GSE205035 Targeting CDK4/6 epigenetically impairs DNA damage repair to overcome the resistance to neoadjuvant chemotherapy in locally advanced rectal cancer
Contributors : Peng Deng ; Zhaoliang Yu ; Jing TanSeries Type : Expression profiling by high throughput sequencing ; Genome binding/occupancy profiling by high throughput sequencingOrganism : Homo sapiensResistance to neoadjuvant chemotherapy is associated tumor recurrence of locally advanced rectal cancer (LARC), which remains an unmet demand to exploit potential therapeutic strategies to improve clinical outcomes. Here we demonstrated that aberrant activation of cell cycle pathways is correlated with resistance to neoadjuvant chemotherapy in LARC. A combinatorial drug screening of 130 kinase inhibitors targeting cell ...

NeuroPredict: study of the predictive value of ABCB1 genetic polymorphisms and associated clinical factors in chronic chemotherapy-induced peripheral neuropathy (CIPN)
Conclusion: CIPN is a common and understudied toxicity, despite being a limiting factor in the quality of life of many patients. As described in acute CIPN, our study demonstrates the relationship between chronic neuropathy and being a carrier of specific polymorphisms (C1236T and C3435T) of the ABCB1 gene in patients treated with P. In addition, there are modifiable factors (obesity, smoking, or alcohol) that may influence its development. Further prospective studies are needed to investigate genetic and clinical modifiable factors predisposing to CIPPN to develop prevention and treatment strategies. (Source: Frontiers in Pharmacology)

Cancers, Vol. 16, Pages 946: Self-Completion Questionnaire on Sleep Evaluation in Patients Undergoing Oxaliplatin Therapy: An Observational Study
This study aims to understand the effects of sleep complaints on health and quality of life in cancer patients treated with oxaliplatin. A study has been conducted through the creation and distribution of questionnaires to patients to investigate their complaints about sleep quality. We observed significant differences between males and females in evaluating sleep hygiene scores, the Pittsburgh Sleep Quality Index, and previous difficulty sleeping. Moreover, in females, stress, worries, and anxiety seem to play a negative role in the sleep hygiene score. The obtained results could improve the interest of healthcare personn...

Efficacy of adding levofloxacin to gemcitabine and nanoparticle-albumin-binding paclitaxel combination therapy in patients with advanced pancreatic cancer: study protocol for a multicenter, randomized phase 2 trial (T-CORE2201)
This study will enroll patients treated with GEM/nabPTX as the first-line chemotherapy for stage IV pancreatic adenocarcinoma.DISCUSSION: GEM/nabPTX is a standard first-line chemotherapy regimen for patients with advanced pancreatic cancer. Recently, the superiority of 5-fluorouracil, liposomal irinotecan, and oxaliplatin combination therapy (NALIRIFOX) to GEM/nabPTX as first-line therapy for pancreatic cancer has been reported. However, the efficacy of NALIRIFOX is inadequate. Based on previous retrospective studies, it is hypothesized that treatment efficacy will improve when levofloxacin is added to GEM/nabPTX therapy. ...

The potential therapeutic effect of melatonin in oxaliplatin combination therapy against chemoresistant colorectal cancer cells
CONCLUSIONS: The results of cytotoxicity assays, MTT, and flow cytometry revealed that the combination of melatonin and oxaliplatin exerts synergistic effects on induction of oxaliplatin's cytotoxicity in CRC. Our research suggests that combining the treatments of melatonin and oxaliplatin may be considered as a new approach to overcoming oxaliplatin resistance in CRC patients.PMID:38401018 | DOI:10.1007/s11033-024-09316-9 (Source: Molecular Biology Reports)

Prediction for oxaliplatin ‐induced liver injury using patient‐derived liver organoids
ConclusionsThese results suggested that L-OHP-induced liver injury may be caused by mitochondrial oxidative damage. Furthermore, patient-derived liver organoids may be used to assess susceptibility to L-OHP-induced liver injury in individual patients. (Source: Cancer Medicine)

An Italian real-world multicenter study of patients with advanced mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) of the gastro-entero-pancreatic system treated with chemotherapy
ConclusionThis study confirms that GEP-MiNENs represent a complex disease and that over the past years the clinical management has been predominantly guided by the subjective judgment of the clinicians. Although, in this series, the NEC component appeared mostly responsible for the systemic spread and prognosis on the whole neoplasm, the lack of strong prognostic and predictive factors universally recognized seems to condition their management so far. Future prospective clinical and biomolecular studies could help clinicians to improve clinical management of GEP-MiNENs. (Source: Journal of Endocrinological Investigation)

Deciphering drug resistance in gastric cancer: Potential mechanisms and future perspectives
This article primarily explores the potential mechanisms of chemotherapy resistance in GC patients from five perspectives: cell death, tumor microenvironment, non-coding RNA, epigenetics, and epithelial-mesenchymal transition. Additionally, it proposes feasibility strategies to overcome drug resistance from four angles: cancer stem cells, tumor microenvironment, natural products, and combined therapy. The hope is that this article will provide guidance for researchers in the field and bring hope to more GC patients.PMID:38394851 | DOI:10.1016/j.biopha.2024.116310 (Source: Biomedicine and pharmacotherapy = Biomedecine and pharmacotherapie)

More than shots in the dark: improving patient stratification to move closer to personalised therapies in intrahepatic cholangiocarcinoma
Cholangiocarcinomas, the second most frequent hepatic tumour after hepatocellular carcinoma, make up around 2% of all gastrointestinal malignancies. It is believed that these tumours have been occurring more frequently recently, at least in Western countries, and that this is mostly due to an increase in intrahepatic cholangiocarcinoma (iCCA).1 The combination of cisplatin and gemcitabine was established as the first-line therapy for patients with advanced cholangiocarcinoma for several years based on the findings of the ABC-02 trial. Recently, the phase III TOPAZ-1 and KEYNOTE-966 studies found a survival benefit with dur...

Angew Chem Int Ed Engl. 2024 Feb 21:e202402291. doi: 10.1002/anie.202402291. Online ahead of print.ABSTRACTDeveloping combination chemotherapy systems with high drug loading efficiency at predetermined drug ratios to achieve a synergistic effect is important for cancer therapy. Herein, a polymeric dual-drug nanoparticle composed of a Pt(IV) prodrug derived from oxaliplatin and a mitochondria-targeting cytotoxic peptide is constructed through emulsion interfacial polymerization, which processes high drug loading efficiency and high biocompatibility. The depolymerization of polymeric dual-drug nanoparticle and the activation...
