An estimated 14,000 pseudogenes, or defective copies of genes, may fall into that category, albeit with some exceptions. Recent studies, however, have cast a new spotlight on a menagerie of other molecules, including some with a lineage far older than the human species, that may play significant roles in the development and progression of cancer and other diseases.&lt;/p&gt;&lt;p&gt;Martin Taylor, MD, PhD, assistant professor of pathology and laboratory medicine at the Brown University Center on the Biology of Aging and the Legorreta Cancer Center in Providence, Rhode Island, began studying one kind of genomic dark matter, LINE-1 retrotransposons, approximately 15 years ago. “The overwhelming evidence says that these are just parasitic sequences that we’ve been evolving with for billions of years,” he says of the mobile elements. “They’re actually older than multicellular organisms.” The virus-like, self-copying sequences, in fact, may have given rise to viruses.&lt;/p&gt;&lt;p&gt;Astoundingly, LINE-1 has effectively written at least one-third of the human genome through its copy-and-paste mechanism. Most of its own 500,000 copies are “fossils” from when humans mutated and defeated the once full-length retrotransposons. However, an estimated 6000 elements are more or less still intact; of those, maybe 100–150 are still functional and capable of hopping around and inserting themselves into other sequences, Dr Taylor says. They are repressed in healthy tissues but can become activated in the event of diseases such as cancer and autoimmune diseases.&lt;/p&gt;&lt;p&gt;By sequencing cancers, researchers have found that LINE-1, on rare occasion, can insert itself into a tumor suppressor gene such as APC or P10 and promote cancer. Work by Dr Taylor and others suggests that LINE-1 also may contribute to cancer in other ways. Those cancer-abetting mechanisms, he says, “have to do with the fact that when LINE-1 gets turned on, the cell thinks it’s infected with a virus—or at least has a virus-like response—and that causes inflammation.” The defensive response, research suggests, can manipulate the tumor microenvironment and alter cell signaling pathways to promote carcinogenesis.&lt;/p&gt;&lt;p&gt;In addition, Dr Taylor says, “The transposons cause a huge amount of DNA damage, and the thinking in the field now is that they may contribute to the chromosomal instability that we see as a hallmark of cancer.” He sees LINE-1 not as a classic cancer driver but rather as an accelerator that more broadly contributes to cancer development and progression, thoug","PeriodicalId":9410,"journal":{"name":"Cancer Cytopathology","volume":"132 11","pages":"671-672"},"PeriodicalIF":2.6,"publicationDate":"2024-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cncy.22917","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142564078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The frequency of positive PWC results and cytologic features was assessed, and correlations between positive PWC results and clinicopathologic factors were examined, including prognosis, in the GAS group.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Positive PWC results were significantly more frequent in patients who had GAS at 24% (15 of 62 patients) compared with 7% (seven of 100 patients) in those who had usual-type endocervical adenocarcinoma. The cytologic features of GAS included distinct cellular atypia (enlarged nuclei, nuclear irregularity) and frequent formation of spherical clusters (10 of 15 cases) without the golden-yellowish mucus commonly seen in cervical smears. A positive PWC result in GAS was significantly correlated with larger tumor size, parametrium invasion, lymph node metastasis, and elevated carbohydrate antigen 19-9 levels. In patients with stage I GAS, the PWC-positive group had significantly shorter disease-free survival and overall survival compared with the PWC-negative group.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Positive PWC findings are frequent in cervical GAS and are associated with pathologic factors indicative of tumor growth and progression. In patients who have stage I GAS, positive PWC results may indicate a poor prognosis, warranting further investigation.</p>\u0000 </section>\u0000 </div>","PeriodicalId":9410,"journal":{"name":"Cancer Cytopathology","volume":"133 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142388278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
