A novel mouse model simulating C5 palsy after cervical surgery

Animal Models and Experimental Medicine, EarlyView.
This study establishes a reliable mouse model of permanent C5 palsy (post‐laminectomy complication) via dorsal approach, selectively severing the C5 anterior nerve root while preserving the posterior root through partial C4 and C5 laminectomy. The model successfully replicates clinical C5P features—flaccid shoulder paralysis, electrophysiological ...

Hyperacetylated histone H4 is a source of carbon contributing to lipid synthesis

The EMBO Journal
Histone modifications commonly integrate environmental cues with cellular metabolic outputs by affecting gene expression. However, chromatin modifications such as acetylation do not always correlate with transcription, pointing towards an alternative ...

GCN5 potentiates Hepatocellular Carcinoma by Promoting SRC3 gene expression [PDF]

, 2015
摘要 组蛋白乙酰化在转录调节过程中起着重要的作用，它可以使染色体处于一种活化的状态。在细胞中，维持组蛋白的乙酰化和去乙酰化之间的平衡是通过组蛋白乙酰转移酶（HATs）和组蛋白去乙酰化酶（HDACs）这二者间的平衡实现的。如果这二者间的平衡被打破了，那么基因的乙酰化水平就改变了，从而可能诱发癌症。虽然HDACs抑制剂可以有效的预防和治疗癌症，但是一些抑制剂会激活一些非靶基因从而使人出现抗药性。为了确保乙酰化和去乙酰化之间的完全平衡以及掌握在癌症中HATs在组蛋白乙酰化过程中特定的功能 ...

Compensation Response to Hepatic Gluconeogenesis via β‐Hydroxybutyrylation of FBP1 and PCK1 in Dairy Cows

Animal Research and One Health, EarlyView.
(1) Kbhb modification of FBP1 and PCK1 is involved in regulation of the gluconeogenesis pathway. (2) Kbhb of FBP1 and PCK1 is catalyzed by p300 and removed by HDACs. (3) BHB induced an increase in the enzymatic activity of FBP1 and PCK1 through Kbhb modification at the K43 site of FBP1 and the K191 site of PCK1.

Exploring the Roles of Tuna‐Associated Acinetobacter sp. YFT067: Implications for Host Health and Metabolism

Animal Research and One Health, EarlyView.
This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...

Endogenous melatonin partial metabolic clearance as a potential endogenous marker of CYP1A2 activity

British Journal of Clinical Pharmacology, EarlyView.
Aims Cytochrome P450 1A2 (CYP1A2) exhibits substantial interindividual variability, necessitating appropriate phenotyping strategies for personalized pharmacotherapy. This study evaluated endogenous melatonin partial metabolic clearance (CLm(MEL)), calculated from urinary 6‐hydroxymelatonin (6‐O‐MEL) excretion and plasma melatonin (MEL) exposure, as a ...

Engineering of CoA‐Acylating Butyraldehyde Dehydrogenase for Enhanced 1,3‐Butanediol Production in Escherichia coli

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Microbial production of 1,3‐butanediol (1,3‐BDO) offers a renewable route to this versatile C4 chemical. However, the low performance of CoA‐acylating butyraldehyde dehydrogenase (Bld), which contains a catalytic cysteine, limits efficient production in recombinant Escherichia coli (E. coli).

Genetically Programmed Control of Overflow Metabolism

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Overflow metabolism is a highly undesirable phenomenon that occurs in virtually all cell factories. Although several schemes have been applied to avoid overflow metabolism, this problem remains far from being solved. In this study, a genetic sensor for detecting overflow metabolism was designed, and its substrate specificity and reversibility ...

Genetic code expansion for chemosensing and chemical actuation of biological functions

Bulletin of the Korean Chemical Society, EarlyView.
Genetic code expansion (GCE) broadens the chemical repertoire for precise control of protein function in biological systems. This review highlights GCE‐based sensing and actuating systems that operate through selective interactions between noncanonical amino acids and chemical triggers.
