Gut microbiota diversity is prognostic and associated with benefit from chemo‐immunotherapy in metastatic triple‐negative breast cancer

open access: yesMolecular Oncology, Volume 19, Issue 4, Page 1229-1243, April 2025.
We assessed the associations between the gut microbiota and outcome in metastatic triple‐negative breast cancer patients treated with chemotherapy alone or chemotherapy in combination with immunotherapy. Our data indicate that high gut microbiota alpha diversity was associated with improved clinical outcome and with benefit from immunotherapy.

Vertical inhibition of p110α/AKT and N‐cadherin enhances treatment efficacy in PIK3CA‐aberrated ovarian cancer cells

open access: yesMolecular Oncology, Volume 19, Issue 4, Page 1132-1154, April 2025.
PIK3CA amplification and PIK3CA mutation enhance ovarian tumorigenicity through an activation of AKT, which phosphorylates YAP at Ser127. This Ser127 phosphorylation leads to the retention of YAP in the cytoplasm and triggers RAC1 activity, promoting cell migration. Additionally, AKT activation increases expression of N‐cadherin, which further enhances

Crosstalk between gut microbiota and tumor: tumors could cause gut dysbiosis and metabolic imbalance

open access: yesMolecular Oncology, EarlyView.
In this research, we analyzed the relationship between gut microbiota and tumor. We discovered that both subcutaneous and metastatic tumors would alter the composition and metabolic function of gut microbiota. Meanwhile, fecal microbiota transplantation also indicated the anti‐tumor role of the gut microbiota, revealing the crosstalk between tumor and ...

Integrative analysis of circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients: a comprehensive approach

open access: yesMolecular Oncology, EarlyView.
This study simultaneously investigated circulating tumor cells (CTCs) and exosomes from small‐cell lung cancer (SCLC) patients. The elevated expression of JUNB and CXCR4 in CTCs was a poor prognostic factor for SCLC patients, whereas exosomal overexpression of these biomarkers revealed a high discrimination ability of patients from healthy individuals,

The accumulation of myeloid‐derived suppressor cells participates in abdominal infection‐induced tumor progression through the PD‐L1/PD‐1 axis

open access: yesMolecular Oncology, Volume 19, Issue 5, Page 1532-1545, May 2025.
This study explores how sepsis affects GC progression by creating an immunosuppressive environment. Our findings reveal that sepsis promotes immune dysregulation, enhancing tumor growth and metastasis. Targeting the PD‐1/PD‐L1 pathway with monoclonal antibodies shows potential for restoring immune function and improving outcomes in cancer patients ...

Plasma‐activated media selectively induces apoptotic death via an orchestrated oxidative stress pathway in high‐grade serous ovarian cancer cells

open access: yesMolecular Oncology, Volume 19, Issue 4, Page 1170-1187, April 2025.
High‐grade serous ovarian cancer (HGSOC) is the most common and aggressive type of ovarian cancer with urgent need for new treatment strategies. This study evaluates plasma‐activated media (PAM) as a novel treatment for HGSOC, showing its ability to selectively induce oxidative stress and apoptosis in HGSOC cell lines, patient ascites cells and primary

Loss of SETD2 in wild‐type VHL clear cell renal cell carcinoma sensitizes cells to STF‐62247 and leads to DNA damage, cell cycle arrest, and cell death characteristic of pyroptosis

open access: yesMolecular Oncology, Volume 19, Issue 4, Page 1244-1264, April 2025.
Vulnerability to the small molecule STF‐62247 is observed in SETD2‐inactivated VHL‐positive clear cell renal cell carcinoma (ccRCC) cells. DNA damage and loss of CDC25A leads to cell cycle arrest in S phase. Cleavage of caspase‐3 (CASP3) and gasdermin E (GSDME) suggests cell death by pyroptosis.

Unraveling epigenetic heterogeneity across gastrointestinal adenocarcinomas through a standardized analytical framework

open access: yesMolecular Oncology, Volume 19, Issue 4, Page 1117-1131, April 2025.
This study shows that patients with gastrointestinal adenocarcinomas can be stratified into six distinct subtypes based on genome‐scale DNA methylation profiling. This stratification, achieved using a robust analytical framework, aligns with established tumor characteristics and holds potential to support prognostication.

The CDK12–BRCA1 signaling axis mediates dinaciclib‐associated radiosensitivity through p53‐mediated cellular senescence

open access: yesMolecular Oncology, Volume 19, Issue 4, Page 1265-1280, April 2025.
Dinaciclib blocks CDK12 activity, leading to downregulation of BRCA1, and probably other proteins involved in homologous recombination, promoting nonhomologous end joining. In this scenario, the presence of ionising radiation triggers a p53‐dependent senescent response that yields increased radiosensitivity. Pan‐cyclin‐dependent‐kinase (CDK) inhibitors
