Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Mycobacteria modulate SUMOylation to suppresses protective responses in dendritic cells.

PLoS ONE, 2023
Post translational modifications (PTMs) are exploited by various pathogens in order to escape host immune responses. SUMOylation is one of the PTMs which is involved in regulation of a variety of cellular responses.

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

The Function of SUMOylation and Its Role in the Development of Cancer Cells under Stress Conditions: A Systematic Review

Stem Cells International, 2020
Malignant tumors still pose serious threats to human health due to their high morbidity and mortality. Recurrence and metastasis are the most important factors affecting patient prognosis.

SUMOylation in Trypanosoma brucei

PeerJ, 2013
Small ubiquitin like modifier (SUMO) proteins are involved in many processes in eukaryotes. We here show that Trypanosoma brucei SUMO (Tb927.5.3210) modifies many proteins. The levels of SUMOylation were unaffected by temperature changes but were increased by severe oxidative stress.

Geminiviral protein Rep interferes in PCNA sumoylation [PDF]

, 2015
Rep is a multifunctional protein essential for replication of geminivirus that interferes with the sumoylation of a key protein in the DNA replication, PCNA (Proliferating Cell Nuclear Antigen).

Srs2 mediates PCNA-SUMO-dependent inhibition of DNA repair synthesis [PDF]

, 2013
Completion of DNA replication needs to be ensured even when challenged with fork progression problems or DNA damage. PCNA and its modifications constitute a molecular switch to control distinct repair pathways. In yeast, SUMOylated PCNA (S-PCNA) recruits

Opening closed inward rectifier potassium channel doors

British Journal of Pharmacology, EarlyView.
Inwardly rectifying potassium (KIR) channels are essential regulators of membrane potential in excitable and non‐excitable tissues. Although KIR channels exhibit a biophysical preference for potassium influx due to voltage‐dependent block of outward current by polyamines and Mg2+, under physiological conditions, they predominantly mediate K+ efflux ...

Novel post-translational modifications in bone remodeling: potential therapeutic strategies for osteoporosis

European Cells & Materials
Osteoblast-induced bone formation and osteoclast-mediated bone resorption coordinate the balance of bone remodeling. However, the exact mechanisms underlying bone remodeling remain unknown.

Roles of TIF1β in Leukemic Stem Cell Through SETDB1‐Dependent and Independent Mechanisms

Cancer Science, EarlyView.
In leukemic stem cell, BCR::ABL cooperates with TIF1β to open chromatin at oncogenes and close chromatin at differentiation regulators, driving leukemic reprogramming. In TIF1β‐deficient stem cell, the loss of TIF1β inverts this balance, showing closed chromatin at oncogenes and open chromatin at differentiation regulators.
