Diacerein Disrupts Testicular Homeostasis: The Essential Role of Basal Cytokines in Maintaining Sertoli Cell Integrity and the Immune Microenvironment

Andrology, EarlyView.
ABSTRACT Background Pro‐inflammatory cytokines, TNF and IL‐1B, are essential for testicular homeostasis. Diacerein, an anti‐inflammatory drug, inhibits these cytokines, impairing M2 macrophages and Leydig cells (LCs). However, its impact on Sertoli cells (SCs) and M1 (CD68) macrophages remains unknown.

Multi‐omics analysis identifies a major histocompatibility complex class II‐associated antigen‐presenting cancer‐associated fibroblast‐like state linked to the nuclear factor erythroid 2‐related factor 2‐karyopherin subunit beta 1 axis in nonsmall cell lung cancer

Journal of Cell Communication and Signaling, Volume 20, Issue 2, June 2026.
NSCLC contains an MHC‐II‐associated antigen‐presenting CAF‐like (apCAF‐like) state regulated by the NRF2‐KPNB1 axis. NRF2/KPNB1 signaling suppresses CIITA‐dependent antigen presentation and T‐cell activation, whereas inhibition of this pathway enhances antitumor immunity and improves responsiveness to anti‐PD‐1 therapy.

Characterization of the mechanism of action of Transportin in mitotic spindle assembly [PDF]

, 2011
In eukaryotic cells, proteins known as karyopherins function during interphase as nuclear import and export receptors. Importin [beta] and Transportin, two such karyopherins, act to carry proteins with different recognition sites into the interphase ...

Structure and expression of Xenopus karyopherin-β3: definition of a novel synexpression group related to ribosome biogenesis

Mechanisms of Development, 2000
Karyopherin-beta3 is a nuclear transport receptor that appears to be involved in nuclear import of ribosomal proteins. Here we report on sequence and expression of karyopherin-beta3 in Xenopus. The differential distribution of karyopherin-beta3 mRNA during Xenopus embryogenesis is similar to that of several other protein import factors and of ribosomal

Promiscuous Binding of Karyopherin β 1 Modulates FG Nucleoporin Barrier Function and Expedites NTF2 Transport Kinetics [PDF]

Biophysical Journal, 2015
The transport channel of nuclear pore complexes (NPCs) contains a high density of intrinsically disordered proteins that are rich in phenylalanine-glycine (FG)-repeat motifs (FG Nups). The FG Nups interact promiscuously with various nuclear transport receptors (NTRs), such as karyopherins (Kaps), that mediate the trafficking of nucleocytoplasmic ...

Regulation of Immune Checkpoints: From Molecular Mechanisms to Clinical Therapies

MedComm, Volume 7, Issue 6, June 2026.
Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment by unleashing antitumor immunity. This review comprehensively examines the molecular mechanisms underlying key immune checkpoints—including PD‐1/PD‐L1, CTLA‐4, and TIM‐3—and their clinical applications.

Nucleus-specific importin alpha proteins and nucleoporins regulate protein import and nuclear division in the binucleate Tetrahymena thermophila

, 2008
The ciliate Tetrahymena thermophila, having both germ line micronuclei and somatic macronuclei, must possess a specialized nucleocytoplasmic transport system to import proteins into the correct nucleus.

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

Advanced Science, Volume 13, Issue 27, 13 May 2026.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

Targeting the nuclear export receptor exportin‐1 in acute myeloid leukaemia: From biology to clinical translation

Clinical and Translational Medicine, Volume 16, Issue 5, May 2026.
• XPO1 hyperactivation promotes leukaemogenesis by altering nucleocytoplasmic transport and transcriptional control in acute myeloid leukaemia (AML). • Selinexor and eltanexor show preferential activity in NPM1‐mutated, DEK::NUP214‐positive and SF3B1‐mutated myeloid neoplasms.
