Cell Intrinsic and Extrinsic Mechanisms of Caveolin-1-Enhanced Metastasis

Biomolecules, 2019
Caveolin-1 (CAV1) is a scaffolding protein with a controversial role in cancer. This review will initially discuss earlier studies focused on the role as a tumor suppressor before elaborating subsequently on those relating to function of the protein as a

Kinetics of Phenotypic and Functional Changes in Mouse Models of Sponge Implants: Rational Selection to Optimize Protocols for Specific Biomolecules Screening Purposes

Frontiers in Bioengineering and Biotechnology, 2020
The sponge implant has been applied as an important in vivo model for the study of inflammatory processes as it induces the migration, proliferation, and accumulation of inflammatory cells, angiogenesis, and extracellular matrix deposition in its ...

An arbuscular mycorrhiza from the 407‐million‐year‐old Windyfield Chert identified through advanced fluorescence and Raman imaging

New Phytologist, Volume 249, Issue 1, Page 448-459, January 2026.
Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

Reprogramación celular

Biotempo, 2017
Pocos avances recientes han revolucionado tanto la biología del desarrollo como la reprogramación de células por transferencia nuclear. Desde 1952 a la fecha, se ha acumulado suficiente información teórica así como tecnologías de avanzada, para desmitificar el paradigma de la irreversibilidad de la diferenciación celular.

Climate and hybridization shape stomatal trait evolution in Populus

New Phytologist, Volume 249, Issue 2, Page 792-809, January 2026.
Summary Stomata play a critical role in regulating plant responses to climate. Where sister species differ in stomatal traits, interspecific gene flow can influence the evolutionary trajectory of trait variation, with consequences for adaptation. Leveraging six latitudinally distributed contact zones spanning the natural hybrid zone between Populus ...

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

New Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their
