23andMe Has a New Genetic Cancer Test. But the Results Don ’t Tell You the Whole Story

Consumer genetics company 23andMe is diving deeper into the medical space. On Jan. 22, the company announced that the Food and Drug Administration (FDA) approved its newest report, which can flag whether people have genetic variants that may raise their risk of developing colorectal cancer. The new test looks for two gene variants associated with MUTYH-associated polyposis, an inherited colorectal cancer syndrome. “If left unchecked, carrying both of these variants or having two copies of one increases the risk of developing colorectal cancer to between 43 and 100 percent,” according to 23andMe. The test will be available as part of 23andMe’s Health and Ancestry spit test (which costs $199), but as with many of the company’s more sensitive reports, users must opt in to receive their results. “For people who get that two-variant result, this can be absolutely life-saving,” says Jamaica Perry, senior product scientist at 23andMe. “Colorectal cancer is something that can get pretty far along before somebody might notice symptoms of it. If somebody finds out in their 20s or 30s that they have this increased risk, that could actually help them set up a surveillance plan with their doctor and give them a much better life.” But a simple genetic test doesn’t tell the whole story. The vast majority of colorectal cancers aren’t caused by known genetic factors, so a person who doesn’t test positive for these variants may...

Authors: Pennisi PA, Fernández MC, Martin A Abstract Pheochromocytomas/paragangliomas (PCCs/PGLs) are rare neuroendocrine tumors, developed from chromaffin cells derived from the neural crest. From a genetic point of view PCCs/PGLs are divided as sporadic cases, and inherited cases as part of hereditary (familial) syndromes. While the majority is benign, up to 26% of PCCs/PGLs will undergo malignant transformation. Validated prognostic pathological parameters for malignant PCCs/PGLs are still lacking. Signaling that follows the interactions between IGFs and their receptor/s in tumor cells received extensive ...

Authors: Silva MAFS, Dechichi P, Limirio PHJO Abstract Childhood obesity is a considerable worldwide health problem and a major risk factor for several chronic diseases. Fat rich diets result in altered serum levels of lipids, cytokines and hormonal factors, which influence skeletal acquisition and promote microstructural and mechanical behavior changes in bone, especially to bone quality and quantity. However, the possible longterm implications of high-fat diets in childhood are controversial. Despite not fully understood, multiple signaling pathways which support bone tissue homeostasis are altered under hyperlip...

Authors: Henry RK Abstract Glucose dysregulation (GD), a feature of growth hormone excess, in the setting of acromegaly is well known by clinicians. However, less well known is that GD may be a feature of growth hormone deficiency. The fact that either ends of the spectrum of growth hormone (excess or deficiency) can be associated with diabetes mellitus is unique and clinicians should especially recognize that impaired glucose tolerance and even diabetes mellitus may develop in individuals predisposed to having growth hormone deficiency.

Conclusions: There were significant differences with respect to clinical characteristics and comorbidity prevalence according to metformin use among Korean type 2 diabetes patients. Long-term follow-up of these patients is necessary to observe how this difference will affect clinical outcomes for these patients. PMID: 32774367 [PubMed]

Authors: Plunk EC, Richards SM Abstract The epigenome of an individual can be altered by endogenous hormones, environment, age, diet, and exposure to endocrine disrupting chemicals (EDCs), and the effects of these modifications can be seen across generations. Epigenetic modifications to the genome can alter the phenotype of the individual without altering the DNA sequence itself. Epigenetic modifications include DNA methylation, histone modification, and aberrant microRNA (miRNA) expression; they begin during germ cell development and embryogenesis and continue until death. Hormone modulation occurs during the agei...

Authors: Antinozzi C, Sgrò P, Di Luigi L Abstract Among metabolic diseases, carbohydrate metabolism disorders are the most widespread. The most common glucose pathological conditions are acquired and may increase the risk of type 2 diabetes, obesity, heart diseases, stroke, and kidney insufficiency. Phosphodiesterase type 5 inhibitors (PDE5i) have long been used as an effective therapeutic option for the treatment of erectile dysfunction (ED). Different studies have demonstrated that PDE5i, by sensitizing insulin target tissues to insulin, play an important role in controlling the action of insulin and gluco...

Authors: Hu B, Zhao M, Luo D, Yu C, Shao S, Zhao L, Yang Y, Zhang X, Zhao J, Gao L Abstract Hypothyroidism is a common disease, and its molecular mechanism still needs further investigation. Lysine succinylation is found to be involved in various metabolic processes associated with hypothyroidism. We performed quantitative analysis on lysine succinylome in thyroids of rats with hypothyroxinemia, which was induced through the administration of a high-fat diet. Overall, 129 differentially expressed proteins were quantified. Downregulated proteins were enriched in the thyroid hormone synthesis and thyroid hormone sign...

Conclusion: Our cumulative results suggested that hyperoside inhibits the proliferation of SV40-MES13 cells through the suppression of the ERK/CREB/miRNA-34a signaling pathway, which provides new insight to the current investigation on therapeutic strategies for diabetic nephropathy.
