Science Roundup – June 7, 2014

Starting with today’s edition, Sciberomics will present a weekly roundup of science research from around the globe.

ASCO Annual Meeting

This past week was super-busy – science-wise, with the NIH grant deadline, many significant papers being published, and the American Society of Clinical Oncology (ASCO) annual meeting in Chicago, IL. The fun of having to work on an NIH grant notwithstanding, my experience at ASCO makes me say that it was indeed an awesome meeting. Scientists and clinicians presented some very exciting research. To list all the important studies presented at ASCO would make this post a #longread. But here I am listing only a few of the many important clinical research studies that featured at this meeting:

Adjuvant Ipilimumab Significantly Improves Recurrence-Free Survival in Patients With High-Risk Stage III Melanoma

PD-1–Targeting Antibody Pembrolizumab Produces Long-Term Responses in Patients With Metastatic Melanoma

Cediranib Plus Olaparib Significantly Increases Progression-Free Survival in Women With Recurrent Ovarian Cancer

Chemotherapy Plus Either Bevacizumab or Cetuximab Results in Similar Survival Benefits in Metastatic Colorectal Cancer

There were several other notable developments in the research world of biology and medicine this week.

Increasing analyses of microbes from different locations in the human body has helped us understand the importance of the human microbiome. Now a study published in this week’s Nature (June 4, 2014) shows how early childhood malnutrition affects the maturation of gut microbes. Moreover, even after correcting this early malnutrition with diet, gut microbes do not sufficiently recover from the early insult and may require additional intervention.

A study published in Science (June 6, 2014) presents an innovative computational model that predicts when embryonic stem cells will self-renew or differentiate in culture. This model identifies, with high accuracy, a small number of transcription factors that can drive the stem cells either to pluripotency or to differentiation.

A new development in stem cell biology may signal a major advance for regenerative medicine. Scientists at Harvard show that by using Laser, they can stimulate human dental stem cells to differentiate and produce tissue regeneration. This research has implications for regenerative medicine for a variety of clinical applications.

The world of 3-D printing is witnessing exciting advances. Now to add to this excitement, scientists in Boston have been able to create synthetic blood vessels using 3-D printing. All the possible applications that this development can result in, makes it very noteworthy.

If you are planning for that late-night movie or an all-night work session, think again. It is very important to get a good night’s sleep or you risk developing Alzheimer’s disease. The findings of a recent randomized clinical trial published in JAMA Neurology show that sleep deprivation increases levels of the protein beta-amyloid, which in turn increases the risk of Alzheimer’s.

With the increasing use of computers, tablets and smartphones, handwriting is becoming a lost art. But now scientists and psychologists have research that shows how handwriting is important for brain development in kids and for increased understanding. “New evidence suggests that the links between handwriting and broader educational development run deep.”

Genomics being the new kid on the block, sequencing technology takes center stage today. Seeking to further expand its reach in molecular diagnostics to sequencing, Swiss pharmaceutical giant Roche acquired Genia Technologies Inc. DNA sequencing firm.

In the research world of today, collaborations, mergers, and acquisitions have become the key to success and survival. As a testament to this, we are witnessing a number of collaborations among different groups.

  1. Sysmex Inostics is collaborating with Merck to develop and commercialize a biomarker test (RAS kit) for patients with metastatic colorectal cancer.
  2. NanoString and Celgene are collaborating to develop a companion diagnostic to support the clinical validation of the drug lenalidomide (REVLIMID) used for the treatment of diffuse large B-cell lymphoma (DLBCL).
  3. AstraZeneca’s MedImmune is developing a novel immune therapy for patients with non-small cell lung cancer (anti-PD-L1 therapy – MEDI4736). Now Roche’s Ventana has established collaboration with MedImmune to develop a companion diagnostic for this drug MEDI4736 that is currently in clinical studies.
