Necrosis is a major driver of thermal stress-induced mortality in Drosophila melanogaster larvae: cellular and molecular insights across acclimation phenotypes

Title: Necrosis is a major driver of thermal stress-induced mortality in

Drosophila melanogaster larvae: cellular and molecular insights across

acclimation phenotypes


Authors: Fatemeh Saeidi & Hervé Colinet


Affiliation: Université de Rennes, CNRS, ECOBIO (Ecosystèmes, biodiversité,

évolution) – UMR 6553, 35000 Rennes, France


This repository contains raw data files (in .txt format) associated with the study investigating

cell death dynamics induced by cold (-3°C) and heat (38°C) stress in third-instar

Drosophila melanogaster larvae. The study compared three acclimation phenotypes:

- LNA: Non-acclimated larvae (reared at 25°C for 4 days)

- LCA: Cold-acclimated larvae (reared at 15°C for 10 days)

- LHA: Heat-acclimated larvae (reared at 30°C for 3 days)


All data files are in tab-delimited text format (.txt).


For detailed statistical methods, please refer to the Materials & Methods

section of the associated manuscript.


LNA : Non-acclimated larvae (reared at 25°C for 4 days)

LCA : Cold-acclimated larvae (reared at 15°C for 10 days)

LHA : Heat-acclimated larvae (reared at 30°C for 3 days)

BS : Black spots (melanized lesions)

NBS : No black spots

Co : Unstressed control

CTCF : Corrected total cell fluorescence

ROS : Reactive oxygen species

GLM : Generalized linear model

GLMM : Generalized linear mixed model

PCA : Principal component analysis

RpL32 : Reference gene used for normalization

Informations supplémentaires

You can customize the template to suit your needs.

You can add

and remove fields and fill out default information (e.g. contact

details).

Fields you can not change in the default view may be accessible in the

more

comprehensive (and more complex) advanced view. You can even use the

XML editor

to create custom structures, but they have to be validated by the

system, so

know what you do :-)
