The dpp gene originated from the silkworms is an important gene that is well conserved in the genome of humans, cattle, rodents, poultry and Drosophila. The dpp gene belonging to the TGF-beta (Transforming Growth Factor-beta) superfamily is known to play an important role in several developmental stages. The $TGF-{\beta}$ gene family is a genetically well-conserved and playing an important role gene family in various species such as determining cell proliferation and differentiation, apoptosis and cell fate. In this review, we have confirmed the following studies data. The recent studies on the silkworm dpp gene have confirmed for the first time the biological functions such as promoting osteogenesis activity. In addition, previous data shows that dpp have developmental functions such as morphogenetic materials at the blastophyllum stage, induction of the mesoblast at the late embryonic stage and involved in the proliferation and morphogenesis of imaginal disc in adult development. We found the splice variant of the dpp gene originated from the wildtype silkworm by using comparative genomics. It has provided important data for basic research based on genetics studies of these processes may promote a better understanding of evolution. Silkworm is a medicinal insect and is approved for its safety. It is used as a natural antibiotic for promoting growth as a medical material, a health functional food, and a feed additive. Therefore, it is necessary to present various data to obtain more value of functional insect.

코드분할 다중접속(CDMA) 시스템에서 대역확산 기법으로 사용되는 확산수열은 다중접속 간섭을 줄이고 높은 보안성을 위하여 상호상관관계가 낮고 선형복잡도가 큰 것으로 채택하는 것이 바람직하다. 그러나 수열군의 개수를 늘리고 선형복잡도를 높이기 위해서는 상호상관관계를 어느 정도 높이는 것은 불가피하다. 본 논문에서는 수열군의 개수가 크고 선형복잡도가 높은 확장 Zeng 수열을 제안하고 그 상호상관관계를 분석한다.

The SNF2/SW ATPase/helicase family comprises proteins form a variety of species with in vivo functions, such as transcriptional regulation, maintenance of chromosome stability during mitosis, and various types of DNA repair. Here, we reported the characterization of h게2+gene which was iolated by PCR amplification using the conserved domain of SNF2 motifs. Sequence analysis of PCR product showed striking evolutionary conservation among the SNF2 family of proteins. Two transcripts of 6.7 and 3.4 Lb were detected by Northern blot analysis. furthermore, the intensities of these two bands were increased by ultraviolet(UV) irradiation. These results indicate that the hrp2+ is a novel member of the SNF2 family of proteins and is one of the UV-inducible genes in S. pombe. To determine the level of transcripts of hrp2+ gene during cellular growth, Northern blot analysis were performed. This result indicates that the level of hrp2+transcript reached its maximum before cells entered the exponential growth phase. This suggests that hrp2+ gene is experssed mainly at the early stage of cell growth.

The purpose of this study was to identify general characteristics of social lifespaces in Korean family houses and to investigate the changes in the physical aspects and room functions of social lifespaces from Yi-dynasty to the present. The documentary research method was used for this study. Total of 972 out of 1,109 floor plans were analyzed for this study. The major findings were that changes of social lifespaces from Yi-dynasty to the present have been affected by natural and socio-cultural environments. The changes in the physical aspects of social lifespaces have shown from one or two social lifespaces to various single-purpose social lifespaces such as living room, family room, drawing room, and study room. In the past, the cnetral social lifespaces, Anbang(women's quarter) was larger than the living room/Daechung(wooden floor) but the living room in the present has become a central social lifespaces and larger. The room function of Anbang has changed from multi-purpose space to private space. Living room/Daechung had used as a pathway rather than a social lifespaces in the past but the living room has played many fuctional roles of family social activities in the present. The kitchen has also begun to use as a social lifespace. This is a new symptom that kitchen and dining spaces will be included as a new social lifespaces.

Metallothioneins are a group of low molecular mass and cysteine-rich metal-binding proteins, ubiquitously found in most living organisms. They play an important role in maintaining intracellular metal homeostasis, eliminating metal toxification and protecting against intracellular oxidative damages. Analysis of complete rice genome sequences revealed eleven genes encoding putative metallothionein (OsMT), indicating that OsMTs constitute a small gene family in rice. Expression profiling revealed that each member of the OsMT gene family differs not only in sequence but also in their tissue expression patterns, suggesting that these isoforms may have different functions they perform in specific tissues. On the basis of OsMT structural and phylogenetic analysis, the OsMT family was classified as two classes and class I was subdivided into four types. Additionally, in this paper we also present a complete overview of this family, describing the gene structure, genome localization, upstream regulatory element, and exon/intron organization of each member in order to provide valuable insight into this OsMT gene family.

Spectraplakins are crucially important communicators, linking cytoskeletal components to each other and cellular junctions. Microtubule actin crosslinking factor 1 (MACF1), also known as actin crosslinking family 7 (ACF7), is a member of the spectraplakin family. It is expressed in numerous tissues and cells as one extensively studied spectraplakin. MACF1 has several isoforms with unique structures and well-known function to be able to crosslink F-actin and microtubules. MACF1 is one versatile spectraplakin with various functions in cell processes, embryo development, tissue-specific functions, and human diseases. The importance of MACF1 has become more apparent in recent years. Here, we summarize the current knowledge on the presence and function of MACF1 and provide perspectives on future research of MACF1 based on our studies and others. [BMB Reports 2016; 49(1): 37-44]

Among the effector molecules connected with the group of cell surface receptors, Ras proteins have essential roles in transducing extracellular signals to diverse intracellular events, by controlling the activities of multiple signaling pathways. For over 20 years since the discovery of Ras proteins, an enormous amount of knowledge has been accumulated as to how the proteins function in overlapping or distinct fashions. The signaling networks they regulate are very complex due to their multiple functions and cross-talks. Much attention has been paid to the pathological role of Ras in tumorigenesis. In particular, human tumors very frequently express Ras proteins constitutively activated by point mutations. Up to date, three members of the Ras family have been identified, namely H-Ras, K-Ras (A and B), and N-Ras. Although these Ras isoforms function in similar ways, many evidences also support the distinct molecular function of each Ras protein. This review summarizes differential functions of Ras and highlights the current view of the distinct signaling network regulated by each Ras for its contribution to the malignant phenotypic conversion of breast epithelial cells. Four issues are addressed in this review: (1) Ras proteins, (2) membrane localization of Ras, (3) effector molecules downstream of Ras, (4) Ras signaling in invasion. In spite of the accumulation of information on the differential functions of Ras, much more remains to be elucidated to understand the Ras-mediated molecular events of malignant phenotypic conversion of cells in a greater detail.
