Metástases medulares e encefálicas de ependimomas mixopapilares.

Acta Médica Portuguesa, 2001
After a brief introduction about the clinical, histological and therapeutic characteristics of myxopapillar spinal ependymoma of cone medullar and filum terminale, three cases with medullar and intracranial seeding of myxopapillar spinal ependymoma are ...

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Metástases cerebrais. Revisão de uma populuao hospitalar.

Acta Médica Portuguesa, 1996
Cerebral Metastases are diagnosed in approximately 20-30% of patients with primary tumours. Because of the improvement of central nervous system imagining technology and of the newly effective therapeutic schemes, the incidence of this particular type of

Flow Enabled Target Capture Halbach‐based magnetic enrichment increases circulating tumor cell capture from blood in metastatic cancer patients

Molecular Oncology, EarlyView.
Pair‐wise comparison of the CellSearch and FETCH enrichment technologies for circulating tumor cells (CTCs) from metastatic breast, prostate, and small cell lung cancer patients shows an increased capture of CTCs using FETCH enrichment. The clinical implementation of circulating tumor cells (CTCs) as a predictive tool for therapy efficacy in the ...

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

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

Intraoperative ultrasonography for presumed brain metastases: a case series study

Arquivos de Neuro-Psiquiatria, 2012
Brain metastases (BM) are one of the most common intracranial tumors and surgical treatment can improve both the functional outcomes and patient survival, particularly when systemic disease is controlled.

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

Efeito Anti-Tumoral dos Bisfosfonatos: uma Nova Perspectiva Terapêutica

Revista Brasileira de Cancerologia, 2004
Os bisfosfonatos (BFs) são potentes inibidores da reabsorção óssea mediada por osteoclastos. Essas drogas são efetivas na redução do cálcio sérico em pacientes com hipercalcemia maligna, assim como também no tratamento da dor óssea, osteoporose e ...
