Metabolomic Signatures of Relapse and Survival in AML Patients Receiving Allogeneic Hematopoietic Stem Cell Transplantation.
: Allogeneic stem cell transplantation (HSCT) is curative in acute myeloid leukemia (AML) but is limited by relapse and non-relapse mortality (NRM). Metabolomic prognostic value is unclear. We assessed whether plasma metabolite profiles at …

Identification of Human Transferrin Receptor as an Entry Co-receptor for Parvovirus B19 Infection of Human Erythroid Progenitor Cells.
[UNLABELLED] Parvovirus B19 (B19V), a member of the genus within the family, infects human erythroid progenitor cells (EPCs) of bone marrow and fetal liver, and causes various hematological disorders. The minor capsid protein VP1 of B19V …

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration-resistant prostate cancer.
Prostate cancer (PCa) is the second leading cause of cancer-related death among men in the United States. While organ-confined disease has a reasonable expectation of cure, metastatic PCa is universally fatal upon recurrence during hormone …

Integrative network pharmacology and machine learning identify potential targets of indole-3-lactic acid in colorectal cancer.
The treatment of colorectal cancer (CRC) remains challenging due to chemotherapy resistance and genetic heterogeneity. Indole-3-lactic acid (ILA), a tryptophan metabolite derived from gut microbiota, exhibits promising anti-inflammatory and…

Interplay of oxidative stress and antioxidant mechanisms in cancer development and progression.
Cellular systems responsible for the formation and removal of reactive oxygen species (ROS), functioning within physiological limits, are essential for maintaining intracellular redox balance. This state is known as oxidative eustress. Key …

L-ascorbate prevents non-alcoholic steatohepatitis-based hepatocarcinogenesis in Sod1/Prdx4 double-knockout mice.
Superoxide dismutase 1 (Sod1) and peroxiredoxin 4 (Prdx4) double knockout (DKO) causes symptoms similar to non-alcoholic steatohepatitis (NASH) even at younger ages. This study revealed that DKO mice exhibited high mortality, and surviving …

Updated bowel preparation regimens for colonoscopy: benefits and drawbacks.
Optimal bowel preparation is critical for high-quality colonoscopy and the effective prevention of colorectal cancer. Although traditional high-volume polyethylene glycol (PEG) electrolyte lavage solutions are effective and safe, they are f…

Iron-oxide nanoparticles selectively enhance the toxicity of pharmacological ascorbate through hydrogen peroxide-dependent DNA damage in non-small cell lung cancer (NSCLC).
Pharmacological ascorbate (IV delivery, to plasma levels ≈ 15-20 mM) has been shown to be selectively toxic to cancer vs. normal cells as well as inducing radio-chemo-sensitization in non-small cell lung cancer (NSCLC) via increased generat…

Phase IB trial of high dose ascorbic acid + nab-paclitaxel + cisplatin + gemcitabine in patients with untreated metastatic pancreatic cancer.
[BACKGROUND] Preclinical studies suggest that cancer cells take up oxidized vitamin C (dehydroascorbate, DHA) via the GLUT1 transporter, leading to oxidative stress and glutathione depletion. This mechanism may offer a therapeutic strategy …

Optimization of the radiosynthesis of the PSMA-targeting drugs [Lu]Lu-P17-087 and [Lu]Lu-P17-088 on the MiniLu™ automated module.
[BACKGROUND] There is a renewed interest in radioligand therapy for cancer treatment since the approval of Lu-177 vipivotide tetraxetan (PSMA-617) by regulators in Europe and the United States for metastatic castrate resistant prostate canc…

A charge reversal nanomedicine based on dual pH-responsive crosslinked dextran-based polysaccharide for synergistic cancer chemo/chemodynamic therapy.
The clinical use of chemotherapy alone has been restricted by its unsatisfactory curative effects and serious adverse effects. Chemotherapy combined with chemodynamic therapy (CDT) has recently emerged as an effective strategy for pancreati…

Integration of single-cell and bulk RNA sequencing data to identify liquid-liquid phase separation-related prognostic biomarkers in hepatocellular carcinoma.
Liquid-liquid phase separation (LLPS) has been linked to the initiation and progression of cancers. This study aimed to investigate the LLPS-related molecular features and develop a prognostic signature for hepatocellular carcinoma (HCC). S…

Genotoxic effects of aristolochic acid I on functional human-induced hepatocyte-like cells.
Aristolochic acid I (AAI) is a carcinogen associated with various human cancers. However, its causal relationship with hepatocellular carcinoma remains controversial, and inconsistent results from rodent studies have suggested species-speci…

High-dose vitamin C as a targeted treatment for KRAS-driven cancers?
KRAS mutations are frequently observed in human cancer and are associated with proliferation, therapy-resistance and worse outcome. Regrettably, only a fraction of possible mutations is druggable. Therefore, a tailored and possibly cost-eff…

Transcriptomics assisted by metabolomics analysis provides insights into regulation mechanisms during carcinogenic process in a hydrodynamically transfected liver cancer model.
[BACKGROUND] Hepatocellular carcinoma (HCC) ranks among the most prevalent malignancies with a substantial mortality rate, and its pathogenesis is relatively complex. Animal models provide valuable tools for exploring the causes and mechani…

Relationship Between Prostate Cancer and Benign Hyperplasia: Role of Inflammation-Induced Oxidative Stress, Vitamin C, and Epigenetics.
Benign prostatic hyperplasia and prostate cancer (PC) frequently affect aging men, both involving irregular cell growth in the prostate. Inflammation is a major contributor to these conditions, whereas DNA methylation and hydroxymethylation…

Pharmacologic ascorbate resistant pancreatic cancer demonstrates enhanced metastatic potential.
Pharmacological ascorbate (P-AscH, high-dose, intravenous, vitamin C), is a pro-drug that generates hydrogen peroxide (HO) and is being investigated as a neoadjuvant treatment for pancreatic adenocarcinoma (PDAC). In a randomized, phase II …

Non-invasive diagnosis of papillary thyroid microcarcinoma using a novel metabolomics analysis of urine.
[BACKGROUND] The severity of thyroid cancer is judged on the basis of histologic and clinical features. A limited number of studies have considered urinary metabolite signatures for its diagnosis, and no reliable urinary metabolite biomarke…
