The detection of biomarkers in blood macrophages is a new non-invasive cancer screening method, but its performance in early stage lung cancer screening remains undetermined. We evaluated the Apo10 and TKTL1 levels in blood macrophages of 156 early-stage lung cancer patients and 153 controls.
Chemotherapy and targeted therapy are the major treatments for gastric cancer (GC), but drug resistance limits its effectiveness. Here, we profile the proteome of 206 tumor tissues from patients with GC undergoing either chemotherapy or anti-HER2-based therapy.
Accumulation of nucleotide building blocks prior to and during S phase facilitates DNA duplication. Herein, we find that the anaphase-promoting complex/cyclosome (APC/C) synchronizes ribose-5-phosphate levels and DNA synthesis during the cell cycle.
In the case of 16 patients, histone H3K27M mutation was confirmed by analysis of biopsy (n = 9) or liquid biopsy (n = 9) specimens. PDL1 mRNA expression was detected in circulating tumor cells of ten patients at diagnosis.
TKTL1: levels stable during chemotherapy and the induction of dendritic cell vaccines
High oncogenic risk human papillomaviruses (HR-HPVs) promote cervical carcinoma development, the fourth most common feminine cancer. A slow oncodevelopmental phase—defined histopathologically as Cervical Intraepithelial Neoplasia (CIN) grades 1–3, or cytologically as Low- or High-grade Squamous Intraepithelial Lesions (LSIL or HSIL)—precedes the malignancy.
Transketolase is a connecting link between glycolytic and pentose phosphate pathway, which is considered as the rate-limiting step due to synthesis of large number of ATP molecule and it can be proposed as a plausible target facilitating the growth of cancerous cells suggesting its potential role in cancer.
Transketolase-like 1 (TKTL1) plays an important role in the pentose phosphate pathway (PPP) branch. The main obstacle of ovarian cancer treatment is chemotherapeutic resistance. We investigated whether inhibiting TKTL1 in OC3/TAX300 cells could re-sensitize paclitaxel-resistant cells to paclitaxel and proposed a mechanism of action.
D-tagatose is a naturally existing rare monosaccharide having prebiotic properties. Minimal absorption, low metabolizing energy, and unique clinical properties are the characteristics of D-tagatose. D-tagatose gained international attention by matching the purpose of alternate sweeteners that is much needed for the control of diabetes among world population.
Oxygen free radicals are produced during stress, are unstable, and potentially interact with other cellular components or molecules. This reactivity can influence cellular function, including a prolongation in tissue recovery following exercise.
80 stomach adenocarcinoma patients (T1-3, NO, MO) were enrolled into a prospectively randomized clinical study. 40 patients were perioperatively treated with D-galactose (treatment group: 1.9 g/kg BW and per day) or D-glucose-containing electrolyte infusions (control group: n = 40).
Animal experiments in BALB/c-mice and in DBA/2-mice confirmed that lectin blockade with D-galactose containing receptor analogues can inhibit metastatic spread into the liver.
Dental plaque develops when early bacterial colonizers adhere to the acquired pellicle (saliva-derived proteinous coating on the tooth surface) followed by adhesion of late interspecies colonizers to form this type of biofilm (coaggregation).
The influence of different galactose concentrations on the cariogenic effect of Streptococcus mutans (strains: DSM 20381 and DSM 20523) in a sucrose diet (33%) was examined in an animal experiment. The treated Wistar rats were free of pathogenic germs at the beginning of the experiment.
Transketolase proteins or transketolase enzyme activities have been related to neurodegenerative diseases, diabetes, and cancer. Transketolase enzyme variants and reduced transketolase enzyme activities are present in patients with the neurodegenerative disease Wernicke-Korsakoff syndrome.
Cancer cells display high rates of aerobic glycolysis, a phenomenon known as the Warburg effect. Lactate and pyruvate, the end products of glycolysis, are overproduced by cancer cells even in the presence of oxygen.
This study aims to investigate the role of aberrant expression of TKTL1 (Transkelolase-like 1) in Head and Neck Squamous Cell Carcinoma (HNSCC) tumorigenesis and to characterize TKTL1 contribution to HNSCC tumorigenesis via aerobic glycolysis and HIF1α stabilization.
The EDIM-TKTL1 blood test was conducted in 240 patients with 17 different confirmed or suspected malignancies. Test scores were compared with (18)F-fluoro-2-deoxy-D-glucose (FDG)-PET/computed tomography (CT) results.
Biomarkers allowing the characterization of malignancy and therapy response of oral squamous cell carcinomas (OSCC) or other types of carcinomas are still outstanding.
Monocytes/macrophages are regarded as the first line of defense in tumors. Therefore, analyzing monocyte subtypes in oral squamous cell carcinoma (OSCC) may be of value in disease monitoring and to explore immunotherapeutic strategies for cancer patients.
Transketolase-like 1 (TKTL1) induces glucose degradation through anaerobic pathways, even in presence of oxygen, favoring the malignant aerobic glycolytic phenotype characteristic of tumor cells.
Epitope detection in monocytes (EDIM) represents a liquid biopsy exploiting the innate immune system. Activated monocytes (macrophages) phagocytose unwanted cells/cell fragments from the whole body including solid tissues.
The metabolism of cancer cells is often reprogrammed by dysregulation of metabolic enzymes. Transketolase-like 1 (TKTL1) is a homodimeric transketolase linking the pentose-phosphate pathway with the glycolytic pathway.
