The goals of this study were to identify differences in learners' and teachers' perspectives on EFL learners' language anxiety, to identify the differences among teachers coping with learners' language anxiety, and to find how learners cope with their language anxiety. The research was effectuated by means of a survey questionnaire and interviews. The data were collected from 92 teachers and 230 students in four different school settings. There were the $6^{th}$ grade 50 primary school learners, the $2^{nd}$ grade 60 middle school learners, the $11^{th}$ grade 60 high school learners of, and the $2^{nd}$ and $3^{rd}$ grade 60 university learners. There were also 26 primary school teachers, 22 middle school teachers, 21 high school teachers, and 23 university teachers. The findings reveal that there were differences in responses among the respondents. The findings suggest that teachers need to pay attention to their particular learners' anxiety sources: especially in the case of primary school setting, the activity of answering teachers' questions for teachers was the primary source of learner's anxiety, in the case of middle school settings, translating sentences in English into Korean, in the case of high school setting, checking unknown vocabulary, and in the case of university settings, university learners felt anxious when classmates spoke fluently. The implications of the study indicate that these aspects should be handled carefully to motivate certain group of learners.

개똥쑥 추출물(AAE)은 암에 효과적인 약초로 알려져 있다. Apoptosis는 프로그램화된 세포사멸로 미토콘드리아는 세포사멸 조절에 중요한 역할을 한다. 이 연구는 A549 폐암세포에서 Bcl-2 하위조절과 미토콘드리아 경로를 통한 AAE의 p53 비의존적인 세포사멸을 보여주고 있다. AAE는 p-Akt, cox-2, p53 그리고 미토콘드리아 조절 단백질을 통해 암세포의 사멸을 촉진한다. p-Akt/cox-2 단백질은 세포 증식과 생존에 중요한 역할을 한다고 알려져 있다. Bax, Bak, Bim과 같이 세포사멸을 촉진하는 Bcl-2 단백질은 미토콘드리아 외막의 투과성을 조절한다. AAE의 처리는 p-Akt, p-Mdm2, cox-2 그리고 anti-apoptotic 단백질과 같이 세포사멸을 억제하는 단백질들의 발현을 감소시키는 반면에 암 억제자인 p53과 pro-apoptotic 단백질들을 증가시킨다. Bax/Bak의 활성화는 caspase를 활성화시키기 위해 cytochrome c를 미토콘드리아에서 세포질로 방출하도록 한다. Caspase-3는 apoptosis 과정과 관련된 주요 effector caspase이다. Caspase-3는 일반적으로 pro-enzyme형태로 세포질에 존재한다. Apoptosis의 개시단계에서 caspase-3는 proteolytic cleavage에 의해 활성화되고 활성화된 caspase-3는 PARP를 분해한다. Apoptosis와 관련된 단백질들의 신호전달 사이의 상관관계를 알기 위해 Pifithrin-α (p53 inhibitor)와 Celecoxib(cox-2 inhibitor)을 처리했다. 이러한 결과를 통해 A549 폐암 세포에 AAE를 처리하였을 때 p53-independent 경로를 통해 apoptosis가 유도된다는 것을 확인하였다. The extract from Artemisia annuain L.(AAE) is known as a medicinal herb that is effective against cancer. Apoptosis is the process of programmed cell death, and mitochondria are known to play a central role in cell death control. In this study, we evaluated the p53-independent apoptosis of extract of AAE through downregulation of Bcl-2 and the mitochondrial pathway in A549 (lung cancer cells). AAE may exert cancer cell apoptosis through regulating p-Akt, Cox-2, p53 and mitochondria-mediated apoptotic proteins. p-Akt/cox-2 is known to play an important role in cell proliferation and cell survival. The Bcl-2 pro-apoptotic proteins (such as Bax, Bak and Bim) mediate the permeabilization of the mitochondrial outer membrane. Treatment of AAE reduces p-Akt, p-Mdm2, cox-2 and antiapoptotic proteins (such as Bcl-2), while tumor suppressor p53 and pro-apoptotic proteins. Activation of Bax/Bak releases cytochrome c from mitochondria to the cytosol to activate a caspase. Caspase-3 is the major effector caspase associated with apoptotic pathways. Caspase-3 generally exists in cytoplasm in the form of a pro-enzyme. In the initiation stage of apoptosis, caspase-3 is activated by proteolytic cleavage and activated caspase-3 cleaves poly (ADP-ribose) polymerase (PARP). We treated Pifithrin-α (p53 inhibitor) and Celecoxib (Cox-2 inhibitor) to learn the relationship between the signal transduction of proteins associated with apoptosis. These results suggest that AAE induces apoptosis through a p53-independent pathway in A549.

Akt 및 mTOR는 세포 생존에 필수적인 경로로 세포 성장과 증식 등에서 중요한 역할을 하는 것으로 알려져 있다. 본 연구에서는 항암 및 항균 효과가 있는 것으로 알려진 개똥쑥(Artemisia annua L.)에 의한 HepG2 간암세포의 apoptosis 유도 효과를 확인하였다. 본 연구 결과에 의하면 개똥쑥 추출물의 처리 농도가 증가함에 따라 HepG2 세포의 생존율은 억제되었으며, 이는 apoptosis 유도 효과에 의한 것임을 세포의 형태적 변화와 flow cytometry를 통해 확인하였다. 그리고 mitopotential assay와 caspase-3/7 activity assay, western blotting으로 Bcl-2 family 단백질을 확인함으로써 apoptosis 경로 중 내인성 경로(intrinsic pathway)에 의해 apoptosis가 일어남을 알 수 있었다. 이러한 효과는 Akt/mTOR의 활성 저해와 연관이 있었으며 Akt/mTOR의 저해제인 LY294002/rapamycin을 개똥쑥 추출물과 병행처리하였을 경우 개똥쑥 추출물에 의한 apoptosis 효과를 더욱 증대시켰다. 따라서 Akt/mTOR의 저해는 개똥쑥 추출물의 apoptosis 효과를 상승시켰으며 이에 따라 미토콘드리아의 기능 손상과 caspase 활성의 증가를 통해 이루어짐을 확인하였다. The Akt/mammalian target of the rapamycin (mTOR) pathway is activated in the majority of human cancers. Activation of the Akt/mTOR pathway confers resistance to many types of cancer therapy. In this study, we evaluated the apoptotic effect of ethanol extract of Artemisia annua L. through down-regulation of Akt signal pathways and the mitochondrial pathway in hepato-carcinoma cells (HepG2). A. annua extract is known as a medicinal herb that is effective against cancer. We evaluated anti-proliferative activity by MTT-based viability assay and apoptotic effect by Annexin-V/PI staining, mitochondrial membrane potential (MMP), and caspase-3/7 activity as determined by flow cytometry. A. annua treatment led to loss of MMP, resulting in cytochrome c-inducible activation of caspase-3/7. Treatment with A. annua extract reduced activities of Akt/mTOR/anti-apoptotic proteins (such as Bcl-2 and Bcl-XL), leading to increased activation of tumor suppressor p53 and pro-apoptotic proteins (such as Bax and Bak). We applied LY294002 (inhibitor of Akt) and rapamycin (inhibitor of mTOR) to determine the relationship between signal transduction of proteins associated with apoptosis. LY294002 and rapamycin significantly reduced cell viability and increased apoptosis. These results indicate that Bcl-2 and caspase-3 are key regulators in A. annua extract-induced apoptosis in HepG2 cells and are controlled through the Akt/mTOR signaling pathway.

김보민(Bo Min Kim),김근태(Guen Tae Kim),임은경(Eun Gyeong Lim),김은지(Eun Ji Kim),김상용(Sang Yong Kim),하성호(Sung Ho Ha),김영민(Young Min Kim) 한국생물공학회 2015 KSBB Journal Vol.30 No.5

In this study, extract from Artemisia annua in L.(AAE) is known as a medicinal herb that is effective against cancer. The cell cycle is regulated by the activation of cyclindependent kinase (CDK)/cyclin complex. We will focus on regulation of CDK2 by cyclin E. cyclin E is associated with CDK2 to regulate progression from G1 into S phase. Akt is known to play an important role in cell proliferation and cell survival. Activation of Akt increases mTOR activity that promotes cell proliferation and cancer growth. In this study, we investigated that AAE-induced cell cycle arrest at G1/S phase in HCT116 colon cancer. Treatment of AAE shows that reduced activation of Akt decreases mTOR/Mdm2 activity and then leads to increase the activation of p53. The active p53 promotes activation of p21. p21 induces inactivation of CDK2/ cyclin E complex and occurs cell cycle arrest at G1/S phase. We treated LY294002 (Akt inhibitor) and Rapamycin (mTOR inhibitor) to know the relationship between the signal transduction of proteins associated with cell cycle arrest. These results suggest that AAE induces cell cycle arrest at G1/S phase by Akt/mTOR pathway in HCT116 colon cancer cell.
