The effect of alpha-tocopherol on the oxidative cleavage of beta-carotene
(Elsevier B.V., 2000-07-15)
Two cleavage pathways of beta-carotene have been proposed, one by central cleavage and the other by random (excentric) cleavage. The central cleavage pathway involves the metabolism of beta-carotene at the central double ...
Estrogen receptor beta (ER beta) mediates expression of beta-catenin and proliferation in prostate cancer cell line PC-3
(Elsevier Ireland Ltd, 2016)
The aim of the present study was to characterize the mechanism underlying estrogen effects on the androgen-independent prostate cancer cell line PC-3. 17 beta-estradiol and the ER beta-selective agonist DPN, but not the ...

Differential effects of beta 1 and beta 2 subunits on BK channel activity
(ROCKEFELLER UNIV PRESS, 2005-04)
High conductance, calcium- and voltage-activated potassium (BK) channels are widely expressed in mammals. In some tissues, the biophysical properties of BK channels are highly affected by coexpression of regulatory (beta) ...

Dihydro-β-agarofuran sesquiterpenes isolated from Celastrus vulcanicola as potential anti-Mycobacterium tuberculosis multidrug-resistant agents
(Elsevier, 2011)
In the present study, we report four new dihydro-β-agarofuran sesquiterpenes (1-4), which were isolated from the leaves of Celastrus vulcanicola, in addition to five derivatives (5-9). Their stereostructures were elucidated ...
A NEW EREMOPHILANOLIDE FROM SENECIO ATACAMENSIS
(Sociedad Chilena de Química, 2000)
Purification and biochemical characterization of a mycelial glucose- and xylose-stimulated beta-glucosidase from the thermophilic fungus Humicola insolens
(ELSEVIER SCI LTD, 2010)
A mycelial beta-glucosidase from the thermophilic mold Humicola insolens was purified and biochemically characterized. The enzyme showed carbohydrate content of 21% and apparent molecular mass of 94 kDa, as estimated by ...
Absence of transforming growth factor-beta type II receptor is associated with poorer prognosis in HER2-negative breast tumours
(Oxford University Press, 2010-04-01)
Background: The clinical relevance of transforming growth factor-beta (TGF-beta)-signalling pathway in breast carcinomas (BCs) remained elusive. This study aimed to evaluate the prognostic value of TGF-beta and transforming ...
