TLDR
A bacterial CRISPR RNA/Cas9 system is adapted to precisely engineer the Drosophila genome and it is reported that Cas9-mediated genomic modifications are efficiently transmitted through the germline.Abstract:
We have adapted a bacterial CRISPR RNA/Cas9 system to precisely engineer the Drosophila genome and report that Cas9-mediated genomic modifications are efficiently transmitted through the germline. This RNA-guided Cas9 system can be rapidly programmed to generate targeted alleles for probing gene function in Drosophila.read more

Coordinating transcription and replication to mitigate their conflicts in early Drosophila embryos
TL;DR: In this paper , a collision avoidance mechanism was proposed to prevent early transcription in Drosophila embryos during the early stages of the cell cycle by blocking DNA replication in nuclear cycles.

CRISPR/Cas9-mediated Tryptophan Hydroxylase 1 Knockout Decreases Calcium Transportation in Goat Mammary Epithelial Cells
TL;DR: It is suggested that TPH1 knockout decreased calcium transportation via PTHrP and calcium transportation-related factors in GMEC.

An RNA-based feed-forward mechanism ensures motor switching in oskar mRNA transport
TL;DR: A feed-forward mechanism, whereby dynein-dependent accumulation of staufen mRNA and protein in the oocyte enables motor switching during oskar mRNA transport by downregulating dyneIn activity, is identified.
Dissertation
Disclosing the zinc acquisition and homeostatic machinery of Leishmania parasites
TL;DR: The results gathered in this project suggest that alternative zinc uptake mechanisms might sustain parasite growth at initial phases of murine infection but, as disease progresses, LiZIP3 expression becomes essential for parasite survival in the spleen, implying that zinc withholding mechanisms are employed by the host to control infection.

Inhibition of serotonin expression in gut enteroendocrine cells results in conversion to insulin-positive cells
Domenico Accili,Ryotaro Bouchi +1 more
TL;DR: In this paper, the authors present methods for treating a disease or disorder in a mammal, preferably a human, associated with impaired pancreatic endocrine function, by administering a therapeutically effective amount of an enumerated active agent that reduces the expression, biosynthesis, signaling or biological activity of serotonin or increases its degradation, wherein administering comprises delivering the agent to Gut Ins- cells in the mammal.

TL;DR: It is found that, after viral challenge, bacteria integrated new spacers derived from phage genomic sequences, and CRISPR provided resistance against phages, and resistance specificity is determined by spacer-phage sequence similarity.
