The influence of hormones on negative action of light by tomatoes

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 1973
It is known that tomatoes require daily at least 4 hours darkness for a normal growth and reproduction. In continuous light they become chlorotic and do not bear fruits (1, 2, 3, 4). It was tempted to find possibilities to avoid this reaction.

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

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

Do You See What I See? Aspects of Color Choice and Perception in Ancient Egyptian Painting

Open Archaeology, 2018
Color in ancient Egypt has been examined through linguistics, anthropological theory and archaeological science. In recent years, attention has focused on the application of art historical theories of reception and perception to ancient Egyptian art, but

Theory of Dark Energy and Dark Matter

Journal of Mathematical Study, 2015
Summary: In a previous paper, a new set of gravitational field equations were derived based only on 1) the Einstein principle of general relativity, and 2) the principle of interaction dynamics, due to the the presence of dark energy and dark matter. With the field equations, we show that gravity can display both attractive and repulsive behavior, and ...

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.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Chorals of Light and Darkness: Multiple Identities in the World of Contemporary Lithuanian Music

Pitannâ Lìteraturoznavstva
Lithuanian composers in their own way fulfil M. K. Čiurlionis’s (1875–1911) visionary oath: the creation of the world through the synthesis of arts initiated by waves of imagination, i.e., their works show a tendency to create an organic whole or ...
