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

FEBS 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.

Plant 4/1 protein: potential player in intracellular, cell-to-cell and long-distance signaling [PDF]

, 2014
Originally isolated as a result of its ability to interact with the movement protein of Tomato spotted wilt virus in a yeast two-hybrid system, the 4/1 protein is proving to be an excellent tool for studying intracellular protein trafficking and ...

New insights into YAP/TAZ nucleo‐cytoplasmic shuttling: new cancer therapeutic opportunities?

Molecular Oncology, 2019
Yes‐associated protein (YAP) and transcriptional co‐activator with PDZ‐binding motif (TAZ), the main effectors of the Hippo pathway, are emerging as important players in cancer biology and therapy response.

Decrease of 5-hydroxymethylcytosine and TET1 with nuclear exclusion of TET2 in small intestinal neuroendocrine tumors

BMC Cancer, 2018
Background Small intestinal neuroendocrine tumors (SI-NETs) originate from enterochromaffin cells scattered in the intestinal mucosa of the ileum and jejunum.

The Arabidopsis thaliana F-box gene HAWAIIAN SKIRT is a new player in the microRNA pathway. [PDF]

PLoS ONE, 2017
In Arabidopsis, the F-box HAWAIIAN SKIRT (HWS) protein is important for organ growth. Loss of function of HWS exhibits pleiotropic phenotypes including sepal fusion.

Intercompartmental communication in senescence

FEBS 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.

The challenges of purely mechanistic models in biology and the minimum need for a 'mechanism-plus-X' framework [PDF]

, 2018
Ever since the advent of molecular biology in the 1970s, mechanical models have become the dogma in the field, where a "true" understanding of any subject is equated to a mechanistic description. This has been to the detriment of the biomedical sciences,

Crosstalk between the actin cytoskeleton and Ran-mediated nuclear transport [PDF]

, 2005
Background Transport of macromolecules into and out of the nucleus is a highly regulated process. The RanGTP/RanGDP gradient controls the trafficking of molecules exceeding the diffusion limit of the nuclear pore across the nuclear envelope.

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

American 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 ...
