“It has been postulated that the clinical benefit of adding POM results from enhanced immunocompetency.”
BUFFALO, NY - January 23, 2025 – A new editorial was published in Oncoscience’s Volume 12 on January 14, 2025, titled “Pomalidomide improved immune profiles in myeloma."
The editorial by researchers Hannah Seah, Vaishnavi Reddy Bade, Lakshmi Bhavani Potluri, Srikanth Talluri, and Rao H. Prabhala from Dana-Farber Cancer Institute, VA Boston Healthcare System, and Harvard Medical School, discuss how the drug pomalidomide (POM) can help improve the immune system in patients with hard-to-treat multiple myeloma, a type of blood cancer. The authors explain that adding pomalidomide to standard treatments may help strengthen the immune system and improve patient outcomes.
Multiple myeloma affects plasma cells in the bone marrow. It weakens the immune system, making patients more vulnerable to infections and other complications. While treatments have improved in recent years, the disease often returns, creating an urgent need for new strategies.
The editorial reviews different studies, including some conducted by the authors, showing that patients who received pomalidomide along with standard drugs like velcade, dexamethasone, or lenalidomide had stronger immune responses compared to those who did not receive the drug.
Clinical trials have shown that patients treated with pomalidomide experienced a longer period without disease progression—20.7 months compared to 11.6 months in patients who did not receive it. The editorial explains that pomalidomide works by enhancing key immune cells, such as T cells and natural killer (NK) cells, which helps the body recognize and destroy cancer cells.
At a molecular level, the drug helps break down proteins that suppress immune function, allowing the body to trigger a stronger response against cancer cells. The authors suggest that these effects could explain the clinical benefits seen in patients treated with pomalidomide-based regimens.
“POM targets Cereblon, which is part of the CRL4 E3 ubiquitin ligase, leading to the degradation of Ikaros and Aiolos, which are T cell repressors.”
The authors emphasize that these immune-boosting effects could make pomalidomide a valuable option for patients whose myeloma has returned after previous treatments. By restoring immune cell function, pomalidomide may help slow disease progression and improve survival rates.
In conclusion, the editorial underscores the potential of pomalidomide as a key player in the treatment of multiple myeloma. By enhancing the immune function and improving progression-free survival, the drug offers a new strategy for patients facing limited treatment options.

The PREPSOIL project, a pivotal initiative within the EU's Mission Soil framework, will host an engaging webinar on February 13, 2025, focusing on the importance of soil literacy among young people. The event highlights the vital connection between young citizens and soil health, offering educators innovative ways to integrate soil-related topics into their curriculum.
As part of the Mission Soil's eight goals, increasing soil literacy across Member States aims to foster greater awareness, involvement, and proactive behavior toward soil health. By embedding soil health education in school curriculums, the initiative seeks to empower the next generation to take informed ...

WASHINGTON, Jan. 23, 2025 – Many science fiction authors try to incorporate scientific principles into their work, but Ian Tregillis, who is a contributing author of the Wild Cards book series when he’s not working as a physicist at Los Alamos National Laboratory, took it one step further: He derived a formula to describe the dynamics of the fictional universe’s viral system.
In independent research published in the American Journal of Physics, from AIP Publishing, Tregillis and George R.R. Martin derive a formula for viral behavior in the Wild Cards universe.
Wild Cards is a science fiction series written by a collection of authors and ...

The remains of the earliest dinosaurs may lie undiscovered in the Amazon and other equatorial regions of South America and Africa, suggests a new study led by UCL (University College London) researchers.
Currently, the oldest known dinosaur fossils date back about 230 million years and were unearthed further south in places including Brazil, Argentina and Zimbabwe. But the differences between these fossils suggest dinosaurs had already been evolving for some time, pointing to an origin millions of years earlier.
The new study, published in the journal Current Biology, accounted for gaps in ...

About The Study: The results of this retrospective cohort study of 44,000 individuals suggest that fasting plasma glucose level, age, body mass index (BMI), and male sex were all associated with development of diabetes, with significant interaction between these variables. These data contribute to understanding the clinical course of diabetes and highlight the substantial individual variation in diabetes risk according to commonly measured clinical variables. The findings facilitate lifestyle and pharmacologic interventions to treat those at highest risk of diabetes to reduce future morbidity and mortality. Further work is needed to validate this risk ...

About The Study: In this cohort study, food insecurity in pregnancy was associated with a higher risk of perinatal complications, and these associations were overall attenuated to the null among individuals who received food assistance in pregnancy. These findings support clinical guidelines of screening for food insecurity in pregnancy and provide evidence to expand food assistance programs that may help improve maternal and neonatal outcomes.

About The Study: In this cross-sectional study, in-home cannabis smoking was associated with significantly increased odds of child exposure to cannabis smoke, as assessed by urinary cannabinoid biomarkers. As young children spend most of their time at home, reducing in-home cannabis smoking could substantially reduce their exposure to the toxic and carcinogenic chemicals found in cannabis smoke.

Researchers have found that a newly developed diet inspired by the eating habits of non-industrialised societies can significantly reduce the risk of a number of chronic diseases – and are to share recipes with the public.
Industrialised diets—high in processed foods and low in fiber— have contributed to a substantial rise in chronic diseases like obesity, diabetes, and heart disease, in affluent countries such as Ireland.
A paper published today in the prestigious scientific journal Cell shows that a newly developed diet that mimics eating habits in non-industrialissed ...

130 years after a fungus-eating plant received its name, a Kobe University researcher has uncovered the purpose of the structure that inspired its name — revealing a novel mechanism by which plants ensure reproduction.
MAKINO Tomitaro, a towering figure in Japanese botany, named around 1,000 species and discovered about 600 new plants between 1887 and 1957. Among his notable discoveries was the diminutive orchid Stigmatodactylus sikokianus, first identified in 1889. After Makino’s discovery, the plant was named for the unique, tiny finger-like appendage (the “dactylus” part) on its stigma, the flower’s ...

Genetically tailored treatment plans for children with a type of kidney cancer could help provide the most effective care while minimising side effects as much as possible.
Researchers at the Wellcome Sanger Institute, Cambridge University Hospitals NHS Foundation Trust, Great Ormond Street Hospital, the University of Würzburg, and their collaborators, have mapped the genetic differences across children with a type of childhood kidney cancer called Wilms tumour.
In about 30 per cent of children with Wilms tumour, there is an inherited genetic change that increases the risk of developing this cancer. This study, published today (23 January) in Cancer Discovery, ...

WASHINGTON — Researchers have developed a new type of optical memory called a programmable photonic latch that is fast and scalable. This fundamental memory unit enables temporary data storage in optical processing systems, offering a high-speed solution for volatile memory using silicon photonics.
The new integrated photonic latch is modeled after a set-reset latch, a basic memory device used in electronic devices to store a single bit by switching between set (1) and reset (0) states based on inputs.
“While optical communications and computing have seen significant progress over the past decades, data storage has been predominantly implemented using electronic memory,” ...
