Chemoprevention in experimental animals [PDF]

open access: yesAnnals of the New York Academy of Sciences, 2011
The potential cancer‐preventive effects of resveratrol, evident from the data obtained by various studies, are summarized in this review. Resveratrol (trans‐3,5,4′‐trihydroxystilbene), a naturally occurring polyphenolic compound, was first isolated in 1940 as a constituent of the roots of white Hellebore (Veratrum grandiflorumO. Loes), and is now found

STAT3 expression is reduced in cardiac pericytes in HFpEF and its loss reduces cellular adhesion and induces pericyte senescence

open access: yesFEBS Letters, EarlyView.
Heart failure with preserved ejection fraction (HFpEF) accounts for half of the heart failure cases. It is characterised by microvascular dysfunction, associated with reduced pericyte coverage and diminished STAT3 expression in pericytes. Loss of STAT3 impairs pericyte adhesion, promotes senescence, and activates a pro‐fibrotic gene program.

Alternatives to Laboratory Animals: Definition and Discussion [PDF]

open access: yes, 1979
The origins of the concept of alternatives to the use of animals in research may be traced back to the 1800\u27s and the furore about using live animals in surgical and other experiments. Some of the animal protection societies in England were prepared

Ion channel function of polycystin‐2/polycystin‐1 heteromer revealed by structure‐guided mutagenesis

open access: yesFEBS Letters, EarlyView.
Mutations in polycystin‐1 (PC1) or polycystin‐2 (PC2) cause autosomal‐dominant polycystic kidney disease (ADPKD). We generated a novel gain‐of‐function PC2/PC1 heteromeric ion channel by mutating pore‐blocking residues. Moreover, we demonstrated that PC2 will preferentially assemble with PC1 to form heteromeric complexes when PC1 is co‐expressed ...

Animal voices: Catherine Louisa Pirkis'The Experiences of Loveday Brooke, Lady Detective and the crimes of animality [PDF]

open access: yes, 2018
While previous readings of Catherine Louisa Pirkis’ series The Experiences of Loveday Brooke, Lady Detective (1894) have focused on Brooke’s status as New Woman detective, this article considers the series in the context of Pirkis’ own ...

Protonophore activity of short‐chain fatty acids induces their intracellular accumulation and acidification

open access: yesFEBS Letters, EarlyView.
The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Asbestosis in Experimental Animals [PDF]

open access: yesOccupational and Environmental Medicine, 1963
Previous animal experiments with asbestos dusts have been almost entirely confined to chrysotile asbestos. It was, therefore, decided to investigate the effects of mill dusts from the three types of asbestos that are produced commercially in South Africa, namely chrysotile, amosite, and crocidolite.

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Modifications in FLAP's second cytosolic loop influence 5‐LOX interaction, inhibitor binding, and leukotriene formation

open access: yesFEBS Letters, EarlyView.
The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).
