概括
糖尿病病 (DKD) 涉及较低的Nrf2抗氧化剂水平和较高的Keap1抑制剂水平. 在DKD中,MicroRNA 30e-5p也降低,影响功能.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 分子生物学分子生物学
- 遗传学 是一个遗传学.
背景情况:
- 糖尿病病 (DKD) 是全球慢性病 (CKD) 的主要原因之一.
- 氧化应激与DKD病变发生有关.
- 抗氧化核因子红色素2相关因子2 (Nrf2) 和其调节剂在人类DKD中的作用尚未得到充分研究.
研究的目的:
- 调查Nrf2及其抑制剂Keap1及其特定微RNA (miRNA) 在2型糖尿病和DKD患者中的作用.
- 分析基因表达水平及其与脏健康指标的相关性.
主要方法:
- 病例控制研究涉及99名参与者:33人患有DKD,33人患有2型糖尿病而没有DKD,33人为对照组.
- 对Nrf2,Keap1和六种miRNA的信使RNA (mRNA) 水平的量化.

01:11Renal Failure: Dose Adjustments
88
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.

7.4K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

01:31Transducer Mechanism: Nuclear Receptors
1.3K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
