Translationally controlled tumor protein (TCTP) is a regulatory protein that plays pivotal roles in cellular processes including the cell cycle, apoptosis, microtubule stabilization, embryo development, stress responses, and cancer. However, the molecular mechanism by which it promotes tumor angiogenesis is still unclear. In this study, we explored the mechanisms underlying stimulation of angiogenesis by a novel TCTP.

Division of Developmental Biology and Physiology, Department of Biotechnology, Institute for Basic Sciences, Sungshin University, Seoul 02844, Korea.

Cellular prion protein (PrP) encoded at gene is well-known to form a misfolded isoform, termed scrapie PrP (PrP) that cause transmissible degenerative diseases in central nervous system. The physiological role of PrP has been proposed by many studies, showing that PrP interacts with various intracellular, membrane, and extracellular molecules including mitochondrial inner membrane as a scaffold. PrP is expressed in most cell types including reproductive organs.

In this study we investigated the effects of an 8-week table tennis exercise program with a task-oriented approach on visual perception and motor performance of 31 adolescents with developmental coordination disorder (DCD). The participants were identified by their teachers as having greater difficulty than their peers (450 students from three Korean middle schools) in physical education (PE) classes. On the Bruininks-Oseretsky Test of Motor Proficiency-2, these adolescents scored below the 15th percentile and showed difficulties in performing daily life activities due to motor performance problems; they did not have physical defects, intellectual or neurological impairments, or Attention Deficit Hyperactivity Disorder.

Previously, we reported that epidermal growth factor-like module-containing mucin-like hormone receptor-like 1 (EMR1/ADGRE1) is abnormally expressed in colon cancer (CC) and is a risk factor for lymph node metastasis (LNM) and poor recurrence-free survival in patients with abundant tumor-associated macrophages (TAMs). However, the signaling pathways associated with EMR1 expression in CC progression remain unclear. In this study, we aimed to explore the role of EMR1 and its signaling interactions with macrophages in CC progression.

Effects of Acetaminophen on Reproductive Activities in Male Golden Hamsters.

Dev Reprod

April 2023

Department of Life Science, College of Health Science and Welfare, Yong-In University, Yongin 17092, Korea.

Article Synopsis
  • Acetaminophen, a common pain reliever, can cause testicular damage and impair liver and kidney functions with high doses or long-term use.
  • A study on male golden hamsters divided them into groups receiving different acetaminophen doses and control conditions over 4 weeks, revealing that high doses led to small testicles without sperm.
  • The findings suggest that acetaminophen negatively impacts testicular health, causing regression in sperm production, especially when comparing treated animals to those in short photoperiod conditions.

AMPK inhibitor, compound C, inhibits coronavirus replication in vitro.

PLoS One

October 2023

Division of Biological Science and Technology, Yonsei University, Wonju, Republic of Korea.

The coronavirus disease (COVID-19) pandemic has resulted in more than six million deaths by October 2022. Vaccines and antivirals for severe acute respiratory syndrome coronavirus 2 are now available; however, more effective antiviral drugs are required for effective treatment. Here, we report that a potent AMP-activated protein kinase (AMPK) inhibitor, compound C/dorsomorphin, inhibits the replication of the human coronavirus OC43 strain (HCoV-OC43).

The purpose of this study was to examine the immediate and post effects of a parent-mediated physical activity intervention on the fundamental motor skills of autistic children. We randomly assigned parent-child dyads (n = 31) of autistic children aged 4-11 years into three groups (workshop, an online, or control group). Each dyad participated in a 12-week intervention and was given adapted physical activity equipment and over 200 activities via a mobile application.

February 2023

Physical Education Unit, School of Humanities and Social Science, The Chinese University of Hong Kong-Shenzhen, Shenzhen, China. Electronic address:

Objective: Falls are an important public health issue that poses a threat to the health of senior people and reduces their ability to maintain independence, which in turn reduces poor quality of life. Several studies have demonstrated a positive relationship between physical function and fall, it remains unclear whether there is an association between gait speed and fall-related injuries among the aging population, which represent the largest proportion of older adults in China. Therefore, the aim of this study was to examine the association between gait speed and fall-related injuries among older Chinese adults.

The human papillomavirus (HPV)-18 E7 (E7) oncoprotein is a major transforming protein that is thought to be involved in the development of cervical cancer. It is well-known that E7 stimulates tumour development by inactivating pRb. However, this alone cannot explain the various characteristics acquired by HPV infection.

CTRP1 Knockout Attenuates Tumor Progression in A549 and HCT116 Cancer Cells.

Cancers (Basel)

September 2022

Division of Biological Science and Technology, Yonsei University, Wonju 29493, Korea.

C1q and TNF-related 1 (C1QTNF1/CTRP1) is an adiponectin-associated protein belonging to the C1q/TNF-related protein family. Recent studies have shown that the C1q and TNF-related protein (CTRP) family is involved in cancer progression; however, the specific role of CTRP1 in tumor progression has not yet been elucidated. To examine the role of CTRP1 in tumor progression, we generated CTRP1 knockout A549 and HCT116 cell lines, which reduced the expression levels of nuclear factor (NF)-κB-dependent and metastasis-promoting transcripts.

We investigated the influence of the menstrual cycle (MC) on leukocyte response after exercise-induced muscle damage (EIMD). During the early follicular (E-FP, = 12) or mid-luteal phase (M-LP, = 12), 24 untrained females with eumenorrhea performed 60 eccentric exercises using nondominant arms. Blood samples were collected at pre- and 4, 48, and 96 h postexercise to analyze estradiol and progesterone concentrations, leukocyte count and fractionation, and creatine kinase (CK) activity.
