text: Cells migrate through crowded microenvironments within tissues during normal
development, immune response, and cancer metastasis. Although migration through
pores and tracks in the extracellular matrix (ECM) has been well studied, little
is known about cellular traversal into confining cell-dense tissues. We find that
embryonic tissue invasion by Drosophila macrophages requires division of an epithelial
ectodermal cell at the site of entry. Dividing ectodermal cells disassemble ECM
attachment formed by integrin-mediated focal adhesions next to mesodermal cells,
allowing macrophages to move their nuclei ahead and invade between two immediately
adjacent tissues. Invasion efficiency depends on division frequency, but reduction
of adhesion strength allows macrophage entry independently of division. This work
demonstrates that tissue dynamics can regulate cellular infiltration.

text: Cellular metabolism must adapt to changing demands to enable homeostasis.
During immune responses or cancer metastasis, cells leading migration into challenging
environments require an energy boost, but what controls this capacity is unclear.
Here, we study a previously uncharacterized nuclear protein, Atossa (encoded by
CG9005), which supports macrophage invasion into the germband of Drosophila by
controlling cellular metabolism. First, nuclear Atossa increases mRNA levels of
Porthos, a DEAD-box protein, and of two metabolic enzymes, lysine-α-ketoglutarate
reductase (LKR/SDH) and NADPH glyoxylate reductase (GR/HPR), thus enhancing mitochondrial
bioenergetics. Then Porthos supports ribosome assembly and thereby raises the
translational efficiency of a subset of mRNAs, including those affecting mitochondrial
functions, the electron transport chain, and metabolism. Mitochondrial respiration
measurements, metabolomics, and live imaging indicate that Atossa and Porthos
power up OxPhos and energy production to promote the forging of a path into tissues
by leading macrophages. Since many crucial physiological responses require increases
in mitochondrial energy output, this previously undescribed genetic program may
modulate a wide range of cellular behaviors.

text: Arabidopsis PIN2 protein directs transport of the phytohormone auxin from
the root tip into the root elongation zone. Variation in hormone transport, which
depends on a delicate interplay between PIN2 sorting to and from polar plasma
membrane domains, determines root growth. By employing a constitutively degraded
version of PIN2, we identify brassinolides as antagonists of PIN2 endocytosis.
This response does not require de novo protein synthesis, but involves early events
in canonical brassinolide signaling. Brassinolide-controlled adjustments in PIN2
sorting and intracellular distribution governs formation of a lateral PIN2 gradient
in gravistimulated roots, coinciding with adjustments in auxin signaling and directional
root growth. Strikingly, simulations indicate that PIN2 gradient formation is
no prerequisite for root bending but rather dampens asymmetric auxin flow and
signaling. Crosstalk between brassinolide signaling and endocytic PIN2 sorting,
thus, appears essential for determining the rate of gravity-induced root curvature
via attenuation of differential cell elongation.
