Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Acid and Alkaline Phosphatase Activity in the Indian Apple Snail Pila globosa (Swainson) During Aestivation [PDF]
Journal of Stress Physiology & Biochemistry, 2023 The Indian apple snail Pila globosa (Swainson) experiences an annual cycle of aestivation (summer sleep) as a survival strategy during a hot and dry period to avoid damage from high temperatures and the risk of desiccation.

, 2009 *Background* Our bones are remodelled repeatedly during life. A new and “healthy” bone tissue replaces the old one. Accordingly, the bone degrading cells, the osteoclasts, prefer old and fatigued bone.

Functional characterisation of a predicted chloroplastic plant protein phosphatase [PDF]
, 2009 The phosphatase AtPTPKISI is involved in the control of starch metabolism in Arabidopsis thaliana leaves at night. The SEX4 (Starch Excess 4) mutants, lacking this predicted phosphatase, have strongly reduced rates of starch metabolism.

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.

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

, 2013 Acid phosphatase activity was determined from whole cell lysates of F. tularensis acid phosphatase mutants by a fluorometric method using DiF-MUP as the substrate. The data are presented as percent of wild type phosphatase activity.

Molecular Oncology, EarlyView.Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Modifications induced by ascorbic acid on alkaline phosphatase fluorescence
, 1984 Ascorbic acid, isoascorbic acid and dehydroascorbic acid quench the tryptophyl fluorescence of alkaline phosphatase. The quenching is protein aspecific, although its extent reflects the different inhibitory efficiency of the compounds.

Molecular Oncology, EarlyView.The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and
