Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Enhancing GNSS RTK Solutions with Random Sample Consensus

, 2023
Precise positioning with Global Navigation Satellite Systems (GNSS) can be achieved by using the real-time kinematic (RTK) solution. A GNSS RTK solution was improved using an innovative approach based on Random Sample Consensus (RANSAC).

Current Situation of GNSS Networks in Romania

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture, 2019
Nowadays, the need for a more precise positioning is a very high, therefore very demanding one, and this is one of the reasons why very large research funding is allocated in satellite technology, the second reason being global geopolitics situation. New

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

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

Comparison of classical-RTK and network-RTK surveying methods in coastal regions

Turkish Journal of Geosciences, 2023
Since the beginning of human life, human beings have wanted to know their location, and have therefore tried to find out where they are and where they are going throughout their lives. Researches and inventions that have shaped this situation have followed one another.
