Hydrogen sulphide donors selectively potentiate a green tea polyphenol EGCG-induced apoptosis of multiple myeloma cells

Posted by in category: biotech/medical

Circa 2017 Egcg an active ingredient in green tea kills cancer.


Hydrogen sulphide (H2S) is a colourless gas with the odour of rotten eggs and has recently been recognized as a signal mediator in physiological activities related with the regulation of homeostasis, the vascular system and the inflammatory system. Here we show that H2S donors, including sodium hydrogen sulphide (NaHS), GYY 4137 and diallyltrisulfide (DATS), synergistically enhanced the anti-cancer effect of a green tea polyphenol (−)-epigallocatechin-3-O-gallate (EGCG) against multiple myeloma cells without affecting normal cells. NaHS significantly potentiated the anti-cancer effect of EGCG and prolonged survival in a mouse xenograft model. In this mechanism, H2S enhanced apoptotic cell death through cyclic guanosine monophosphate (cGMP)/acid sphingomyelinase pathway induced by EGCG.

Science competitions can help to catapult your science into the real world

Posted by in categories: biotech/medical, genetics, science

The XPrize and other competitions are helping to advance science and technological innovation.


Over the years, we have had alumni go on to become successful academic scientists, company managers and entrepreneurs. The networks that the participants create with each other during the competition are useful to tap into throughout their careers. Recently, I also learnt that a winning team from 2020 decided to create a bioelectronics start-up, INIA Biosciences, that aims to use ultrasound to interact with the immune system to relieve chronic inflammatory diseases.

More companies and foundations are seeing the advantages of science competitions and are organizing innovation challenges. The organizers benefit from recruiting talented people, gaining fresh ideas and promoting an image of innovativeness. The participants are rewarded with training, network building and prize money. In addition to the Innovation Cup, we also organize events such as the €1 million Future Insight Prize, which is given out annually to honour and enable scientists solving key challenges of humanity.

Newly discovered brain cells may be a memory filing system, study suggests

Posted by in categories: biotech/medical, computing, neuroscience

A scientist opens a laptop in front of a patient. On screen, a boy, tied to a fleet of balloons, fades in. As he rises into the air, the scene cuts abruptly to an office, where a man sits in front of his boss. A question then appears: “Was anyone in the video wearing a tie?”

Jie Zheng, a postdoctoral fellow at Boston Children’s Hospital, had flown to Los Angeles to show the video to this patient, who has a severe seizure disorder. Like with the 18 other patients who were part of the study, neurosurgeons had placed electrodes in the patient’s brain to pinpoint what had been causing their seizures. Zheng and a group of scientists in a federally funded BRAIN Initiative consortium used this opportune moment to find neurons involved in the creation of memories. While subjects watched clips from movies and answered questions that tested their memory of the videos, the electrical activity of their brains was monitored.

Over three years, the work — a collaboration between researchers at Cedars-Sinai in L.A., Boston Children’s, and the University of Toronto — led to the discovery of two new groups of brain cells: boundary and event cells. The researchers theorized that these neurons are involved in cleaving experiences into distinct events that humans can better remember. The study, published in Nature Neuroscience, may pave the way for new treatments for memory disorders, the authors said.

Cellular rejuvenation therapy safely reverses signs of aging in mice

Posted by in categories: biotech/medical, life extension, neuroscience

One group of mice received regular doses of the Yamanaka factors from the time they were 15 months old until 22 months, approximately equivalent to age 50 through 70 in humans. Another group was treated from 12 through 22 months, approximately age 35 to 70 in humans. And a third group was treated for just one month at age 25 months, similar to age 80 in humans.


LA JOLLA—(March 7, 2022) Age may be just a number, but it’s a number that often carries unwanted side effects, from brittle bones and weaker muscles to increased risks of cardiovascular disease and cancer. Now, scientists at the Salk Institute, in collaboration with Genentech, a member of the Roche group, have shown that they can safely and effectively reverse the aging process in middle-aged and elderly mice by partially resetting their cells to more youthful states.

“We are elated that we can use this approach across the life span to slow down aging in normal animals. The technique is both safe and effective in mice,” says Juan Carlos Izpisua Belmonte, co-corresponding author and a professor in Salk’s Gene Expression Laboratory. “In addition to tackling age-related diseases, this approach may provide the biomedical community with a new tool to restore tissue and organismal health by improving cell function and resilience in different disease situations, such as neurodegenerative diseases.”

Drugs pollute rivers, add to resistance crisis

Posted by in categories: biotech/medical, chemistry, health

Drugs are polluting rivers and adding to the resistance crisis as well as affecting riverine ecosystems.


Pharmaceutical pollution in the world’s rivers is threatening environmental and human health and the attainment of UN goals on water quality, with developing countries the worst affected, a global study warns.

Active pharmaceutical ingredients (APIs) could be contributing to antimicrobial resistance in microorganisms, and may have unknown long-term effects on human health, as well as harming aquatic life, according to the report published in Proceedings of the National Academy of Sciences.

In Mice, a Potential New Treatment Eradicates Ovarian And Colorectal Cancer in Days

Posted by in category: biotech/medical

An experimental new type of cancer treatment has yielded some impressive results in mice: the eradication of advanced-stage ovarian and colorectal cancer in the animals as little as six days.

The new therapy has only been tested in mice so far, so let’s not get too excited just yet. However, the early signs are promising, and human clinical trials could be underway by the end of the year.

The treatment involves tiny ‘drug factory’ beads that are implanted into the body and deliver a continuous, high dose of interleukin-2 (IL2) – a natural compound that enlists white blood cells in the fight against cancer.

Single test for over 50 genetic diseases will cut diagnosis from decades to days

Posted by in categories: biotech/medical, genetics

Further research shows that the test is accurate.

When it comes to genetic neurological and neuromuscular diseases, screening early is key to getting the right treatment. A new DNA test developed by researchers at the Garvan Institute of Medical Research in Sydney may help in this process, as reported by the institution in a press release published on Saturday.


Garvan researchers have shown how new genomic sequencing technology can reduce the ‘diagnostic odyssey’ experienced by people with rare neurological and neuromuscular diseases.
