Development and functioning of the embryo sac in four triploid banana cultivars [PDF]
, 2023 The objective of this work was to investigate the causes of sterility in a new set of triploid banana (Musa spp.) cultivars and to assess the chances of obtaining some progenies by manual cross-pollination.

Schematic representation of the flower and the embryo sac of Arabidopsis thaliana.
, 2012 The flower of Arabidopsis thaliana consists of four whorls of organs: sepals, petals, anthers (male reproductive organs) and carpels (female reproductive organs). The carpels are fused and form the ovary, which harbors around fifty ovules.

Studying fibroblast growth factor (FGF) mediated cell migration in "Drosophila" larval air sacs [PDF]
, 2005 Invertebrates and vertebrates use FGF signaling in many developmental processes. Mesoderm formation, limb outgrowth but also the development of the vascular system and the lung rely on FGF ligands.

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer
Molecular Oncology, EarlyView.Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Enlarging cells initiating apomixis in Hieracium praealtum transition to an embryo sac program prior to entering mitosis [PDF]
, 2013 Hieracium praealtum forms seeds asexually by apomixis. During ovule development, sexual reproduction initiates with megaspore mother cell (MMC) entry into meiosis and formation of a tetrad of haploid megaspores.

Molecular Oncology, EarlyView.BCL9 and BCL9L drive bladder cancer progression by enhancing β‐catenin signaling, promoting proliferation, migration, invasion, and organoid growth. Genetic depletion of BCL9(L) suppresses malignant phenotypes, while pharmacological disruption of the β‐catenin/BCL9(L) complex with ZW4864 inhibits canonical Wnt signaling and tumor‐associated cellular ...
