Structures of Ras superfamily effector complexes: What have we learnt in two decades? [PDF]

open access: yes, 2015
The Ras superfamily small G proteins are master regulators of a diverse range of cellular processes and act via downstream effector molecules. The first structure of a small G protein-effector complex, that of Rap1A with c-Raf1, was published 20 years ...

Domain associated with zinc fingers‐containing NF90‐NF45 complex inhibits m6A modification of primary microRNA by suppressing METTL3/14 activity

open access: yesFEBS Open Bio, Volume 16, Issue 5, Page 921-931, May 2026.
NF90–NF45 functions as a negative regulator of methyltransferase‐like 3/14 (METTL3/14)‐mediated N6‐methyladenosine (m6A) modification on primary microRNAs (pri‐miRNAs). NF90–NF45 binds to anti‐oncogenic pri‐miRNAs and inhibits their m6A modification, thereby suppressing the biogenesis of anti‐oncogenic miRNAs.

Peroxiredoxin-mediated disulfide bond formation is required for nucleocytoplasmic translocation and secretion of HMGB1 in response to inflammatory stimuli

open access: yesRedox Biology, 2019
The nuclear protein HMGB1 (high mobility group box 1) is secreted by monocytes-macrophages in response to inflammatory stimuli and serves as a danger-associated molecular pattern.

Intercompartmental communication in senescence

open access: yesFEBS Open Bio, Volume 16, Issue 5, Page 837-856, May 2026.
Senescent cells experience structural changes in the plasma membrane, endoplasmic reticulum, mitochondria, lysosomes, nucleus, and cytoskeleton. These alterations disrupt crosstalk among cellular compartments, impairing vesicular trafficking, contact sites, and molecular flow.

4-Hydroxy-2-nonenal causes nuclear accumulation of p62 by inhibiting Xpo1 and promoting the proteolytic pathway in the nucleus.

open access: yesPLoS ONE
p62, an adapter protein involved in selective autophagy, is mainly found in the cytoplasm under normal conditions. Because p62 has nuclear localization signal (NLS) and a nuclear export signal, it has been suggested that p62 shuttles between the nucleus ...

Selinexor and Venetoclax Combination in Patients With Relapsed or Refractory Acute Myeloid Leukemia

open access: yesAmerican Journal of Hematology, Volume 101, Issue 5, Page 1019-1024, May 2026.
ABSTRACT Preclinical studies showed a synergistic antileukemia activity with combination of selective XPO1 inhibitor selinexor (SEL) and venetoclax (VEN), with potential to overcome VEN resistance by reducing the anti‐apoptotic protein MCL1. In an investigator‐sponsored, open‐label, phase Ib study (NCT03955783), adult patients with relapsed or ...

Deficiency of Pkc1 activity affects glycerol metabolism in Saccharomyces cerevisiae [PDF]

open access: yes, 2005
In pressProtein kinase C is apparently involved in the control of many cellular systems: the cell wall integrity pathway, the synthesis of ribosomes, the appropriated reallocation of transcription factors under specific stress conditions and also the ...

MicroRNA‐Mediated Regulation of Brain Aging Hallmarks: Implications for Neurodegeneration and Neural Recovery

open access: yesBrain and Behavior, Volume 16, Issue 5, May 2026.
Hallmarks of brain aging regulated by microRNAs (miRNAs). This graphical abstract illustrates the central role of miRNAs in coordinating key biological processes associated with brain aging. miRNAs regulate multiple interconnected hallmarks, including genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis and impaired ...
