Overexpression of Bcl-2 in myeloma cells results in resistance to drugs such as dexamethasone (DEX), adenovirus-mediated delivery of p53 (Ad-p53), and paclitaxel (TAX), which work through the intrinsic apoptotic pathway. Bcl-2 antisense oligodeoxynucleotides (Bcl-2-ASO) have been shown to induce apoptosis in cancer cells, as a single agent or, better, in combination with chemotherapy. We hypoth...

Background. Gastrin regulates growth of human colon cancer cells by activation of the cyclic adenosine monoPhosphate (cAMP) -dependent protein kinase A (PKA). Gastrin and 8-Br-cAMP, a membrane-permeable cAMP analag, inhibit growth of HCT116 cells,' both stimulate growth of LoVo cells. This dualeffecton growth may be explained by relative amounts of the regulatory subunit (Rla or RIIP) of PKA wi...

The 5-hydroxytryptamine (5-HT)2A receptor is an important component of the neural substrates underlying ethanol (EtOH) intake and behaviors related to anxiety and stress. Paradoxically, both 5-HT2A agonists and antagonists have been shown to reduce EtOH intake, however the mechanisms underlying these effects are not understood. This inconsistency could possibly be explained by their chronic dow...

Three commercial systems were compared for ability to detect antibodies to streptolysin O (ASO) and DNase B (ADB). Streptozyme (Wampole Laboratories, Cranbury, N.J.) exhibited high sensitivity (100%) for detecting ASO but low sensitivity for ADB (22.2%). The LeapStrep (Organon Teknika, Malvern, Pa.) and Check-Spectra (Diagnostic Technology, Hauppauge, N.Y.) tests had low sensitivities for detec...

BACKGROUND D-transposition of the great arteries (TGA) with left ventricular outflow tract obstruction (LVOTO) may be treated with arterial switch operation (ASO) with or without LVOT intervention, as well as non-ASO anatomic repairs, such as aortic translocation or Rastelli procedure. We evaluated midterm results of repair for TGA/LVOTO at our institution. METHODS AND RESULTS Eighty-eight pa...

To investigate the possible role of eukaryotic initiation factor 4E-binding protein-2 (4E-BP2) in metabolism and energy homeostasis, high-fat diet-induced obese mice were treated with a 4E-BP2-specific antisense oligonucleotide (ASO) or a control 4E-BP2 ASO at a dose of 25 mg/kg body wt or with saline twice a week for 6 wk. 4E-BP2 ASO treatment reduced 4E-BP2 levels by >75% in liver and white (...

CONTEXT The GH receptor (GHR) pseudoexon 6Psi defect is a frequent cause of GH insensitivity (GHI) resulting from a non-functioning GH receptor (GHR). It results in a broad range of phenotypes and may also be present in patients diagnosed as idiopathic short stature. OBJECTIVE Our objective was to correct aberrant GHR splicing and inclusion of 6Psi using exon-skipping antisense oligonucleotid...

Allele-specific oligonucleotide real-time quantitative PCR (ASO-RQPCR) is a standardized technique for detection and monitoring of minimal residual disease (MRD) in acute lymphoblastic leukemia (ALL) but not multiple myeloma (MM) due to a low applicability inherent with presence of somatic hypermutation. Herein, by a staged PCR approach and sequencing, clonality and tumor-specific complementari...

Lipid droplets in the liver are coated with the perilipin family of proteins, notably adipocyte differentiation-related protein (ADRP) and tail-interacting protein of 47 kDa (TIP47). ADRP is increased in hepatic steatosis and is associated with hyperlipidemia, insulin resistance, and glucose intolerance. We have shown that reducing ADRP in the liver via antisense oligonucleotide (ASO) treatment...
