Wishing a prosperous new year, two horses, which carry a red and white twisted rope resembling F-actin, are galloping. This reminds us of pseudopodia that are strongly growing by the power generated from G-actin polymerization. Designed by TRAIS Co., Ltd. (Kobe, Japan)
Mt. Fuji glows with the red tint of the rising sun. A bank of clouds is lying behind the mountain and presenting its characteristic appearance. There are lying clouds in shapes like, from the bottom, rough endoplasmic reticulum, smooth endoplasmic reticulum, and transport vesicles. There is seen above it a bank of clouds well-formed like a Golgi apparatus, and further above it smaller clouds like secretory vesicles. There may also be seen clouds like mitochondria. Wonder if it's just an illusion. Designed by TRAIS Co., Ltd. (Kobe, Japan)
|FRET (Fluorescence Resonance Energy Transfer), which is a phenomenon of energy transfer between two adjacent fluorescent molecules, has been applied to visualization of interaction between proteins in living cells and so on. To carry out high-efficiency FRET, not only the distance between two molecules must be very close (less than about 10 nm) but the relative orientation of two chromophores must also be optimized. One of the women in this picture carries the other with attention paid on how they are oriented to each other, and successfully lightens the plum blossoms just like FRET. Designed by TRAIS Co., Ltd. (Kobe, Japan)|

“Yaedatami” or an eightfold straw mat is a tatami specially prepared for use in religious services. A craftsman folds “tatamiomote” or woven soft rush straws with edging of specially designed Nishijin brocade several times over so as to perfectly align patterns of creases of the folded edgings. We use the design to schematically illustrate the somitogenesis in vertebrates. As the U-shaped presomitic mesoderm moves tailward, periodic waves of gene expression form pairs of somites one after another from the anterior end. “Otoshine” or the top cushion has a mark of an embryo woven into it. If you carefully look at the edging of “otoshine”, you can find it bears the process of segmentation in Drosophila, a species which forms all of its segments simultaneously.

Phages have greatly contributed to flourishing of molecular biology, and even today, they remain useful tools for scientists. In this illustration, a “hikeshi” (a firefighter in Edo) is carrying a “matoi” (a standard of his firefighter team as its symbol), which is likened to a phage. Meanwhile lanterns held by firefighters in the back look like bacteria.
Kites are flying in the early spring in a town with the backdrop of Mt.Fuji. Being steered into the wind and skillfully manipulated via string, the kites look like metaphase chromosomes aligned on the equator of the cell.
A piece inspired by a fusion of traditional Japanese beauty and life sciences. There are a Japanese cosmetic brush and a hand mirror on a black board. An embryo fantastically reflected in the mirror suddenly reminds you of something: the brush is a very micropipette, and the embryo must be a subject of an experiment with it. How cleavage of a fertilized egg occurs is drawn like a family crest on a vanity bag, as if it indicates whom these cosmetic tools belong to. In the embryo, a lacZ marker transgene was driven by a connexin43 (Cx43) promoter in neural crest cells. Courtesy of Osamu Chisaka.

This month’s feature is molecular chaperones which support correct protein folding. A child represents a protein (or a polypeptide) trying to fold correctly, while a woman represents a chaperone teaching calligraphy. Pieces of paper scattered on the floor are misfolded polypeptides. In reality, accumulation of misfolded polypeptides will cause various kinds of diseases. Chaperones are essential to life.
Speaking of Japanese seasonal tradition in May, you may think of carp streamers flying high over roofs of houses. People fly the carps, wishing for healthy growth of their children. This month, we have painted each scale of a carp streamer, mimicking a mechanism known as lateral inhibition. So, how would you grade the work?
kaiA, kaiB and kaiC genes and their products constitute a core circadian oscillator in the cyanobacterium S. elongates (derived from a Japanese term “kai”, which means rotation or cycle number). KaiA stimulates autophosphorylation of KaiC, whereas KaiB promotes autodephosphorylation of KaiC. It is the particular characteristics of system of cyanobacteria that the three purified Kai proteins and ATP can reconstitute a circadian oscillation in a test tube. We overlay a diagram of this feedback loop on an armillary sphere in an Ukiyoe, which was installed at an astronomical observatory in Edo era. The pattern of roof tiles in the foreground depicts a circadian oscillation.

Soma Nomaoi, Soma horse chasing festival, which used to be a religious ceremony, is now an event held in Soso District (north-eastern part of Fukushima prefecture) every July. In ancient times, Samurais captured wild horses roaming around fields, and dedicated them to Kami. Although wild horses were extinct early in Meiji era, later, the ceremony has been revived as an event in which hundreds of horsemen scramble for holy flags. In this cover art, we let warriors on horsebacks carry flags with arms of model organisms, the strongest tools for our research, to join this event. It is Arabidopsis thaliana (right foreground) what colors the field, the stage for the festival, and streamers of double helix are fluttering in the far background.
All the traditional Japanese sweets replicate the development of an early embryo from the first cleavage. Each confectionery expresses, from the back, a fertilized egg undergoing the first cleavage (made from “konashi” or kneaded sweet bean paste, coated with “kudzu” starch), a 2-cell-stage embryo (“aoume” or a green plum), an 8-cell-stage embryo (modified from “kiku” or chrysanthemum), a morula (“domyoji” or a sweet pink mochi), and a tailbud (modified from “magatama” or a claw-shaped bead). So, which one would you like to start with?
| Tadataka Inou (1745-1818) was over 50 when he retired from the family business and started to learn Western astronomy. At the age of 55, he led a surveying team to travel throughout Japan islands (40,000 kilometers in total) spending 17 years, and accomplished the first Japanese actual measured map, Dai Nihon Enkai Yochi Zenzu, based on the data collected during the survey. The map created about 200 years ago was so accurate that it later amazed the western surveying teams visiting the country. This month’s cover art illustrates Tadataka Inou and his team working together to accomplish a metabolic map. Inspired by Figure 2-35 in The Molecular Biology of the Cell, 5th ed. (Alberts et al. 2008).|

Protruding from each side of the mountain (represented as cells) like classical cadherin cell adhesion molecules, bridge girders are mutually bound so as to link two summits (cells). This month’s cover art represents the mountain surfaces as plasma membranes, the bridge girders and trails as classical cadherins (where each of the bridge girders shows five extracellular cadherin (EC) domains and a transmembrane domain, while the trails show intracellular domains), huts along the trails as catenins, groves of trees as actin filaments, and cliffs as an intercellular space. Sealed with a word “adhesion” at lower right.
What if there had been an international academic meeting held in Edo era? It must be like this. This picture illustrates how successfully a poster session was being held. A student-like young man on the far left is performing a presentation on a poster titled “idenshi-kara-saibou-made” (in English, “from Genes to Cells”). Another poster on the right end is the one for the 36th Annual Meeting of the Molecular Biology Society of Japan (MBSJ) (3-6 December, 2013, Kobe). Inside the floor, in the back on the right of the picture, attendees from inside and outside the country are having a discussion over snacks.
|Following last month’s issue, let’s imagine what an international academic meeting was like in Edo era. No better place can be found than a Kabuki stage for the oral presentation! The presentation is full house. A presenter (probably the president of this meeting?) stands at the center of the stage, and on his left hand, the chairperson of this session is sitting on the stage. Each paper lantern hanging from the ceiling has a picture of crest imitating model organisms. There is a poster for the 36th Annual Meeting of the Molecular Biology Society of Japan (MBSJ) (3-6 December, 2013, Kobe) behind the presenter.|

Set against the backdrop of Mt. Fuji, a skilled craftsman is fixing a broken wooden barrel by excising damaged bases and then introducing new ones. We liken this to the process of DNA repair thereby recovering hydrogen bonds between each pair of bases.
A fisherman on a cliff is pulling nets as if synchronizing circadian rhythms with the help of light shining down from the sky.
|A woman with a hanagasa (a traditional hat decorated with ornamental flowers) is performing a Japanese classical dance.|
The ornaments on the hat actually are gap junctions, and some of them are opened and allowing small molecules to pass through.

Branched waterfalls are reminiscent of the cell lineage of the nematode Caenorhabditis elegans from a zygote to a newly hatched larva.
|Regulated cell adhesion and cellular motility underlies dynamic cell rearrangement, which is essential for morphogenesis of various organs. We expressed this process using a picture of a stone levee along a canal.|| |
The Epigenetic landscape, which was firstly depicted by C. H. Waddington in 1950's, has often been used to illustrate cellular differentiation in the process of biological development. Presented on our cover is a timeless representation of the landscape where we see worshippers of Mt. Fuji are being reprogrammed on the slope. Some are climbing high to acquire pluripotency, while others are traversing the foot, and being directly reprogrammed.
|This cover depicts The Bridge in the NGS Rain where people are being exposed to torrents of genomic information, that is, fruits of next generation sequencing. The man standing in the middle of the bridge is pictured deep in thought, considering how to utilize this sequence data set of the ALDH2 gene. Another man, shown to the right with a sake bottle, is eager to know whether he is genetically predisposed with a high tolerance for alcohol or not.|| |
Coloring the summer night sky of Japan, this firework has a theme of the half spindle of animal mitotic cells. A centrosome containing a pair of centrioles is located in the center, and astral microtubules extend to the up to the left, while polar microtubules extend to the opposite direction. Japanese technology currently produces cutting-edge fireworks, and it should not be difficult to produce such fireworks in reality.
The theme of this month is “translation”. The information in DNA is first transcribed into mRNA, which is further converted into a chain of amino acids. This conversion process is called translation and a stop codon marks the end of translation in each mRNA molecule. In the illustration, a fictitious translator on completion of his translation seals the letter with a Chinese character “stop” and amber (which is a nickname for UAG, one of the stop codons). The face of the seal depicts letters of “translation”.
|Cilia of eukaryotic cells undulate in a well-balanced motion and play a variety of roles essential to life. The cover art for this month’s issue presents movements of ciliated cells of respiratory epithelium in an analogy to Susuki glasses, a feature of autumn in Japan. The cilia beat in a given direction defined by the structure of roots. In the picture, waves to the right are generating a current. There is a goblet cell that secretes mucus being drawn at the slightly right of the center on the near side of the picture. The moon and geese are also arranged in the picture so as to evoke another feature of autumn in Japan.||The principle mechanism of skin pattern formation in vertebrates can be explained with a mathematical model proposed by Alan Turing (reaction-diffusion system, 1952). In this month's cover art, wild-type and mutant tigers are glaring to the right (at a dragon coming up in December issue). In the front of the wild-type tiger, a rock is illustrated with three peaks representing waves of activator and inhibitor that are observed in the reaction-diffusion system. Furthermore, two bamboos having four internodes represent transmembrane domains in a certain variant of connexin (a subunit of the gap junctions), which is a four-span transmembrande protein and one of the responsible genes for morphological mutation in a vertebrate.|| |
The cover art of this month is the second part of the series from the November issue. It describes how cellular slime molds assemble into a dragon. The cellular slime molds normally are individual of an amoeba-like unicellular organism. However, when they starve, tens of thousands of cells aggregate in one place to form a cluster. The cluster hugs the ground like a slug, searches for the right place for making spores, and forms a fluting body (lower part of the ground).

Grand Sumo showing a YOKOZUNA or grand champion and “hands” of supporters are pulling the horizontal rope of the kesho-mawashi. They want to tie the kesho-mawashi, but simultaneously, they are making a new horizontal rope from an older vertical rope, using Holliday junction-like structure.
A beautiful woman of the Heian period is pulled by a dog and peeks out from behind a bamboo blind, which is likened to experimental data of DNase I footprint. Data: Genes to Cells 15(5), pp537-552 (2010).
A scene from a Chinese-inspired vigorous dragon dance in a festival in Kyushu, Japan. The dragon is likened to a messenger RNA (mRNA), expressing transcription with DNA template.

Importance of bidirectional transportation between TOHOKU and surrounding districts. The “Kaido” expressed as a stone-pave street is designed to look like microtubules. Carts going left and pulled by bulls and messengers going right are expressions of motor proteins with cargos in eukaryote cells.
Being inspired by the similarity in the appearance, KOKESHIs are portrayed as metaphase chromosomes, which pair KOKESHIs. It deserves attention that each pair of KOKESHI is designed the same and tied with a thread at their necks (kinetochores) each other.
A huge and prestigious shrine that looks like Izumo-Taisha shrine at a glance. White zigzag paper streamers like a leucine zipper-type transcription factor are tucked in a giant sacred rope (dextrorotatory double-helix). The paper streamers probably bind to specific sequences of dsDNA expressed as a sacred rope.

Harvest time. Toreutics on a guard of a Japanese sword has a design of ears of rice and a butterfly landing on them. No, they actually are DNA winding around nucleosome.
The Thunder God is generating the action potential, which is not lightning, in a neural network. The illustration is paired with that of December Issue.
Since nerves of higher animals have myelin sheaths, an action potential is propagated rapidly (phenomenon called a saltatory conduction) like the swift wind. The wind god is likened to an action potential that conduct bounces to be propagated.
