The commonly used eye-specific sev-GAL4 and GMR-GAL4 drivers in Drosophila melanogaster are expressed in tissues other than eyes also

M Ray, SC Lakhotia - Journal of genetics, 2015 - Springer
The binary GAL4-UAS system of conditional gene expression is widely used by Drosophila
geneticists to target expression of the desired transgene in tissue of interest. In many studies, …

Sex-specific splicing occurs genome-wide during early Drosophila embryogenesis

M Ray, AM Conard, J Urban, P Mahableshwarkar… - Elife, 2023 - elifesciences.org
Sex-specific splicing is an essential process that regulates sex determination and drives
sexual dimorphism. Yet, how early in development widespread sex-specific transcript diversity …

The large noncoding hsrω-n transcripts are essential for thermotolerance and remobilization of hnRNPs, HP1 and RNA polymerase II during recovery from heat shock …

SC Lakhotia, M Mallik, AK Singh, M Ray - Chromosoma, 2012 - Springer
The hs-GAL4 t -driven expression of the hsrω-RNAi transgene or EP93D allele of the
noncoding hsrω resulted in global down- or upregulation, respectively, of the large hsrω-n …

Over-expression of Hsp83 in grossly depleted hsrω lncRNA background causes synthetic lethality and l(2)gl phenocopy in Drosophila

M Ray, S Acharya, S Shambhavi, SC Lakhotia - Journal of biosciences, 2019 - Springer
We examined interactions between the 83 kDa heat-shock protein (Hsp83) and hsrω long
noncoding RNAs (lncRNAs) in hsrω 66 Hsp90GFP homozygotes, which almost completely …

Activated Ras/JNK driven Dilp8 in imaginal discs adversely affects organismal homeostasis during early pupal stage in Drosophila, a new checkpoint for …

Altered levels of hsromega lncRNAs further enhance Ras signaling during ectopically activated Ras induced R7 differentiation in Drosophila

M Ray, G Singh, SC Lakhotia - Gene expression patterns, 2019 - Elsevier
We exploited the high Ras activity induced differentiation of supernumerary R7 cells in
Drosophila eyes to examine if hsrω lncRNAs influence active Ras signaling. Surprisingly, either …

Dual DNA/RNA-binding factor regulates dynamics of hnRNP splicing condensates

M Ray, J Zaborowsky, P Mahableshwarkar… - bioRxiv, 2024 - biorxiv.org
Despite decades of research, mechanisms by which co-transcriptional alternative splicing
events are targeted to the correct genomic locations to drive cell fate decisions remain …

Getting started: altering promoter choice as a mechanism for cell type differentiation

M Ray, E Larschan - Genes & Development, 2020 - genesdev.cshlp.org
In this issue of Genes & Development, Lu and colleagues (pp. 663–677) have discovered a
key new mechanism of alternative promoter choice that is involved in differentiation of …

Altered hsrω lncRNA levels in activated Ras background further enhance Ras activity in Drosophila eye and induces more R7 photoreceptors

M Ray, SC Lakhotia - bioRxiv, 2017 - biorxiv.org
To examine role of hsrω nuclear lncRNAs in Ras signaling cascade, we down- or up-regulated
these transcripts in eye discs of Drosophila expressing sev-GAL4 driven activated ras …

The CLAMP GA-binding transcription factor regulates heat stress-induced transcriptional repression by associating with 3D loop anchors.

J Aguilera, J Duan, R Lee, M Ray, E Larschan - bioRxiv, 2023 - biorxiv.org
In order to survive when exposed to heat stress (HS), organisms activate stress response
genes and repress constitutive gene expression to prevent the accumulation of potentially toxic …
