Unusual DNA binding modes for metal anticancer complexes [PDF]
, 2009 DNA is believed to be the primary target for many metal-based drugs. For example, platinum-based anticancer drugs can form specific lesions on DNA that induce apoptosis.

From Yeast to Therapeutics: Modeling Neurodegenerative Diseases in Saccharomyces cerevisiae
Yeast, EarlyView.Yeast plasmids expressing human Aβ‐42, α‐syn, htt, and TDP‐43. Their fate includes an equilibrium between the endocytic pathway and aggregates that potentially disrupt endocytosis, vesicular transport, vacuolar autophagy, and mitochondrial activity. ABSTRACT Here, we review the use of Saccharomyces cerevisiae as a powerful model organism for studying ...

Translational Remodeling of the Synaptic Proteome During Aging
Aging Cell, EarlyView.Aging induces a decoupling of protein regulation between the soma and the synapse. In particular, transcripts coding for ribosomal proteins decrease and their corresponding proteins increase in the synapse while the opposite happens in the soma. At the same time, synapse‐specific regulation of splicing takes place.

Atypical Rho GTPases of the RhoBTB Subfamily: Roles in vesicle trafficking and tumorigenesis [PDF]
, 2016 RhoBTB proteins constitute a subfamily of atypical Rho GTPases represented in mammals by RhoBTB1, RhoBTB2, and RhoBTB3. Their characteristic feature is a carboxyl terminal extension that harbors two BTB domains capable of assembling cullin 3-dependent ...

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.

Interaction of Gα₁₂ with Gα₁₃ and Gα_q signaling pathways [PDF]
, 2002 The G(12) subfamily of heterotrimeric G-proteins consists of two members, G(12) and G(13). Gene-targeting studies have revealed a role for G(13) in blood vessel development. Mice lacking the a subunit of G(13) die around embryonic day 10 as the result of
