uORF-targeting steric block antisense oligonucleotides do not reproducibly increase RNASEH1 expression.

Upstream open reading frames (uORFs) are -regulatory motifs that are predicted to occur in the 5' UTRs of the majority of human protein-coding transcripts and are typically associated with translational repression of the downstream primary open reading frame (pORF). Interference with uORF activity provides a potential mechanism for targeted upregulation of the expression of specific transcripts. It was previously reported that steric block antisense oligonucleotides (ASOs) can bind to and mask uORF start codons to inhibit translation initiation, and thereby disrupt uORF-mediated gene regulation.

Pharmacological and neuroprotective profile of an essential oil derived from leaves of Aloysia citrodora Palau.

Objectives: The Jordanian 'Melissa', (Aloysia citrodora) has been poorly studied both pharmacologically and in the clinic. Essential oils (EO) derived from leaves of A. citrodora were obtained by hydrodistillation, analysed by gas chromatography-mass spectrometry (GC-MS) and were investigated for a range of neurobiological and pharmacological properties, as a basis for potential future use in drug discovery.

Effects of methimepip and JNJ-5207852 in Wistar rats exposed to an open-field with and without object and in Balb/c mice exposed to a radial-arm maze.

The role of the histamine H(3) receptor (H(3)R) in anxiety is controversial, due to limitations in drug selectivity and limited validity of behavioral tests used in previous studies. In the present report, we describe two experiments. In the first one, Wistar rats were treated with an H(3)R agonist (methimepip), and exposed to an open-field.
