Identification and evaluation of suitable reference genes for gene expression studies in the whitefly Bemisia tabaci (Asia I) by reverse transcription quantitative realtime PCR [PDF]

open access: yes, 2014
This study presents a reliable method for performing reverse transcription quantitative realtime PCR (RT-qPCR) to measure gene expression in the whitefly Bemisia tabaci (Asia I) (Gennadius) (Hemiptera: Aleyrodidae), utilising suitable reference genes for

Effects of 17α‐Ethinylestradiol on Development and Gonadal Differentiation in the Estuarine Mummichog, Fundulus heteroclitus

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 2, Page 148-161, March 2026.
ABSTRACT In fish, sex determination and gonadal development are controlled by various genetic and environmental factors. In this study, experiments were conducted on the estuarine mummichog (Fundulus heteroclitus) to investigate gonadal differentiation following exposure to the synthetic estrogen, 17α‐ethinylestradiol (EE2).

Introns as Protective Buffers Against Transposable Elements Invasion During Genome Gigantism in a Newt

open access: yesGenes to Cells, Volume 31, Issue 2, March 2026.
In the giant Pleurodeles waltl genome, introns serve as “structural buffers,” absorbing transposable elements (TEs) to protect coding exons. While this enables “gene body inflation,” persistent TE accumulation eventually leads to transcriptional silencing and functional collapse, or “burst,” of the gene architecture.

Lipid profiling of the filarial nematodes Onchocerca volvulus, Onchocerca ochengi and Litomosoides sigmodontis reveals the accumulation of nematode-specific ether phospholipids in the host [PDF]

open access: yes, 2017
Onchocerciasis, a neglected tropical disease prevalent in western and central Africa, is a major health problem and has been targeted for elimination. The causative agent for this disease is the human parasite Onchocerca volvulus.

Vitellogenin synthesis in the avian liver. Vitellogenin is the precursor of the egg yolk phosphoproteins

open access: yesJournal of Biological Chemistry, 1975
Administration of estrogen to roosters induces the synthesis of egg yolk phosphoproteins in the liver. We have demonstrated that these proteins are synthesized in the form of a large precursor, vitellogenin, and that vitellogenin is the only phosphoprotein found in the plasma of the estrogen-treated rooster. Vitellogenin is cleaved to form the egg yolk

Susceptibility to the Neonicotinoid Pesticide Imidacloprid Is Linked to Life History Regulation in Honey Bees (Apis mellifera L.)

open access: yesMolecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT The Western honey bee (Apis mellifera) is a globally important pollinator. Its health in natural and managed populations is compromised by numerous factors, including pesticides. Neonicotinoid pesticides are widely used even though they can cause a variety of detrimental effects.

Endoplasmic Reticulum Stress Caused by Lipoprotein Accumulation Suppresses Immunity against Bacterial Pathogens and Contributes to Immunosenescence

open access: yesmBio, 2017
The unfolded protein response (UPR) is a stress response pathway that is activated upon increased unfolded and/or misfolded proteins in the endoplasmic reticulum (ER), and enhanced ER stress response prolongs life span and improves immunity. However, the

Culex quinquefasciatus vitellogenesis: morphological and biochemical aspects [PDF]

open access: yes, 2010
The vitellogenic process in Culex quinquefasciatus, which is triggered by a blood meal, involves the synthesis, distribution and storage of the nutrients necessary for embryo development. The fat body of an adult female Cx.

Recent advances in breeding and seed production of marine finfish [PDF]

open access: yes, 2015
Cage culture has made possible the large-scale production of commercial finfish in many parts of the world and can be considered as the most efficient and economical way of rising fish.
