Multifacet Roles of Cellular Senescence in Cancer: Mechanisms and Therapeutic Implications

MedComm – Oncology, Volume 5, Issue 1, March 2026.
Cellular senescence shapes tumor progression through both antitumor and protumor mechanisms. Senescence triggered by telomere shortening restricts malignant transformation and limits tumor cell proliferation, while the senescence‐associated secretory phenotype (SASP) secretion enhances antitumor immunity by activating cytotoxic T cells.

Mechanisms of Nuclear Export in Cancer and Resistance to Chemotherapy [PDF]

, 2016
YesTumour suppressor proteins, such as p53, BRCA1, and ABC, play key roles in preventing the development of a malignant phenotype, but those that function as transcriptional regulators need to enter the nucleus in order to function.

Targeting MCL‐1 and MAPK overcomes venetoclax resistance in FLT3‐ITD‐positive AML cells harbouring activating PTPN11 (SHP‐2) mutations

British Journal of Haematology, Volume 208, Issue 3, Page 905-915, March 2026.
Summary Venetoclax (VEN)‐based therapies have improved the treatment of acute myeloid leukaemia (AML); however, the emergence of resistance remains a major limitation. Mutations in protein tyrosine phosphatase (PTP) non‐receptor type 11 (PTPN11) and FMS like tyrosine kinase 3 with internal tandem duplication (FLT3‐ITD) are common in resistant patients ...

Preclinical activity of selinexor, an inhibitor of XPO1, in sarcoma

Oncotarget, 2016
Selinexor is an orally bioavailable selective inhibitor of nuclear export that has been demonstrated to have preclinical activity in various cancer types and that is currently in Phase I and II clinical trials for advanced cancers. In this study, we evaluated the effects of selinexor in several preclinical models of various sarcoma subtypes.

EIF1AX Nucleolar Condensates Enhance Susceptibilities for the Management of Endometrial Cancer

Advanced Science, Volume 13, Issue 12, 27 February 2026.
This schematic illustrates the mechanism of a senolytic strategy in endometrial cancer. EIF1AX facilitates the incorporation of DDX21 into nucleolar condensates, an event that suppresses rDNA transcription and induces cellular senescence. The compound 2,5‐MeC exploits this pathway by promoting EIF1AX nucleolar translocation and condensate formation ...

Specific inhibition of the nuclear exporter exportin-1 attenuates kidney cancer growth.

PLoS ONE, 2014
PurposeDespite the advent of FDA-approved therapeutics to a limited number of available targets (kinases and mTOR), PFS of kidney cancer (RCC) has been extended only one to two years due to the development of drug resistance.

XPO1 Inhibition enhances sensitivity to platinum-based chemotherapy in germinal-center B-cell-like-DLBCL cells

Hematology
Purpose: Platinum-based chemotherapy is considered as salvage therapy to relapsed/refractory diffuse large B-cell lymphoma (DLBCL) patients. However, treatment failure due to drug resistance occurs in some patients, particularly those with Exportin 1 ...

XPO1 blockade with KPT-330 promotes apoptosis in cutaneous T-cell lymphoma by activating the p53–p21 and p27 pathways

Scientific Reports
Dysregulated nuclear-cytoplasmic trafficking has been shown to play a role in oncogenesis in several types of solid tumors and hematological malignancies. Exportin 1 (XPO1) is responsible for the nuclear export of several proteins and RNA species, mainly

Effect of Exportin 1/XPO1 Nuclear Export Pathway Inhibition on Coronavirus Replication

Viruses
The nucleocytoplasmic transport of proteins using XPO1 (exportin 1) plays a vital role in cell proliferation and survival. Many viruses also exploit this pathway to promote infection and replication.

Novel small molecule XPO1/CRM1 inhibitors induce nuclear accumulation of TP53, phosphorylated MAPK and apoptosis in human melanoma cells.

PLoS ONE, 2014
XPO1/CRM1 is a key nuclear exporter protein that mediates translocation of numerous cellular regulatory proteins. We investigated whether XPO1 is a potential therapeutic target in melanoma using novel selective inhibitors of nuclear export (SINE).
