Topology‐Aware Deep Learning on Higher‐Order Structures for Drug Response Prediction

Advanced Science, EarlyView.
We present TopDr, a topology‐aware deep learning framework that encodes both drugs and cell lines as multiscale simplicial complexes, capturing interactions at the 0‐, 1‐, and 2‐simplex levels. By jointly integrating local higher‐order neighborhoods and global topological structures, TopDr generates enriched representations for sensitivity prediction ...

Sex‐Based Body Composition Changes in Patients With Rectal Cancer Undergoing Preoperative Chemoradiotherapy: A Prospective Observational Study

Annals of Gastroenterological Surgery, EarlyView.
This prospective study observed that preoperative chemoradiotherapy for rectal cancer was associated with reductions in body fat and grip strength, which appeared to be more pronounced in female patients. These findings suggest that sex‐sensitive nutritional and exercise support may be beneficial to help maintain muscle mass and physical function ...

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

The Protective Effect of Ethanolic Extract of Mentha spicata Against Irinotecan-Induced Mucositis in mice

Iraqi Journal of Pharmaceutical Sciences, 2019
Irinotecan induced-mucositis is an inflammatory event of intestine caused by an increase in concentration of active metabolite 7­ethyl­10-hydroxycamptothecin (SN­38) in the intestine. Irinotecan must first be converted by a carboxylesterase (CES) to the

ATM kinase inhibitor AZD0156 in combination with irinotecan and 5-fluorouracil in preclinical models of colorectal cancer

BMC Cancer, 2022
Background AZD0156 is an oral inhibitor of ATM, a serine threonine kinase that plays a key role in DNA damage response (DDR) associated with double-strand breaks.

Risk factors for irinotecan-induced liver injury: a retrospective multicentre cross-sectional study in China

BMJ Open, 2023
Objectives The hepatotoxicity of irinotecan has been widely implicated in the treatment of multiple solid tumours. However, there are few studies on the influencing factors of irinotecan-induced hepatotoxicity.

Mesoporous Silica Nanoparticles With Customized Drug Ratio/Loading for Effective Treatment of Gemcitabine‐Resistant Pancreatic Tumors

Advanced NanoBiomed Research, EarlyView.
Redox responsive mesoporous silica nanoparticles (MSNs) were engineered to deliver gemcitabine (Gem) and cisplatin (cisPt) at defined ratios to overcome chemoresistance in pancreatic ductal adenocarcinoma (PDAC). Optimized Gem MSNs and Gem cisPt MSNs enhanced cytotoxicity in murine and human Gem resistant models, with select formulations inducing ...

Bi-weekly irinotecan is an effective and convenient regimen in the treatment of relapsed or refractory small cell lung cancer

BMC Cancer
Background Despite initial dramatic responses, metastatic small cell lung cancer (SCLC) invariably recurs. Irinotecan is one of the active agents for patients with recurrent SCLC.

P-glycoprotein-dependent pharmacokinetics of irinotecan and its active metabolite, SN-38 in rats: Effect of verapamil

ADMET and DMPK, 2015
We have recently demonstrated that the oral bioavailability of irinotecan (80 mg/kg) can be increased at least 7-fold by co-administration of the P-gp blocker verapamil (25 mg/kg, Oral).
