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.

Inherent structural disorder and dimerisation of murine norovirus NS1-2 protein [PDF]

open access: yes, 2012
Human noroviruses are highly infectious viruses that cause the majority of acute, non-bacterial epidemic gastroenteritis cases worldwide. The first open reading frame of the norovirus RNA genome encodes for a polyprotein that is cleaved by the viral ...

Human protein S cDNA encodes Phe‐16 and Tyr 222 in consensus sequences for the post‐translational processing

open access: yesFEBS Letters, 1987
Partial cDNAs coding for human protein S were isolated from a pUC9 human liver cDNA library. Together, the overlapping clones span a (partial) 5′‐non‐coding region, and the complete protein S coding and 3′‐untranslated regions. The derived amino acid sequence deviates at five positions from two previously reported protein S sequences.

Circulating microRNA signatures of cachexia and cancer in Canis familiaris as a comparative oncology model for human disease

open access: yesMolecular Oncology, EarlyView.
Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Studies of protein post-translational modifications using high resolution tandem mass spectrometry [PDF]

open access: yes
Electron capture dissociation (ECD) is a powerful and superior tandem mass spectrometry (MS) fragmentation technique in the study of protein post-translational modifications (PTMs) due to its unique features of preserving labile modifications and ...

The role of TNRC6 proteins in gene silencing [PDF]

open access: yes, 2013
Proteins of the GW182 family have recently emerged as key players in miRNAmediated gene silencing. They have been shown to interact with Argonaute proteins, components of the RISC and are assumed to mediate the repression in metazoa. Three paralogues are

Biological significance of complex N-glycans in plants and their impact on plant physiology

open access: yesFrontiers in Plant Science, 2014
Asparagine (N)-linked protein glycosylation is a ubiquitous co- and post-translational modification which can alter the biological function of proteins and consequently affects the development, growth and physiology of organisms.

From tumor‐centric to ecosystem‐based hypotheses in brain tumor research and care

open access: yesMolecular Oncology, EarlyView.
Primary brain tumors, whether in adults or children, present a major challenge because of their dramatic prognosis and the ongoing lack of efficient therapeutic approaches. In recent years, a shift has occurred from tumor‐centric concepts to a more holistic view of these tumors as dynamic ecosystems.

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

open access: yesMolecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Post-transcriptional control by bacteriophage T4: mRNA decay and inhibition of translation initiation

open access: yesVirology Journal, 2010
Over 50 years of biological research with bacteriophage T4 includes notable discoveries in post-transcriptional control, including the genetic code, mRNA, and tRNA; the very foundations of molecular biology.
