Kinetics and Regulation Studies of the Production of
β-Galactosidase from Kluyveromyces marxianus Grown on Different Substrates

Food Technology and Biotechnology, 2003
Lactose-intolerance is manifested in 50 % of the world’s population. This can be remediated by removing lactose from the diet or converting it into glucose and galactose with
β-galactosidase (EC 3.2.1.23).

Strangers in a foreign land: 'Yeastizing' plant enzymes [PDF]

arXiv
Expressing plant metabolic pathways in microbial platforms is an efficient, cost-effective solution for producing many desired plant compounds. As eukaryotic organisms, yeasts are often the preferred platform. However, expression of plant enzymes in a yeast frequently leads to failure because the enzymes are poorly adapted to the foreign yeast cellular

Placental RTN3L‐dependent ER‐Phagy Contributes to Fetal Testicular Dysplasia Upon Environmental Stress

Advanced Science, EarlyView.
Gestational environmental stress activates ER‐phagy by increasing placental Rtn3l mRNA N6‐methyladenosine modification, further inhibiting placental estradiol synthesis and contributing to fetal testicular dysplasia. This study demonstrates the early prevention and treatment of adult male infertility from the perspective of fetal‐derived diseases ...

A novel luciferase‐based reporter tool to monitor the dynamics of carbon catabolite repression in filamentous fungi

Microbial Biotechnology
Filamentous fungi with their diverse inventory of carbohydrate‐active enzymes promise a holistic usage of lignocellulosic residues. A major challenge for application is the inherent repression of enzyme production by carbon catabolite repression (CCR ...

Plasma DNMT1 Activity for Assessing Tumor Burden and Predicting Neoadjuvant Therapy Response in Breast Cancer

Advanced Science, EarlyView.
In this work, a detection method is presented for the activity of plasma DNA methyltransferase 1 (DNMT1), namely DNMT1 Identification by Variable Activity (DIVA). DIVA can detect plasma DNMT1 at levels as low as 10−7 U mL−1, also it successfully evaluated tumor burden and predicted the neoadjuvant therapy responses of breast cancer patients.

HDAC6 and USP9X Control Glutamine Metabolism by Stabilizing GS to Promote Glioblastoma Tumorigenesis

Advanced Science, EarlyView.
Glioblastoma (GBM) growth relies on glutamine synthetase (GS), which is stabilized by histone deacetylase 6 (HDAC6) and deubiquitinated by ubiquitin‐specific peptidase 9, X‐linked (USP9X). HDAC6 promotes GS deacetylation, while USP9X removes its K48‐linked polyubiquitination, enhancing GS stability.

Inhibiting FAT1 Blocks Metabolic Bypass to Enhance Antitumor Efficacy of TCA Cycle Inhibition through Suppressing CPT1A‐Dependent Fatty Acid Oxidation

Advanced Science, EarlyView.
This study demonstrates that mutant FAT1 promotes ASCL2‐driven, CPT1A‐dependent fatty acid oxidation, leading to resistance to CPI‐613‐mediated TCA cycle inhibition in head and neck cancer. In vivo gene depletion of mutant FAT1 with LNP‐sgFAT1 suppresses tumor growth and restores CPI‐613 sensitivity, revealing a targetable metabolic bypass with ...
