasion, and metastasis which is associated with poor clinical outcome in breast cancer patients. The aim of the present study was to further investigate the prognostic or predictive value of MACC1 expression in breast cancer. MATERIALS AND METHODS: We analyzed the MACC1 expression in 105 primary breast cancer samples by Western-Blot analysis and immunohistochemistry...

Cardiovascular disease, despite all the recent advances in treatment of the various risk factors, remains the major cause of mortality in both type 1 and type 2 diabetes. Experimental models of diabetes-associated atherosclerosis, despite their limitations in recapitulating the human context, have assisted in the elucidation of molecular and cellular pathways implicated in the development and progression of macrovascular injury in diabetes. Our own studies have emphasized the role of oxidative stress and advanced glycation and identified potential targets for vasoprotective therapies in the setting of diabetes...

Triple negative breast cancer (TNBC) is a highly aggressive tumor subtype, lacking estrogen, progesterone and human epidermal growth factor-2 (HER-2) receptors. Thus, early detection and targeted therapy of TNBC is an urgent need. Herein, we have developed a CD44 targeting Hyaluronic Acid (HA) decorated biocompatible oligomer, containing FDA approved vitamin E TPGS and Styrene Maleic Anhydride (SMA) (HA-SMA-TPGS) for targeting TNBC. The self-assembling HA-SMA-TPGS was encapsulated with poorly water soluble, potent curcumin analogue (CDF) to form nanomicelles (NM), HA-SMA-TPGS-CDF has demonstrated excellent nanoparticle charateristics for parenteral delivery...

Changes in the protein expression occurring within the initiation phase of acute pancreatitis (AP) might be vital in the development of this complex disease. However, the exact mechanisms involved in the onset of AP remains elusive and most of our knowledge about the pathobiology of AP comes from animal models. We performed in a rat pancreatitic model a high-throughput shotgun proteomic profiling of the soluble and whole membrane fractions from the pancreas during the early phase of cerulein (Cer)-induced AP...

The mesenchymal (MES) subtype of glioblastoma (GBM) suggested worseprognosis and a more malignant phenotype in comparison with their proneural (PN) counterpart. The plasticity between PN and MES transcriptome signatures provided clinical intervention with an manner. Few LncRNA, however, have been discovered to take part in the shift between subtypes. Here, we used transcriptomic data and experimental evidences to demonstrate that silencing LncRNA LOXL1-AS1 was a new regulator of NF-κB signaling pathway through repressing RELB directly, resulting in increased marker genes of PN subtype and decreased those of MES...

PBX1 was abnormally overexpressed and its intracellular localization was found to be frequently amplified in many types of cancer, including renal clear cell carcinoma. PBX1 displays oncogenic activity in several different types of cells, but little is known about how signaling pathways are altered, and the function of PBX1 in renal clear cell carcinoma has not been well investigated. In this study, we demonstrate that the expression of PBX1 was significantly upregulated in 30 pairs of human tissues compared to adjacent normal tissues and the overall survival rate of PBX1-high group was significantly worse than that of PBX1-low group...
