Patients with acute myeloid leukemia (AML) who are ineligible for intensive chemotherapy have limited therapeutic options. Previous research suggests hypomethylating agents combined with venetoclax are effective for this group, but the hypomethylating agent must be given via parenteral administration or intravenous injection outside of the digestive tract. In a Phase II study, researchers led by Farhad Ravandi, M.D., and Alexandre Bazinet, M.D., evaluated an oral combination of decitabine and cedazuridine (ASTX727) plus venetoclax in 62...

Osteoclast cells are responsible for the resorption of bone structure and minerals, and their dysregulation is associated with osteoporosis, or decreased bone mineral density. Building upon previous work showing that MALAT1, a long noncoding RNA (lncRNA), suppresses breast cancer metastasis, Li Ma, Ph.D., and colleagues noted that a specific mutation in MALAT1 was associated with low bone mineral density and sought to determine the role of MALAT1 alternations in bone diseases. MALAT1 deficiency led to osteoporosis and more severe bone metastases of...

While positron emission tomography (PET) scans are highly effective in detecting lung cancer, their accessibility is limited, especially in low-income regions. To address this issue, researchers led by Jia Wu, Ph.D., Jianjun Zhang, M.D., Ph.D., and Carol Wu, M.D., leveraged deep learning techniques to generate synthetic PET scans from more widely available computed tomography (CT) scans. Radiologists validated the imaging quality and tumor contrast between the synthetic and actual PET images, and the researchers demonstrated the superior diagnostic...

Cancers progress and continuously adapt, making them challenging to treat. As cancer cells replicate and evolve, distinct cellular lineages, or subclones, compete to dominate and drive tumor progression. Researchers led by I-Lin Ho, Ph.D., and Andrea Viale, M.D., developed a new model for pancreatic cancer to study subclone evolution within tumors and metastases. They found that subclones undergo continuous fluctuations in representation during tumor growth, even without any external treatment, with dominant subclones suddenly collapsing...

Hematopoietic stem cells (HSCs) typically differentiate to replenish peripheral immune cells and undergo self-renewal to retain an adequate supply of parent cells, but the mechanisms regulating HSCs and preventing uncontrolled dysfunction are poorly understood. The STAT3 protein facilitates the maturation of immune system cells, but its role in HSCs is difficult to study because STAT3 deficiency or deletion in hematopoietic cells can induce systemic inflammation, impacting HSC activity. To address this, researchers led by Stephanie Watowich, Ph.D.,...
