Novel roles of ER stress in repressing neural activity and seizures through Mdm2- and p53-dependent protein translation.

PLoS Genetics, 2019
Seizures can induce endoplasmic reticulum (ER) stress, and sustained ER stress contributes to neuronal death after epileptic seizures. Despite the recent debate on whether inhibiting ER stress can reduce neuronal death after seizures, whether and how ER ...

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Endoplasmic reticulum stress and oxidative imbalance is the missing link in fibromyalgia pathophysiology

Scientific Reports
Fibromyalgia syndrome (FMS) is a chronic pain disorder characterized by widespread musculoskeletal pain, fatigue, and cognitive dysfunction. Although its exact pathophysiology remains unclear, emerging evidence suggests that endoplasmic reticulum (ER ...

Obesity and ER Stress

The Korean Journal of Obesity, 2011
비만은 비정상적인 또는 과다한 지방의 축적에 따른 건 강의 위협상태로 정의된다. 이미 전 세계적으로 5번째로 많 은 사망요인으로 보고된 비만에 의해 매년 적어도 280만명 이상의 성인이 사망한다. 세계보건기구 (WHO)의 2008년도 보고서에 따르면, 전 세계적으로 약 15억의 성인이 과체중 을 보이며, 그 중 5억명이 비만인구로 분류된다. 이와 같은 비만은 특히 고지방, 고염류, 고탄수화물의 음식 섭취와 도 시화에 따른 운동부족에 따른 섭취한 열량과 소모한 열량의 불균형을 그 근본적 원인으로 판단할 수 있다. 비만은 또한 당뇨병의 44%, 심혈관 질환의 23%, 그리고 기타 비만관련 암질환의 7~40%의 발병원인으로 보고되고

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Evidence of Endoplasmic Reticulum Stress Mediating Cell Death in Transplanted Human Islets

Cell Transplantation, 2012
A key limitation to the success of islet transplantation is islet cell exhaustion and cell death during islet isolation and following transplantation. Endoplasmic reticulum (ER) stress has been identified as an important mechanism in the development of β-

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
