Preparation of Parasite Protein Extracts and Western Blot Analysis

Bio-Protocol, 2014
In order to prepare protein extracts of Plasmodium falciparum blood stages for western blot analysis, infected red blood cells (iRBC) need to be separated from uninfected red blood cells (uRBC) which make up the bulk of the parasite culture. Depending on

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.

Western Blot Analysis of Chloroplast HSP70B in Chlorella Species

Bio-Protocol, 2013
Western blotting allows for the specific detection of proteins by an antibody of interest. This protocol utilizes isolation of total proteins protocol for Chlorella vulgaris prior to gel electrophoresis. After electrophoresis, the selected antibodies are

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

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

Molecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

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

Identificación de antígenos de quistes y trofozoítos de aislamientos colombianos de Giardia duodenalis reconocidos por IgA.

Biomédica: revista del Instituto Nacional de Salud, 2003
Se conoce poco acerca del papel de la IgA en la respuesta inmune de la giardiosis. El propósito de este trabajo fue identificar los antígenos estimuladores de la producción de IgA anti-Giardia duodenalis de aislamientos colombianos del parásito.

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
