In this issue of Developmental Cell, Dickinson etal. (2017) and Rodriguez etal. (2017), along with Wang etal. (2017) in Nature Cell Biology, show how PAR protein oligomerization can dynamically couple protein diffusion and transport by cortical flow to control kinase activity gradients and polarity in the C.elegans zygote.

Reporting in Nature Cell Biology, Lin and Wang (2017) show that bacterial methyl metabolism impacts host mitochondrial dynamics and lipid storage in C.elegans. The authors propose a model whereby bacterial metabolic products regulate a nuclear hormone receptor that promotes lipid accumulation through expression of a secreted Hedgehog-like protein.

Prenatal exposure to environmental agents can influence the fitness of not only the fetus, but also subsequent generations. In a recent study, Wang et al. demonstrated that feeding ursolic acid (UA), a plant-derived compound, to Caenorhabditis elegans mothers during their reproductive period prevented neurodegeneration in not only their offspring, but also the F2 progeny.

Transmembrane channel-like (TMC) proteins have been implicated in hair cell mechanotransduction, Drosophila proprioception, and sodium sensing in the nematode C.elegans. In this issue of Neuron, Wang etal. (2016) report that C.elegans TMC-1 mediates nociceptor responses to high pH, not sodium, allowing the nematode to avoid strongly alkaline environments in which most animals cannot survive.

OBJECTIVES: Both cysteine proteinase inhibitors (CPIs) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) play important roles in the pathogenesis of parasites and their relationship with the hosts. We constructed a new eukaryotic recombinant expression plasmid pcDNA3.1(+)-BmCPI/BmGAPDH of periodic Brugia malayi for investigation of the DNA vaccine-elicited immune responses. MATERIALS AND METHODS: We cloned a gene encoding the CPIs and GAPDH from periodic B. malayi into vector pcDNA3.1. The composited plasmid or the control was injected into the tibialis anterior muscle of the hind leg in BALB/c mice, respectively. The target genes were detected by reverse transcription-polymerase chain reaction in muscle tissues. The stimulation index (SI) of T-lymphocyte proliferation and the levels of interferon-gamma (INF-g) and interleukin-4 ( IL-4) in serum were detected by thiazolyl blue tetrazolium blue and enzyme-linked immunosorbent assays. RESULTS: The pcDNA3.1(+)-BmCPI/BmGAPDH was amplified from muscle tissues of the mice after immunisation. The SI of the immunised group was significantly higher than that of the two control groups (P < 0.05). The levels of INF-g and IL-4 of pcDNA3.1(+)-BmCPI/BmGAPDH group were both higher than those of the two control groups (P < 0.05). The level of INF-g of pcDNA3.1(+)-BmCPI/BmGAPDH group was significantly higher than that of pcDNA3.1(+)-BmCPI/CpG group (P < 0.05). CONCLUSIONS: We conclude that the recombinant plasmid pcDNA3.1(+)-BmCPI/BmGAPDH could elicit specific humoural and cellular immune responses in mice.

Live imaging is an important tool to track dynamic processes such as neuronal patterning events. Here, we describe a protocol for time-lapse microscopy analysis using neuronal migration and dendritic growth as examples. This protocol can provide detailed information for understanding cellular dynamics during postembryonic development in Caenorhabditis elegans (C. elegans). For complete details on the use and execution of this protocol, please refer to Feng etal. (2020), Li etal. (2021), and Wang etal. (2021).

By measuring prevailing distances between YY, YR, RR, and RY dinucleotides in the large database of the nucleosome DNA fragments from C. elegans, the consensus sequence structure of the nucleosome DNA repeat of C. elegans was reconstructed: (YYYYYRRRRR)(n). An actual period was estimated to be 10.4 bases. The pattern is fully consistent with the nucleosome DNA patterns of other eukaryotes, as established earlier, and, thus, the YYYYYRRRRR repeat can be considered as consensus nucleosome DNA sequence repeat across eukaryotic species. Similar distance analysis for [A, T] dinucleotides suggested the related pattern (TTTYTARAAA)(n) where the TT and AA dinucleotides display rather out of phase behavior, contrary to the "AA or TT" in-phase periodicity, considered in some publications. A weak 5-base periodicity in the distribution of TA dinucleotides was detected.

Cell size is an important determinant of body size. While the genetic mechanisms of cell size regulation have been well studied in yeast, this process has only recently been addressed in multicellular organisms. One recent report by Wang et al. (2002) shows that in the nematode C. elegans, the TGFbeta-like pathway acts in the hypodermis to regulate cell size and consequently body size.((1)) This finding is an exciting step in discovering the molecular mechanisms that control cell and body size.
