Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Targeting transcription factors associated with hemoglobinopathies: Lessons from successful interventions and implications for cancer

Molecular Oncology, EarlyView.
This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...

Spatial biology in cancer epigenetics

Molecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

The Spare Embryo: A Red Herring in the Embryo Experimentation Debate

, 1993
Whenever embryo experimentation is discussed the question of whether it is preferable to use spare or specifically produced ('research') embryos for destructive embryo experimentation always enters the debate at some stage.

Characterization of the RhoGAP proteins RGA-3 and RGA-4 and the centrosomal protein SAS-5 in the early "Caenorhabditis elegans" embryo [PDF]

, 2007
The Caenorhabditis elegans embryo serves as a great tool to study cell biological processes like polarization and cell divison. The first cell division is unequal and cell polarization is dependant on the Rho GTPase regulated rearrangement of the cell ...

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Embryo Research: The Ethical Geography of the Debate

, 1997
Three basic political positions on embryo research will be identified as libertarian, conservative, and social-democratic. The Human Embryo Research Panel will be regarded as an expression of the social-democratic position.

Transplantation of a polyembryonic wasp embryo: A technique for transferring endoparasitic embryo into the host egg [PDF]

, 2005
Concealed development of many animal embryos prevents examination of development and limits the application of embryo manipulation techniques aimed at understanding developmental processes.

APOBEC3 activity and DNA polymerase‐ε deficiency are associated with distinct IDH1 R132 hotspot mutations

Molecular Oncology, EarlyView.
Isocitrate dehydrogenase 1 (IDH1) mutations are highly recurrent in multiple human cancer types, including cholangiocarcinoma and glioma. IDH1 R132C is the most common IDH1 mutation in cholangiocarcinoma and likely arises from APOBEC3A‐ or APOBEC3B‐mediated deamination.

Generation of Functional GnRH-Responsive Pituitary-like Organoids from Ovine Embryonic Stem Cells

Cells
The pituitary gland is a master regulator of endocrine and reproductive physiology; however, the lack of physiologically relevant in vitro models in livestock species has limited studies of pituitary development and endocrine function. Although pituitary
