  • Pituitary tumor transforming gene (PTTG1) is widely detected in many tumors. Increasing evidence reveals that PTTG1 is associated with cell proliferation, cellular transformation and apoptosis. However, the functions of PTTG1, especially its role in DNA damage-induced apoptosis, remain largely unclear. In this report, we used UV irradiation to induce apoptosis in HeLa cells to examine the role of PTTG1 in UV-induced apoptosis by RNAi-mediated knockdown and overexpression of PTTG1. RNAi-mediated knockdown of PTTG1 expression increased and overexpression of PTTG1 decreased the UV-induced apoptosis. Furthermore, UV irradiation decreased PTTG1 mRNA and protein expression. These effects were found to be mediated by JNK pathway. Therefore, PTTG1 had an important anti-apoptotic role in UV-induced apoptosis and this role was mediated by JNK pathway. These results may provide important information for understanding the exact role and the regulation mechanism of PTTG1 in UV-induced apoptosis.

  • Human papillomavirus (HPV) is the major cause of cervical cancer, a deadly threat to millions of females. The early oncogene product (E7) of the high-risk HPV16 is the primary agent associated with HPV-related cervical cancers. In order to understand how E7 contributes to the transforming activity, we investigated the structural features of the flexible N-terminal region (46 residues) of E7 by carrying out N-15 heteronuclear NMR experiments and replica exchange molecular dynamics simulations. Several NMR parameters as well as simulation ensemble structures indicate that this intrinsically disordered region of E7 contains two transient (10-20% populated) helical pre-structured motifs that overlap with important target binding moieties such as an E2F-mimic motif and a pRb-binding LXCXE segment. Presence of such target-binding motifs in HPV16 E7 provides a reasonable explanation for its promiscuous target-binding behavior associated with its transforming activity.

  • Loeys-Dietz syndrome (LDS) is an autosomal dominant disorder caused by heterozygous mutations in the genes encoding transforming growth factor-${\beta}$ receptor type 1 or 2. It is typically characterized by a triad of hypertelorism, cleft palate or bifid uvula, and arterial tortuosity with aneurysm or dissection. Characteristic vascular abnormalities such as tortuosity, aneurysms, dissections, and stenosis are the most severe complications of LDS and can occur in the neurovascular system. We report a 5-year-old boy who presented with headaches and neurovascular abnormalities and was diagnosed with LDS with a novel mutation of the TGFBR1 gene. It is the first Korean report of neurovascular abnormalities in LDS.

  • Human papillomavirus (HPV), especially type 16 and 18, has been closely associated with carcinomas and uterine cevical cancer, recently. From in vitro assays, E6 and E7 genes of HPV16 are closely linked with transformation of cell lines of rodent fibroplasts. However, the transforming activity of E6 and E7 genes of HPV type 16 in vivo has not been fully elucidated. For explaining this mechanism, we prepared a expression system with the promoter of mouse mammary tumorvirus long terminal repeat and E6E7's open reading frames. This expression system was introduced in rodent cell lines, No. 7, 3Y1 and shown normal transforming abilities. And, we produced transgenic mice with E6, E7 expression system. These transgenic mice were confirmed from Southern blot analysis. One male of them was observed enlargement of the testis after 5 months postdelivery.

  • Fibroblast is constantly subjected to mechanical loads in connective tissues where mechanical signals are converted to intercellular biochemical events. The aim of this study is to understand the effects of tensile stress on the neurotrophin (NT) and transforming growth factor (TGF) expression of fibroblast in vitro. Nerve growth factor (NGF) stimulates fibroblast migration, and TGF is related to tissue repair. In this study, at the uniaxial stretch of 10% strain and frequency of 0.5 Hz, different resting times of 0, 20, and 60 min are placed in between 10 min stimulations periods. Results show increase in NGF mRNA levels and a substantial decrease in NT3 mRNA after 1 hr of stimulation, indicating that the tensile stress may regulate NGF and NT3, key factors for the neurocosmetic applications. The mRNA level for TGF-${\alpha}$ and TGF-${\beta}2$ had increased up to two-folds after 1 hr of stimulation, showing that the tensile stress may control TGF, an important part of wound healing.

  • Streptococcus pneumoniae, pneumococcus, is the most common cause of community-acquired pneumonia (CAP). CAP is an important infectious disease with high morbidity and mortality, and it is still one of the leading causes of death worldwide. Many genetic factors of the host and various environmental factors surrounding it have been studied as important determinants of the pathophysiology and outcomes of pneumococcal infections. Various cytokines, including transforming growth factor $(TGF)-{\beta}1$, are involved in different stages of the progression of pneumococcal infection. $TGF-{\beta}1$ is a cytokine that regulates a wide range of cellular and physiological functions, including immune and inflammatory responses. This cytokine has long been known as an anti-inflammatory cytokine that is critical to preventing the progression of an acute infection to a chronic condition. On the other hand, recent studies have unveiled the diverse roles of $TGF-{\beta}1$ on different stages of pneumococcal infections other than mitigating inflammation. This review summarizes the recent findings of the role of $TGF-{\beta}1$ on the pathophysiology of pneumococcal infections, which is fundamental to developing novel therapeutic strategies for such infections in immune-compromised patients.

  • FoxO3a is a member of the forkhead box class O (FoxO) transcription factor family and an important regulator of apoptosis. This work aimed to elucidate the involvement of FoxO3a in transforming growth factor-${\beta}1$(TGF-${\beta}1$)-induced apoptosis in FaO rat hepatoma cells. TGF-${\beta}1$ caused a time-dependent activation of FoxO3a and a subsequent increase in FoxO response-element-containing luciferase reporter activity, which was Akt-sensitive. The FaO cells stably transfected with a wild type FoxO3a were more susceptible to the formation of apoptotic bodies, populations of sub-G1 apoptotic cells, and collapse of the mitochondrial-membrane potential triggered by TGF-${\beta}1$. In contrast, transfection with small-interfering RNA (siRNA) oligonucleotide specific for FoxO3a significantly inhibited caspase activation in FaO cells treated with TGF-${\beta}1$. It thus appears that FoxO3a plays a crucial mediatory role in the TGF-${\beta}1$ signaling pathway leading to apoptosis.

  • This study researches the application methods of Wearable Technology (WT) realizing the convergence of Design and Electronics that could broaden the fashion expression boundaries to correspond to current convergence trends. For this, students in the Department of Fashion design and the Department of Electronics conducted an oriented convergence-design-workshop. The initial step of the workshop, included a lecture on WT including existing cases and brainstorming. As a result, two types of concepts; 'Light' using the lighting technology and 'Complex' using transforming and lighting technologies together were generated. Designers created garments that did not externally expose digital devices and engineers then configured basic systems with the minimum size of the devices applying. At the development stage, designers constructed internal structures of garments which do not influence the comfort situation and activities of those wearing the garments. Engineers then adjusted and finished the fashion prototypes' whole WT systems drawing on designers' guidelines. As the result of this study's workshop, the fashion prototypes were extracted by collaboration according to WT concepts; therefore, there could be the promising potential to broaden fashion expression boundaries through the application of WT.
