miRNAs targeted transcription factors HaGATAa/b to mediate the post-mating switch in Helicoverpa armigera female reproductive behavior.

Background: The process of mating induces significant shifts in female reproductive behavior across various species, with the postmating behavioral switch playing a crucial role in insect reproduction. Previous studies have demonstrated the regulatory role of GATA transcription factors in vitellogenin transcription and egg formation in insects, while miRNAs have been implicated in modulating GATA expression and insect reproductive processes. Nevertheless, the precise regulatory mechanism underlying the interaction between miRNAs and GATA transcription factors in the postmating behavioral switch remains largely unexplored.

A novel 4-aminoquinoline chemotype with multistage antimalarial activity and lack of cross-resistance with PfCRT and PfMDR1 mutants.

Artemisinin-based combination therapy (ACT) is the mainstay of effective treatment of Plasmodium falciparum malaria. However, the long-term utility of ACTs is imperiled by widespread partial artemisinin resistance in Southeast Asia and its recent emergence in parts of East Africa. This underscores the need to identify chemotypes with new modes of action (MoAs) to circumvent resistance to ACTs.

"It Is What It Is" - The Lived Experience of Women With Breast Cancer Undergoing Axillary Lymph Node Dissection.

Purpose: The lived experience of women undergoing axillary procedures as part of their breast cancer (BC) treatment remains unexplored. This lack of in-depth understanding could hamper implementation of person-centred care, which is concerning because BC is the most common form of cancer in women. The aim of this study was therefore to explore the lived experiences of women undergoing axillary lymph node dissection (ALND) due to BC.

Coronavirus M protein promotes mitophagy over virophagy by recruiting PDPK1 to phosphorylate SQSTM1 at T138.

Autophagy plays a dual role in coronavirus infection, facilitating the elimination of either proviral components (virophagy) or antiviral factors such as mitochondria (mitophagy), leading to complex mechanisms of immune evasion. Understanding the mechanisms that govern the switch between the autophagic degradation of deleterious or beneficial substrates in coronavirus infection is crucial for developing precise drug targets to treat virus-induced diseases. However, this switch remains largely unknown.
