Unraveling the epigenetic code in cancer cell–tumor microenvironment crosstalk

open access: yesMolecular Oncology, EarlyView.
Epigenetic regulation is a key driver of cancer development and progression. Diverse epigenetic alterations in cancer cells and components of the tumor microenvironment (TME) orchestrate their communication through multiple mechanisms. We discuss how the epigenetic code coordinates bidirectional cancer cell–TME crosstalk to promote cancer progression ...

Purification of yeast isocitrate dehydrogenase [PDF]

open access: yesBiochemical Journal, 1972
The NAD-linked isocitrate dehydrogenase from baker's yeast was purified to homogeneity (as judged by gel filtration and polyacrylamide-gel electrophoresis) with an overall yield of 50% by using dilute solutions of the allosteric effector (AMP) to elute the enzyme specifically from CM-cellulose.

APOBEC3 activity and DNA polymerase‐ε deficiency are associated with distinct IDH1 R132 hotspot mutations

open access: yesMolecular Oncology, EarlyView.
Isocitrate dehydrogenase 1 (IDH1) mutations are highly recurrent in multiple human cancer types, including cholangiocarcinoma and glioma. IDH1 R132C is the most common IDH1 mutation in cholangiocarcinoma and likely arises from APOBEC3A‐ or APOBEC3B‐mediated deamination.

Clinical Impact of MGMT Promoter Methylation in IDH‐Mutant Gliomas: Influence of Threshold Selection and Clinical Confounding

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background The clinical relevance of MGMT promoter methylation in IDH‐mutant gliomas remains controversial in the era of molecular classification. We aimed to systematically evaluate its clinical relevance by integrating quantitative assessment, cutoff exploration, and adjustment for clinical confounding.

Biocatalytic Isocitrate Production from Low‐Concentration Gaseous CO2 and Biobased 2‐Oxogultarate

open access: yesAdvanced Energy & Sustainability Research
Isocitrate dehydrogenase (IDH) from yeast (EC 1.1.1.42) is an enzyme that catalyzes the decarboxylating isocitrate into 2‐oxogurtarate and carbon dioxide and the reverse process of the introducing carbon dioxide as a carboxy‐group to 2‐oxogurtarate to ...

Novel protein acetyltransferase, Rv2170, modulates carbon and energy metabolism in Mycobacterium tuberculosis

open access: yesScientific Reports, 2017
Recent data indicate that the metabolism of Mycobacterium tuberculosis (Mtb) inside its host cell is heavily dependent on cholesterol and fatty acids. Mtb exhibits a unique capacity to co-metabolize different carbon sources and the products from these ...

Effects of Nitrogen Deficiency on the Metabolism of Organic Acids and Amino Acids in Oryza sativa

open access: yesPlants, 2022
Organic acids metabolism and nitrogen (N) metabolism in rice seedlings and the relationship between them are not fully understood. In this study, rice (Oryza sativa L. ssp. Indica) variety “Huanghuazhan” was used as the experimental material, and three N

Advanced Materials for Biologics Delivery to Brain Tumors

open access: yesAdvanced Materials, EarlyView.
Material innovation is central to unlocking the therapeutic potential of biologics against many central nervous system diseases, including brain cancer. By engineering carriers with controlled transport, targeting, and release properties, advanced materials can overcome the blood–brain barrier and tumor microenvironment, improving the delivery of ...

Studies on activities of PTA, AK, ICL and MS enzymes involved in the acetate metabolism of Corynebacterium glutamicum

open access: yes浙江大学学报. 农业与生命科学版, 2003
The four enzymes of acetate kinase (AK), phosphotransacetylase (PTA), isocitrate lyase (ICL) and malate systhase (MS) which are involved in the acetate metabolism of Corynebacterium glutamicum have been developed in their assay methods.

Integrative Omics Analysis Reveals the Regulation of Hypoxia Tolerance in Large Yellow Croaker (Larimichthys crocea) via the Lipoic Acid Synthase (lias) Gene

open access: yesAdvanced Science, EarlyView.
Lipoic acid synthase (lias) can regulate α‐KG levels through lipoylation, thereby negatively regulating HIF‐1α protein levels via PHD under hypoixa. The Hap2 allele of lias exhibits lower expression levels than Hap1, leading to the accumulation of more HIF‐1α protein and thereby enhancing hypoxia tolerance. ABSTRACT Hypoxia stress seriously affects the
