The effects of Taxol on some immunological parameters were investigated, in vitro, in the murine macrophage cell line J774.1. Mitochondrial dehydrogenase activity and (3H) TdR incorporation were shown to be increased in Taxol treated cells. Likewise, Taxol induced TNF alpha secretion. But Taxol seemed to be a weak inducer of the two interleukins IL-1 and IL-2, since their detection occurred late in the cell culture supernatants.

Efficacy and Safety of Sirolimus-Coated Balloon Angioplasty in De Novo Lesions in Large Coronary Vessels: A Propensity Score-Matched Study.

Department of Cardio-Thoracic-Vascular Diseases, Foundation IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy.
Background: Evidence regarding drug-coated balloon (DCB)-only angioplasty in de novo lesions of large vessels is still limited and mainly focused on paclitaxel-coated balloon. We aimed to analyze the safety and efficacy of sirolimus-coated balloon (SCB)-only angioplasty in de novo lesions in large vessels compared to drug-eluting stent (DES).
Methods: In this retrospective, dual-center, case-control study, we enrolled all consecutive patients treated between January 2022 and January 2024 with SCB-only angioplasty in de novo lesion in large vessel (> 2.
KRAS Mutation Status and Treatment Outcomes in Patients With Metastatic Pancreatic Adenocarcinoma.
JAMA Netw Open

Huntsman Cancer Institute, University of Utah Health Care, Salt Lake City.
Importance: Despite the high prevalence of KRAS alterations in pancreatic ductal adenocarcinoma (PDAC), the clinical impact of common KRAS mutations with different cytotoxic regimens is unknown. This evidence is important to inform current treatment and provide a benchmark for emergent targeted KRAS therapies in metastatic PDAC.
Objective: To assess the clinical implications of common KRAS G12 mutations in PDAC and to compare outcomes of standard-of-care multiagent therapies across these common mutations.

Background: Uterine clear cell carcinoma (UCCC) is a rare and aggressive subtype of endometrial cancer, often presenting at an advanced stage with poor prognosis. Treatment options for advanced or recurrent UCCC are currently limited, especially after platinum-based chemotherapy has failed.
Case Presentation: We present the case of a 49-year-old female diagnosed with stage IV uterine clear cell carcinoma.
Inosine monophosphate dehydrogenase 2 (IMPDH2) modulates response to therapy and chemo-resistance in triple negative breast cancer.

Triple negative breast cancer (TNBC) is one of the deadliest subtypes of breast cancer, whose high frequency of relapse is often due to resistance to chemotherapy. Here, we identify inosine monophosphate dehydrogenase 2 (IMPDH2) as a contributor to doxorubicin resistance, in multiple TNBC models. Analysis of publicly available datasets reveals elevated IMPDH2 expression to associate with worse overall TNBC prognosis in the clinic, including lower recurrence-free survival post adjuvant/neoadjuvant therapy.

The effectiveness of paclitaxel (PTX) in treating non-small-cell lung carcinoma (NSCLC) is restricted by its poor pharmacokinetic profile and side effects. This limitation stems from the lack of a suitable delivery vector to efficiently target cancer cells. Therefore, there is a critical need to develop an efficient carrier for the optimised delivery of PTX in NSCLC therapy.
