The interaction between RNA-binding proteins (RBPs) and circular RNAs (circRNAs) has emerged as a key area of interest in understanding cancer biology. As critical regulators of gene expression, RBPs control the formation and function of circRNAs, influencing various cancer-related processes such as tumor proliferation, metastasis, drug resistance, and immune evasion. This dynamic interplay has positioned the circRNA-RBP network as a promising target for developing innovative cancer therapies.
A Simon Fraser University new study is challenging a commonly held misconception that there’s little organizations can do to encourage employees to disclose mental health concerns. World Health Organization data shows 15 per cent of adults have a mental health concern, while other surveys have found 65 per cent of employees believe mental health concerns interfere with their job. Yet many organizations, even those with mental health supports and programs, see disclosure as a personal decision they have no influence over.
“That’s just not what we saw in the data,” says Zhanna Lyubykh, assistant professor at Beedie School of Business and lead author of the study published in Human Resource Management. “Organizations can do a lot to help employees disclose. Much of it comes down to employee perceptions of how disclosure is going to be handled, which is absolutely within an organization’s control.”
A series of preclinical studies show that a new compound, SHP1705, targets circadian clock proteins hijacked by glioblastoma stem cells, impairing the cancer cells’ ability to survive and grow. SHP1705 is also the first clock-targeting compound to complete a phase 1 clinical trial, where it was found to be safe and well-tolerated in humans. Glioblastoma is the most common cancerous brain tumor in adults—and one of the most difficult to treat. Most patients receive a combination of surgery, radiation and chemotherapy, but tumors typically return and resist further treatment. Circadian clock proteins, which regulate the body’s sleep-wake cycle and other daily rhythms at the cellular level, offer a potential solution. Glioblastoma cells hijack these proteins in order to replicate, so switching them off could slow or halt tumor growth. Through a series of biochemical, cellular and animal studies, the researchers tested SHP1705’s ability to neutralize glioblastoma stem cells, finding it to be highly effective. A phase 1 clinical trial led by Synchronicity Pharma, a biotechnology startup that Kay co-founded, showed that SHP1705 was well-tolerated in humans.
