Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

open access: yesMolecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

The Eclipse to Confirm the General Theory of Relativity [PDF]

open access: yes, 2015
One of the milestones of the science of light commemorated during this International Year of Light and Light-based Technologies is “the embedding of light in cosmology through general relativity in 1915,” that is, the celebration of the centenary of ...

Einstein, Gödel, Heidegger. Some observations about the concept of time

open access: yesPensamiento. Revista de Investigación e Información Filosófica, 2013
In this article we focus on some of the paths which help us to understand the philosophical question of time. The interpretative frame is composed of Einstein’s theory of relativity, against which we have the observations of Gödel and Heidegger on this ...

Can Lorentz transformations be determined by the null Michelson-Morley result?

open access: yesRevista Brasileira de Ensino de Física
The so-called principle of relativity is able to fix a general coordinate transformation which differs from the standard Lorentzian form only by an unknown speed which cannot in principle be identified with the light speed.

L’essenza fenomenologica della relatività. Questioni di confine tra Husserl e Einstein [PDF]

open access: yesS&F_scienzaefilosofia.it, 2016
The phenomenological Essence of Relativity. Matters concerning the Border between Husserl and Einstein According to Hermann Weyl, Einstein’s Relativity Theory is a method that combines “analysis of essence” and “mathematical construction”.

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

open access: yesMolecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

open access: yesMolecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

An Extreme Rotating Black Hole in New Massive Gravity Theory

open access: yesRevista Politécnica, 2017
New Massive Gravity is an alternative theory to General Relativity that is used to describe the gravitational field in a (2+1)-dimensional spacetime. Black hole solutions have been found in this theory, in particular an asymptotically anti-de Sitter ...

Spacetime Emergence: An (In)effective Story

open access: yesPhilosophy of Physics
Physicists and philosophers are increasingly prone to regarding our current physical theories as providing ‘effective descriptions’ of real-world systems.
