An object of the present invention is to clarify unelucidated aspects in the control mechanism of circadian rhythms. The present inventors have newly found that RORα (retinoic acid binding-receptor alpha; the same shall apply hereinafter) stimulates an induction of Bmal1 expression and also that the induction of Bmal1 expression is promoted under hypoxia. These findings strongly suggest the existence of a control mechanism of circadian rhythms that, when RORα expression is promoted under hypoxia or the like, an induction of Bmal1 expression is stimulated and, when the induction of Bmal1 expression is stimulated, binding between BMAL1 and CLOCK is stimulated and an induction of Per gene or Cry gene expression is stimulated. The present invention, therefore, has applicability as jet-lag regulating agents and anticancer agents.
摘要:
In a cell detecting part (2), and end face (13a) of a cantilever (13) is previously surface treated so that a detecting nucleotide chain D can be fixed thereto. In a reaction area (10), and electric field is generated by a cathode (11) and an anode (12). A target nucleotide chain T dripped from a nozzle (3) moves to the end face (13a) while the target nucleotide chain T is stretched. When the detecting nucleotide chain D and the target nucleotide chain T are hybridized, the mass of the cantilever (13) is increased to lower a natural frequency. Thus, ac voltage is applied to the cantilever (13) to measure the change of the natural frequency. Thus, whether or not there is the hybridization is detected and the number of the hybridized target nucleotide chains T is quantitatively detected.

摘要:
A bioassay substrate (1) is flat and has a disc-shaped main side like an optical disc such as CD. The substrate (1) is rotatable about a central hole (2) formed therein. The substrate (1) has formed on the surface (1a) thereof a plurality of wells (8) where a probe-use DNA (detection-use nucleotide chain) and sample-use DNA (target nucleotide chain) react with each other for hybridization. The substrate (1) has a transparent electrode layer (4) formed as an underlying layer of the well (8). For hybridization, an external electrode (18) is placed in a position near the transparent electrode layer (4) from above the top surface (1a) of the substrate (1) to apply an AC power to between the transparent electrode layer (4) and external electrode (18) in order to apply an AC electric field perpendicularly to the substrate (1).
摘要:
Disclosed herein is a method and apparatus for determining the base sequence of a nucleic acid molecule by cleaving a nucleic acid molecule of interest while controlling the cleavage site, measuring the change in mass which occurs in the nucleic acid molecule after the cleavage step, and acquiring the base information of the cleaved nucleic acid molecule from the data about the change in mass. The method and apparatus are based on the principle which is entirely different from that used for the conventional technique.

摘要:
To verify an action of a high-frequency ac electric field on a single-stranded nucleic acid existing in an aqueous solution. This action is used to improve the efficiency of hybridization to which the single-stranded nucleic acid is subjected as a complementary strand. Provided are a method and system for stretching a single-stranded nucleic acid, which exists in a free form in pure water or an aqueous solution (R) of pH 5 to 11, or which exists in a form immobilized on one of surface (f) of an electrode (E) of opposing electrodes (E,E) arranged facing the aqueous solution (R) or in a form immobilized on surfaces (f) of both electrodes (E) of opposing electrodes (E, E), by causing a high-frequency ac electric field to act on the single-stranded nucleic acid.
