Androgen deprivation therapy (ADT) is a mainstay of treatment for prostate cancer (PCa). As androgens stimulate erythropoiesis, ADT is associated with a reduction in hematocrit, which in turn contributes to fatigue and related morbidity. However, the mechanisms involved in ADT-induced reduction in erythropoiesis remain unclear. We conducted a 6-month prospective cohort study and enrolled men with PCa about to undergo ADT (ADT-Group) and a control group of men who had previously undergone prostatectomy for localized PCa and were in remission (Non-ADT Group)...

Several nanomaterials rely on the passive accumulation in the neoplasm target because of enhanced permeability and retention effect. On the other hand, directing nanomaterials to the target by employing the targeting agents may lead to a pivotal improvement in the efficacy of the treatment for a number of cancers. However, targeting moieties often lose their functionality upon injection in the bloodstream, leaving questions on their efficiency. Here, we assessed using a significant in vitro 3D model of pancreatic carcinoma the targeting efficiency of passion fruit-like nanoarchitectures (NAs) incorporated with a peptide that can recognize transferrin directly in the medium, thereby modulating protein solvation...

Cancer is the primary cause of human mortality in most countries. This tendency has increased as various medical therapeutics have advanced, which suggests that we cannot escape carcinogenesis, although the final outcome may be modified by exposomes and statistics. Cancer is classified by its cellular differentiation. Mesothelial cells are distinct in that they line somatic cavities, facilitating the smooth movement of organs, but are not exposed to the external environment. Malignant mesothelioma, or simply mesothelioma, develops either in the pleural, peritoneal or pericardial cavities, or in the tunica vaginalis testes...

The tumor-promoting functions of neutrophils have been mainly attributed to induction of tumor angiogenesis or suppression of anticancer immunity. However, a direct impact of neutrophils on tumor cell growth and metastasis remains largely uncharacterized. Here, we coupled a proteomic approach with a functional screen to interrogate the secretome of tumor-associated neutrophils. Surprisingly, the iron-transporting protein transferrin was identified as the major mitogen for tumor cells secreted by neutrophils...

Objective: Fecal transferrin has been suggested as a complementary or even superior marker for early detection of colorectal cancer (CRC) besides fecal hemoglobin. We aimed to evaluate both markers individually and in combination in a large cohort of participants of screening colonoscopy. Methods: Precolonoscopy stool samples were obtained from participants of screening colonoscopy and frozen at -80℃ until blinded analysis, using a dual-quantitative fecal immunochemical test (FIT) for hemoglobin and transferrin...

OBJECTIVES: Gastrointestinal microflora is involved in the development and regulation of the immune response. Non-pathogenic bacteria are important to prevent the development and subsequent invasion of enteropathogenic bacteria. Surgical trauma and intestinal preparation can disrupt the intestinal microbiota balance. Modulating the microbiota in the preoperative period in patients with colorectal cancer may have an effect on the occurrence of postoperative complications. The aim of this study was to assess the effect of preoperative synbiotic administration in patients with colorectal cancer subjected to colorectal resection...

Anemia in cancer patients is quite common, with remarkable negative impacts on quality of life and overall prognosis. The pathogenesis is complex and typically multifactorial, with iron deficiency (ID) often being a major and potentially treatable contributor. In turn, ID in cancer patients can be due to multiple concurring mechanisms, including bleeding (e.g., in gastrointestinal cancers or after surgery), malnutrition, medications, and hepcidin-driven iron sequestration into macrophages with subsequent iron-restricted erythropoiesis...

Photodynamic therapy (PDT) is a non-invasive phototherapy that has gained significant attention for cancer therapy. However, image-guided PDT still remains a considerable challenge. Herein, we developed a targeted, near-infrared (NIR) fluorescence imaging nanoprobe for cancer cells by preparing natural biomass carbon dots (NBCDs) from lychee exocarp, and loading transferrin and a photosensitizer on the NBCD surfaces for image-guided PDT of cancer cells and mouse tumors. Because the surfaces of cancer cells exhibit more transferrin receptors, the proposed NIR fluorescent nanoprobe can better penetrate cancer cells for cancer cell targetable fluorescence imaging...

BACKGROUND: Site-specific multimodal nanoplatforms with fluorescent-magnetic properties have great potential for biological sciences. For this reason, we developed a multimodal nanoprobe (BNPs-Tf), by covalently conjugating an optical-magnetically active bimodal nanosystem, based on quantum dots and iron oxide nanoparticles, with the human holo-transferrin (Tf). METHODS: The Tf bioconjugation efficiency was evaluated by the fluorescence microplate assay (FMA) and the amount of Tf immobilized on BNPs was quantified by fluorescence spectroscopy...

Size-exclusion chromatography-inductively coupled plasma-mass spectrometry (SEC-ICP-MS) was used to study the serum-binding preferences of two metallodrugs with anticancer activities in vivo, namely the organoruthenium compound plecstatin-1 and its isosteric osmium analog. The complexes were administered intraperitoneally into mice bearing a CT-26 tumor. Comparing the total metal content of mouse whole blood and serum underlined that the metallodrugs are mainly located in serum and not in the cellular fraction of the blood samples...

PURPOSE: Pancreatic ductal adenocarcinoma (PDAC) is one of the most deadly cancers with a 5-year survival rate of less than 10%. Physicians often rely on biopsy or CT to guide treatment decisions, but these techniques fail to reliably measure the actions of therapeutic agents in PDAC. KRAS mutations are present in >90% of PDAC and are connected to many signaling pathways through its oncogenic cascade, including extracellular regulated kinase (ERK) and MYC. A key downstream event of MYC is transferrin receptor (TfR), which has been identified as a biomarker for cancer therapeutics and imaging...

Purpose: The prevalence of anemia ranges between 30% and 90% in cancer patients, affecting the health status, quality of life, and treatment outcome. Therefore, a proper diagnosis and management of anemia is crucial in these patients. Iron deficiency is diagnosed in~32%-60% of the cases. In this observational study, we evaluated the efficacy and safety of intravenous iron (ferric carboxymaltose [FCM], Ferinject® ) in the treatment of iron-deficiency anemia in patients with gastrointestinal tumors undergoing palliative or adjuvant chemotherapy...

A role of pro- and antioxidants for reducing rectal cancer (RC) incidence in operative, preoperative, and postoperative treatments is still disputable and controversial. The redox state of venous blood and tissues of blood vessels of 60 patients with RC (T2-4 N0-2 M0 G2 ) and 20 donors is studied by means of the conventional and spin-trapping electron paramagnetic resonance (EPR). The intensity of the signals from ceruloplasmin (CP), transferrin (TF), and labile iron pool (LIP) at temperature T = 77 K as well as superoxide generation rate and nitric oxide (NO) levels at T = 300 K is measured...
