Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

What have we learned from two-pore potassium channels? Their molecular configuration and function in the human heart [PDF]

, 2012
Two-pore domain potassium channels (K2P) control excitability, stabilize the resting membrane potential below firing threshold, and accelerate repolarisation in different cells.

Cytohesin 2/ARF6 regulates preadipocyte migration through the activation of ERK1/2 [PDF]

, 2014
Preadipocyte migration is vital for the development of adipose tissue, which plays a crucial role in lipid metabolism. ADP-ribosylation factor 6 (ARF6) small GTPase, which regulates membrane trafficking, is activated by GTP-exchange factors (GEFs) such ...

The leishmania ARL-1 and Golgi traffic. [PDF]

PLoS ONE, 2008
We present here the characterisation of the Leishmania small G protein ADP-Ribosylation Factor-Like protein 1 (ARL-1). The ARL-1 gene is present in one copy per haploid genome and conserved among trypanosomatids.

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Clostridial binary toxins: iota and C2 family portraits

Frontiers in Cellular and Infection Microbiology, 2011
There are many pathogenic Clostridium species with diverse virulence factors that include protein toxins. Some of these bacteria, such as C. botulinum, C. difficile, C. perfringens and C. spiroforme, cause enteric problems in animals as well as humans.

Automodification of N‐terminal serine residues facilitates PARP2 release from DNA

The FEBS Journal, EarlyView.
PARP2 is involved in detecting DNA damage and its N‐terminal role is largely unknown. Based on biochemical and biophysical data, our findings suggest that in the presence of HPF1, N‐terminal serine 8 and 73 are enriched in auto‐ADP‐ribosylation. Our results provide insight into the mechanistic role of PARP2 N‐terminus in the PARylation‐dependent ...

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Synergistic RU486 and olaparib therapy enhances apoptosis in endometriosis by simultaneously targeting hormonal signalling and DNA repair

British Journal of Pharmacology, Volume 183, Issue 11, Page 2947-2968, June 2026.
Background and Purpose Endometriosis is a chronic, hormone‐dependent disorder characterized by ectopic implantation of endometrial tissue, often accompanied by pain and infertility. Although the progesterone receptor modulator RU486 is effective for pain relief, its impact on lesion regression is limited, possibly due to apoptosis resistance and ...

Compartmentalization of distinct cAMP signaling pathways in mammalian sperm. [PDF]

, 2013
Fertilization competence is acquired in the female tract in a process known as capacitation. Capacitation is needed for the activation of motility (e.g. hyperactivation) and to prepare the sperm for an exocytotic process known as acrosome reaction. While
