An ecometric analysis of the fossil mammal record of the Turkana Basin

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2016
Although ecometric methods have been used to analyse fossil mammal faunas and environments of Eurasia and North America, such methods have not yet been applied to the rich fossil mammal record of eastern Africa.

Therapsids as Mammals [PDF]

open access: yesEvolution, 1960
The therapsids are usually placed in the class Reptilia as its most mammal-like representatives. This is on the basis of the now commonly accepted criteria of jaw-ear structure, where mammals are defined as having (1) a dentary-squamosal suspensorium, (2) the articularquadrate joint not a mandibular suspensorium, (3) three middle ear bones, and (4) the

Multidimensional OMICs reveal ARID1A orchestrated control of DNA damage, splicing, and cell cycle in normal‐like and malignant urothelial cells

open access: yesMolecular Oncology, EarlyView.
Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

Research Note. Trichinella spiralis parasitizing Puma concolor: first record in wildlife in Chile

open access: yesHelminthologia, 2015
The genus Trichinella is widespread in all continents but Antarctica. The only way to identify the species/genotypes is through molecular analyses. In Chile, only one study has reported Trichinella larvae in a cougar, but the species of Trichinella was ...

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

open access: yesMolecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

TRPM8 levels determine tumor vulnerability to channel agonists

open access: yesMolecular Oncology, EarlyView.
TRPM8 is a Ca2+ permissive channel. Regardless of the amount of its transcript, high levels of TRPM8 protein mark different tumors, including prostate, breast, colorectal, and lung carcinomas. Targeting TRPM8 with channel agonists stimulates inward calcium currents followed by emptying of cytosolic Ca2+ stores in cancer cells.

Quantification of argyrophillic, argentaffin and insulin immunoreactive cells in the small intestine in the opossum Didelphis aurita (Wied-Neuwied, 1826) - doi: 10.4025/actascibiolsci.v33i4.8644

open access: yesActa Scientiarum: Biological Sciences, 2011
The objective of this study was to quantify argyrophillic, argentaffin and insulin immunoreactive endocrine cells in the different segments of the small intestine of Didelphis aurita and measure probable differences in the number of these cells between ...

Systematic profiling of cancer‐fibroblast interactions reveals drug combinations in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Fibroblasts, cells in the tumor environment, support ovarian cancer cell growth and alter morphology and drug response. We used fibroblast and cancer cell co‐culture models to test 528 drugs and discovered new drugs for combination treatment. We showed that adding Vorinostat or Birinapant to standard chemotherapy may improve drug response, suggesting ...

A nucleotide‐independent, pan‐RAS‐targeted DARPin elicits anti‐tumor activity in a multimodal manner

open access: yesMolecular Oncology, EarlyView.
We report a Designed Ankyrin Repeat Protein that binds and inhibits RAS proteins, which serve as central cell signaling hubs and are essential for the progression of many cancers. Its unique feature is that it does not discriminate between different RAS isoforms or mutations and is capable of binding to RAS in both its active (GTP‐bound) and inactive ...
