Why we write about this topic:<\/summary>

As per the World Health Organization, in 2020 7.8 million alive women were diagnosed with breast cancer in the previous five years, making it the world’s most prevalent cancer. <\/p><\/div><\/details>\n\n\n\n

Researchers at the University of Basel and the University Hospital Basel have tested the possibility of artificially maturing (or more precisely, differentiating) breast cancer cells as an approach to turn them into a more normal type of cell, writes the university in a press release<\/a>.<\/p>\n\n\n\n

Differentiation is a therapeutic strategy that has been successfully implemented in treating blood-borne cancers but not yet in solid tumors. In the journal Oncogene<\/em>, a research group led by Professor Mohamed Bentires-Alj now reports promising new results. The researchers were able to use differentiation to treat an especially aggressive type of carcinoma called triple-negative breast cancer.<\/p>\n\n\n\n

\u201cWe show here that we can convert breast cancer cells to less harmful cells that stop growing,\u201d says Bentires-Alj who is a group leader at the Department of Biomedicine.<\/p>\n\n\n\n

The dual activity of the estrogen receptor<\/h2>\n\n\n\n

The hormone estrogen acts as a signaling molecule in cells by binding to its cognate receptor, the estrogen receptor, thereby inducing a range of biological effects. In the normal breast, cells that express the estrogen receptor are mature specialized breast cells and do not proliferate.<\/p>\n\n\n\n

In contrast, in a fraction of breast cancers cells that express the estrogen receptor proliferate significantly. These breast cancers are called estrogen receptor-positive breast cancers and comprise about 75 percent of all breast cancer cases. Because they are susceptible to estrogen, they can be treated with anti-estrogenic therapies, which are highly effective in patients.<\/p>\n\n\n\n

The triple-negative breast cancer subtype however, is not susceptible to estrogens or anti-estrogens. This type of carcinoma occurs mainly in pre-menopausal women and often lacks effective treatment options. \u201cOur initial idea was to induce estrogen receptor expression in order to convert triple-negative breast cancer into estrogen-receptor positive breast cancer because of more effective treatment options available for this subtype,\u201d says the study\u2019s lead author Dr. Milica Vulin.<\/p>\n\n\n

CC Diagnostics on its way to European certification with new cervical cancer test<\/div>
Things are going well for CC Diagnostics. The start-up from the Dutch city of Groningen is developing a new test for cervical cancer that works more efficiently and should be more user-friendly for female recipients. <\/div><\/div><\/div>\n\n\n

Implications for treatment<\/h2>\n\n\n\n

\u201cUnderstanding the cellular and molecular mechanisms that define cancer and how these mechanisms differ from normal cells is crucial for developing new innovative therapies,\u201d says Bentires-Alj. The results open a new avenue for treating triple-negative breast cancer. \u201cThe compounds used in this study are already in clinical trials to treat other cancer types, including blood-borne, lung, and pancreatic cancer,\u201d the researcher continues. This underlines the possibility of testing these compounds in clinics and in treating breast cancer.<\/p>\n\n\n\n

Especially in the era of immunotherapies, it has been suggested that \u201cnormal-like\u201d cells can be cleared by the immune system while \u201ccancerous\u201d cells evade killing by immune cells. In the future, it remains to be determined if differentiation therapy can be combined with immunotherapies. \u201cWe are pursuing such strategies, and only time and resources are in our way to make further progress,\u201d the researchers conclude.<\/p>\n","protected":false},"author":2084,"featured_media":515140,"template":"","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[34665],"tags":[128601,128604,32322],"location":[52892],"internal_archives":[],"class_list":["post-407355","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-health","tag-breast-cancer-5","tag-university-hospital-basel","tag-university-of-basel","location-switzerland"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2022\/09\/Methica_CC_prototype-scaled.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/mauro-mereu\/","display_name":"Mauro Mereu"},"relative_dates":{"created":"Posted 4 years ago","modified":"Updated 4 years ago"},"absolute_dates":{"created":"Posted on September 21, 2022","modified":"Updated on September 21, 2022"},"absolute_dates_time":{"created":"Posted on September 21, 2022 9:35 am","modified":"Updated on September 21, 2022 9:35 am"},"featured_img_caption":"","tax_additional":{"category":{"linked":["Health<\/a>"],"unlinked":["Health<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["breast cancer<\/a>","University Hospital Basel<\/a>","University of Basel<\/a>"],"unlinked":["breast cancer<\/span>","University Hospital Basel<\/span>","University of Basel<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":["pll_632abe8036311<\/a>"],"unlinked":["pll_632abe8036311<\/span>"],"slug":"post_translations","name":""},"location":{"linked":["Switzerland<\/a>"],"unlinked":["Switzerland<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/407355","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2084"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/515140"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=407355"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=407355"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=407355"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=407355"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=407355"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
