Hedgehog (Hh) signaling plays pivotal roles in embryonic development and adult tissue homeostasis in species ranging from Drosophila to mammals. Malfunction of this pathway has been implicated in numerous human disorders including congenital anomalies and cancers, such as basal cell carcinoma, Medulloblastoma, lung cancer, liver cancer, etc. The Hh signaling is transduced by Smoothened (Sm... more |

| DNA methylation plays important biological roles in plants and animals. To examine the rice genomic methylation landscape and assess its functional significance, recently scientists from Kunming Institute of Zoology and their colleagues from Yunnan Academy of Agricultural Sciences, BGI-Shenzhen, Institute of Botany and Shanghai Cancer Institute generated single-base resolution DNA methylome map... more |

Human immunodeficiency virus infection / Acquired immunodeficiency syndrome (HIV/AIDS) is a disease of the human immune system caused by the human immunodeficiency virus. HIV has its high genetic variability and can be divided into two major types, HIV-1 and HIV-2. HIV-1 is the most common and pathogenetic strain of the virus.
For the pathology of HIV-1, dentritic cells (DCs), which were fi... more |

The rapidity, repeatability, cost-effectiveness, and comprehensiveness of metabarcoding will transform the environmental sciences and make it possible to use measures of biodiversity to address many of China’s needs.
Managing the forces that affect both the levels and distribution of biodiversity requires the ability to measure biodiversity comprehensively, reliably, repeatedly, and over l... more |

| Convergent evolution describes the acquisition of the same biological trait in unrelated lineages, whereas, parallel evolution is the development of a similar trait in related, but distinct, species descending from the same ancestor, but different clades. An iconic example of either of them via natural selection is echolocation by bats, toothed whales and dolphins. Echolocation, also called bio... more |
