Summary: Hypoxia is a common pathological condition induced by various events, with the body's adaptation to it being crucial for health and disease. HIFs, a family of transcription factors, play a key role in cellular responses to hypoxia and are increasingly viewed as potential targets for treating a range of hypoxia-associated diseases. The role of HIFs in adaptation to hypoxia is universal across tissue types, including the CNS, where they are involved in regulating neurogenesis, nerve cell differentiation, and neuronal apoptosis, potentially offering new therapeutic opportunities.

Summary: The study suggests that irradiated BDNF-eMSCs outperform naive MSCs in attenuating severe hypoxic ischemic brain injury, showing better paracrine potency and therapeutic efficacy by reducing cytotoxicity, oxidative stress, cell death, brain injury progression, apoptotic cell death, astrogliosis, inflammatory responses, and impaired motor function. The findings indicate that BDNF gene-transfected MSCs may offer a more effective therapeutic strategy against severe neonatal HI brain injury.

Summary: The study demonstrated the essential role of Nrf2 in optimal HIF1 alpha activation in hypoxia and the downregulation of Nrf2 in hypoxia through mitochondrial signaling, with restoration upon reoxygenation. Nrf2 and HIF1 alpha interact to provide optimal metabolic and cytoprotective responses in ischemic AKI.

Summary: Cardiovascular diseases are the leading cause of death worldwide, and hypoxia-inducible factors (HIFs) play an important role in their pathogenesis. Recent studies have revealed the role of cell-specific HIFs in various cardiovascular diseases, but the potential clinical application of HIF inhibitors in the treatment of cardiovascular diseases is not well understood.

Summary: A large number of neutrophils infiltrate tumors and contribute to the inflammatory tumor microenvironment. The metabolic status of these neutrophils and their role in tumor progression were investigated in a mouse model of pancreatic ductal adenocarcinoma (PDAC). Tumor-infiltrating neutrophils showed enhanced glycolytic activity compared to neutrophils from the bone marrow and blood of the same mouse. Deletion of hypoxia-inducible factor 1-alpha (HIF-1 alpha) in neutrophils reduced tumor burden and improved survival in the mouse model, indicating a potential target for metabolic modulation in cancer.

Summary: This study identified TRAA2A as an important hypoxia-associated gene in pancreatic cancer, which is associated with tumor progression and metastasis. TRAA2A is regulated by hypoxia-inducible factor HIF1 alpha and promotes the proliferation and motility of pancreatic cancer cells via activation of the AKT pathway. Therefore, TRAA2A may serve as a novel molecular target for investigating the hypoxic response of pancreatic cancer cells.

Summary: Research from Sweden and the United States has shown that the expression of ER beta in prostate cells is related to the nuclear translocation of EGFR, which may be associated with the development and progression of prostate cancer. The use of ER beta agonists and inhibitors may help maintain ER beta expression and offer some benefits to patients.

Summary: ER beta plays a unique role in estrogen signaling, acting not only as a precursor of androgens but also opposing androgen signaling and exerting independent effects in the CNS. While ER beta agonists show promising results in rodent models of neurodegenerative diseases, their efficacy in humans is yet to be confirmed. The differential expression of ER beta splice variants between humans and rodents highlights the need for further research.

Summary: Comparing gene expression profiles of malignant parts and normal adjacent parts of TNBC breasts revealed that CYP-mediated pathways may drive TNBC. However, despite being expressed in TNBC, ER13 is unlikely to be a tumor suppressor as its absence of main tethering partners renders it ineffective on genes related to proliferation and inflammation.

Summary: This review discusses the role of liver X receptors (LXRs) in glial cells in the central nervous system (CNS). LXRs regulate genes involved in cholesterol homeostasis, inflammatory responses, and glutamate homeostasis. Studies on LXR knockout mice have shown that LXR beta is crucial for the health of various types of neurons in both CNS and peripheral nervous system. LXRs are also important for cerebrospinal fluid homeostasis. Despite the neurological deficits observed in LXR-deficient rodents, defective LXR signaling has only been identified in multiple sclerosis among human neurodegenerative diseases. Targeting LXRs in glial cells may hold potential for treating neurodegenerative diseases and disorders caused by abnormal neuronal migration during development.

Summary: This study systematically reviews models that aim to provide patient-specific predictions of pre-treatment rebleeding risk in patients with aneurysmal subarachnoid hemorrhage. The reported discriminative performance of the models varied, and no model showed consistently low bias risk and clinical applicability in all domains. Only one model was formulated using a patient cohort that underwent contemporary, evidence-based aneurysm treatment practices, but this model lacked calibration or clinical utility.

Summary: This study retrospectively reviewed the clinical characteristics and outcomes after surgical revascularization for adult Moyamoya disease (MMD) in a Southeast Asian cohort. The incidence of postoperative transient ischemic attack (TIA)/stroke was 25.9%, with most cases occurring within 7 days postoperatively. Risk factors for 30-day postoperative TIA/stroke included a higher number of preoperative TIAs/strokes and indirect revascularization.

Summary: This study investigated the forward head posture (FHP), thoracic kyphosis, and their relationship in individuals with migraine compared to healthy controls. The results showed that patients with migraine had a greater FHP and thoracic kyphosis. This suggests that a 3-dimensional objective measurement could be a reliable tool for evaluating posture analysis in clinical practice.
