The impact of stress on mental and digestive health has been extensively studied, with chronic stress being associated with various disorders. However, age-related differences in the response to acute stress, both behaviorally and physiologically, remain poorly understood. Therefore, this study aimed to develop a model to detect transient stress in mice of different ages.

Article Synopsis
  • - The study investigates Semaphorin 5A (SEMA5A), which was found to act as a tumor suppressor in lung cancer, specifically in nonsmoking women, by inhibiting cell proliferation and migration.
  • - Researchers focused on evaluating different domains of SEMA5A to understand their roles in lung adenocarcinoma cell lines, observing that overexpression of the full-length protein and its extracellular domain effectively reduced growth and movement of lung cancer cells.
  • - Microarray analysis revealed that SEMA5A influences the expression of genes related to the 'Interferon Signaling' pathway, which was confirmed through various validation methods, highlighting its importance in SEMA5A's tumor-suppressive effects. *

Cardiovascular disease (CVD) is the leading cause of mortality in diabetes mellitus (DM). Immunomodulatory dysfunction is a primary feature of DM, and the emergence of chronic kidney disease (CKD) in DM abruptly increases CVD mortality compared with DM alone. Endothelial injury and the accumulation of uremic toxins in the blood of DM/CKD patients are known mechanisms for the pathogenesis of CVD.

Semaphorin 5A (SEMA5A), a member of the semaphorin family, plays an important role in axonal guidance. Previously, the authors identified another possible role of SEMA5A as a prognostic biomarker for non‑smoking women with lung adenocarcinoma in Taiwan, and this phenomenon has been validated in other ethnic groups. However, the functional significance of SEMA5A in lung adenocarcinoma remains unclear.

Background: Homeostasis is a crucial concept used to describe the condition of patients and the roles of herbs in traditional Chinese medicine. Qi-deficiency pattern is one of the conditions when loss of homeostasis and is usually characterized by symptoms including lassitude, spontaneous sweating, and a weak pulse, which are not easy to quantitate. and were usually prescribed for carriers with hepatitis and patients with metastatic colon cancer, because these patients tended to experience fatigue.

For a newly synthesized compound, identifying its target protein is a slow but pivotal step toward understand its pharmacologic mechanism. In this study, we systemically synthesized novel manzamine derivatives and chose 1-(9'-methyl-3'-carbazole)-3, 4-dihydro-β-carboline (MCDC) as an example to identify its target protein and function. MCDC had potent toxicity against several cancer cells.

Background & Aims: This study examined the effects of a traditional Chinese medicine decoction, Kuan-Sin-Yin (KSY), on patients with chronic hepatitis C (CHC) in a randomised and placebo-controlled clinical trial.

Methods: This trial enrolled 70 subjects with CHC who were randomised into 2 groups each with 35 participants. In total, 29 participants in the therapeutic group took 100mL of the herbal decoction daily, whereas 28 in the control group took an herbal placebo with the same dose and frequency for the 6-week study.

Background: Kuan-Sin-Yin (KSY) is a traditional Chinese medicine (TCM) decoction, which has been shown to have cytostatic effects on cancer cells and involved in the TCM theory of promoting yin-yang balance.Sonce many cancer patients suffer from autonomic dysfunction (AD), which correspond to yin-yang imbalance in TCM. The aim of this study is to evaluate the possible effect of KSY in metastatic colon cancer (mCRC) patients with AD.

Hepatocellular carcinoma is one of the most common cancers in the world. Previously, we found that the level of glucocorticoid receptor was significantly higher in hepatocellular carcinoma than in adjacent liver tissues. Moreover, in vitro and in vivo studies showed that glucocorticoid stimulated the growth of hepatoma cells.

Synopsis of recent research by authors named "Pin-Hao Ko"

  • - Pin-Hao Ko's recent research focuses on the interactions between stress, immune response, and cancer biology, highlighting age-dependent stress effects in mice, the tumor-suppressing role of semaphorin 5A, and the mechanisms linking diabetes and cardiovascular disease.
  • - The study on acute stress in mice aimed to uncover how different ages respond behaviorally and physiologically to stress, while investigations into semaphorin 5A reveal its potential as both a prognostic biomarker and tumor suppressor in lung adenocarcinoma.
  • - Additional work includes exploring traditional Chinese medicine's efficacy, particularly the Kuan-Sin-Yin decoction, in enhancing liver function and ameliorating symptoms in chronic hepatitis C and metastatic colon cancer patients.
