About the Lab
Professor Sang-Min Jeon's research lab focuses on cellular signaling pathways and metabolic regulation in cancer and neurological disorders. The lab investigates key regulators such as AMP-activated protein kinase (AMPK), hexokinase 2 (HK2), and lipocalin 2 (LCN2), exploring their roles in tumor metabolism, metastasis, and neuropathic pain. By integrating molecular and cellular biology with in vivo disease models, the lab uncovers novel mechanisms linking metabolism, inflammation, and disease progression. Current research emphasizes the dual roles of metabolic kinases and signaling molecules in both tumor survival and neuroinflammatory conditions.

155'-adenosine monophosphate (AMP)-activated protein kinase (AMPK) is an evolutionarily conserved serine/threonine kinase that was originally identified as the key player in maintaining cellular energy homeostasis. Intensive research over the last decade has identified diverse molecular mechanisms and physiological conditions that regulate the AMPK activity. AMPK regulates diverse metabolic and physiological processes and is dysregulated in major chronic diseases, such as obesity, inflammation, di
Vitamin D, traditionally known as an essential nutrient, is a precursor of a potent steroid hormone that regulates a broad spectrum of physiological processes. In addition to its classical roles in bone metabolism, epidemiological, preclinical, and cellular research during the last decades, it revealed that vitamin D may play a key role in the prevention and treatment of many extra-skeletal diseases such as cancer. Vitamin D, as a prohormone, undergoes two-step metabolism in liver and kidney to
Numerous studies have shown that supraphysiological activation of AMPK could inhibit tumor growth. On the other hand, accumulating data also suggest that AMPK activity is required for tumor growth and migration. These findings suggest that physiological activation of AMPK is critical for tumor growth/migration, possibly through maintenance of ATP levels. Our recent study provides the first evidence that the maintenance of cellular NADPH homeostasis is the predominant mechanism by which AMPK prom
Hexokinase 2 (HK2), which catalyzes the first committed step in glucose metabolism, is induced in cancer cells. HK2's role in tumorigenesis has been attributed to its glucose kinase activity. Here, we describe a kinase independent HK2 activity, which contributes to metastasis. HK2 binds and sequesters glycogen synthase kinase 3 (GSK3) and acts as a scaffold forming a ternary complex with the regulatory subunit of protein kinase A (PRKAR1a) and GSK3β to facilitate GSK3β phosphorylation and inhibi
Lipocalin 2 (LCN2), which is also known as 24p3 and neutrophil gelatinase-associated lipocalin (NGAL), binds small, hydrophobic ligands and interacts with cell surface receptor 24p3R to regulate diverse cellular processes. In the present study, we examined the role of LCN2 in the pathogenesis of neuropathic pain using a mouse model of spared nerve injury (SNI). Lcn2 mRNA levels were significantly increased in the dorsal horn of the spinal cord after SNI, and LCN2 protein was mainly localized in
Monocyte chemoattractant protein-1 (MCP-1)/CCL2 is a member of the CC chemokine family that exhibits potent chemotactic activity for monocytes/macrophages. In the current study, the proportion of monocyte chemoattractant protein-1-immunoreactive (IR) neurons in the dorsal root ganglion (DRG) of rats was shown to increase markedly following adjuvant injection into the hindpaw. MCP-1-IR axon terminals were not found in the spinal cord or hindpaw of control or adjuvant-treated rats. Instead, the in
Co-occurring mutations in KEAP1 in STK11/LKB1-mutant NSCLC activate NFE2L2/NRF2 to compensate for the loss of STK11-AMPK activity during metabolic adaptation. Characterizing the regulatory crosstalk between the STK11-AMPK and KEAP1-NFE2L2 pathways during metabolic stress is crucial for understanding the implications of co-occurring mutations. Here, we found that metabolic stress increased the expression and phosphorylation of SQSTM1/p62, which is essential for the activation of NFE2L2 and AMPK,
건강을 중시하면서도 외식업체 영양표시에 대한 실질적인 관심과 활용이 부족한 소비자에게 도움이 되는 외식업 체 영양표시방안이 필요하다. 본 연구는 2010년부터 표시 의무화가 되는 외식업체 영양표시방안 수립에 소비자지 향적인 시사점을 제공하기 위하여 포커스그룹인터뷰와 소비자설문조사를 통해 외식업체 영양표시에 대한 소비자의 이용 현황과 욕구를 분석하여 외식업체 영양표시의 제공 방향을 도출하였다. 본 연구의 조사 결과, 현재 외식 소비자는 월 평균 7.63회 외식을 하고, 18.59만원을 지출하며, 분식, 한식, 고 기집 등 우리나라 전통식 메뉴를 자주 이용하고 있다. 외식 동기와 메뉴의 결정 요인은 가족과 친구의 의견과 맛으 로, 영양표시의 중요도는 낮았다. 영양표시는 주로 패스트푸드, 피자, 패밀리레스토랑에서 인식하고 있고, 그 외의 외식 유형에서는 거의 본 경험이 없었다. 외식 소비자는 메뉴를 결정하는 시점에 매장 내에서 영양표시를 주로 인 식하고 있었다. 외식업체 영양표시에 대한
Innocuous touch sensation is mediated by cutaneous low-threshold mechanoreceptors (LTMRs). Aβ slowly adapting type I (SAI) neurons constitute one LTMR subtype that forms synapse-like complexes with associated Merkel cells in the basal skin epidermis. Under healthy conditions, these complexes transduce indentation and pressure stimuli into Aβ SAI LTMR action potentials that are transmitted to the CNS, thereby contributing to tactile sensation. However, it remains unknown whether this complex play
맞벌이 가구의 증가로 영유아 보육서비스에 대해 사회 전반적으로 수요가 높은 상황에서 영유아 부모의 욕구를 반영한 보육서비스의 제공은 영유아 부모의 만족도를 높이고 심각한 사회 문제인 저출산 문제까지 해결할 수 있는 매우 중요한 사안이다. 본 연구는 영유아 보육서비스에 대한 부모의 욕구를 충족시킬 수 있는 방안 도출을 위하여 『한국아동패널 2008』 조사 결과를 바탕으로 만 2세 미만 아동의 보육서비스에 대한 부모의 소비실태와 만족도를 분석하였고, 다음의 결론을 도출하였다. 첫째, 만 2세 미만 아동 보육서비스의 주된 이용 동기는 어머니의 취업인 것으로 나타나 맞벌이 가구의 특성과 욕구가 반영된 영유아 보육서비스가 필요하다. 취업모의 출산 후의 원활한 직장 복귀를 돕고, 만 2세 미만 아동의 개인대리양육서비스에 대한 높은 수요를 충족시키기 위하여 아이돌보미 영아종일제 서비스의 대상 월령을 현재의 출산 후 3-12개월에서 2-24개월로 확대해야 한다. 또한, 맞벌이 가구의 총소득이 외벌
