African Americans With p16+ and p16- Oropharyngeal Squamous Cell Carcinomas Have Distinctly Poor Treatment Outcomes Independent of Medical Care Access.

JCO Oncol Pract 2021 May;17(5):e695-e702

Department of Otolaryngology-Head and Neck Surgery, University Hospitals Cleveland Medical Center, Case Western Reserve University School of Medicine, Cleveland, OH.

Purpose: Human papilloma virus-positive (HPV+) oropharyngeal squamous cell carcinoma (OPSCC), diagnosed with p16 immunohistochemistry, is associated with favorable prognosis; however, this connection was established using European American (EA)-skewed populations. The impact of p16/human papillomavirus status on outcomes in African American (AA) OPSCC patients remains to be settled. In this study, we determine the association between cancer disparity and p16 status in an OPSCC cohort controlling for time to treatment initiation (TTI), a surrogate for medical care access.

Risk of precancerous cervical lesions in women using a hormone-containing intrauterine device and other contraceptives: a register-based cohort study from Denmark.

Hum Reprod 2021 May 11. Epub 2021 May 11.

Department of Obstetrics and Gynecology, Randers Regional Hospital, Randers, Denmark.

Study Question: Is the risk of high-grade precancerous cervical lesions and/or is the risk of lesion progression increased in users of a hormone-containing intrauterine device (HIUD) compared with users of other contraceptive methods.

Summary Answer: Women starting use of HIUD had the same subsequent risk of cervical intraepithelial neoplasia 3+ (CIN3+) as copper IUD (CIUD) users, and both groups tended to have lower risks than oral contraceptives (OC) users.

What Is Known Already: HIUDs may cause inflammatory and immunosuppressive changes that may potentially affect the risk of persistent human papillomavirus infection and precancerous cervical lesions. Read More

A Ran-binding protein facilitates nuclear import of human papillomavirus type 16.

PLoS Pathog 2021 May 11;17(5):e1009580. Epub 2021 May 11.

Institute of Cellular Virology, Westphalian Wilhelms-University of Münster, Münster, Germany.

Human papillomaviruses (HPVs) utilize an atypical mode of nuclear import during cell entry. Residing in the Golgi apparatus until mitosis onset, a subviral complex composed of the minor capsid protein L2 and viral DNA (L2/vDNA) is imported into the nucleus after nuclear envelope breakdown by associating with mitotic chromatin. In this complex, L2 plays a crucial role in the interactions with cellular factors that enable delivery and ultimately tethering of the viral genome to mitotic chromatin. Read More

LxCxD motif of the APC/C coactivator subunit FZR1 is critical for interaction with the retinoblastoma protein.

Exp Cell Res 2021 May 7:112632. Epub 2021 May 7.

School of Biotechnology, Jawaharlal Nehru University, New Delhi-110067, India. Electronic address:

Retinoblastoma protein (pRB) regulates cell cycle by utilizing different regions of its pocket domain for interacting with E2F family of transcription factors and with cellular and viral proteins containing an LxCxE motif. The LxCxE motif is present on FZR1, an adaptor protein of the multi-subunit E3 ligase complex anaphase-promoting complex/cyclosome (APC/C). The APC/C complex regulates the timely degradation of multiple cell cycle proteins for mitotic exit and maintains G1 state. Read More

Pseudoangiosarcomatous squamous cell carcinoma: first case report on penis.

Transl Androl Urol 2021 Apr;10(4):1803-1806

Laboratory Immunofluorescence and Electron Microscopy, University Hospital Universitário Presidente Dutra, São Luís, MA, Brazil.

Pseudoangiosarcomatous squamous cell carcinoma, also called pseudovascular, pseudoangiomatoid or adenoid pseudovascular carcinoma, is an uncommon and highly aggressive variant of squamous cell carcinoma. Histologically, it is characterized by proliferation of atypical keratinocytes with acantholysis and formation of pseudovascular spaces, forming anastomosed channels lined with neoplastic cells that invade the dermis. These cells are positive for cytokeratin and negative for vascular markers such as CD31 and CD34. Read More

J Virol Methods 2021 May 6:114180. Epub 2021 May 6.

Infections and Cancer Biology Group, International Agency for Research on Cancer, Lyon, France. Electronic address:

Background: The MinION sequencer belongs to the third generation of sequencing technology that allows for the generation of ultra-long reads, representing a potentially more effective approach to characterize entire viral genome sequences than other time-consuming and low-throughput methodologies.

Methods: We report the use of the MinION nanopore sequencer to sequence the full-length genome of human papillomavirus (HPV)-ICB2 (7441 bp), which was previously characterized in our laboratory. Three independent MinION libraries were prepared and sequenced using either three consecutive 12 -h runs (Protocol A) or a single run of 48 hours starting from a pool of three barcoded DNA libraries (Protocol B).

Hematopoietic Cell Transplantation and Outcomes Related to Human Papillomavirus Disease in GATA2 Deficiency.

Transplant Cell Ther 2021 May 3;27(5):435.e1-435.e11. Epub 2021 Jan 3.

Immune Deficiency-Cellular Therapy Program, National Cancer Institute, National Institutes of Health, Bethesda, Maryland.

GATA2 deficiency is a bone marrow failure syndrome effectively treated with hematopoietic cell transplantation (HCT), which also addresses the predisposition to many infections (prominently mycobacterial). However, many GATA2-deficient persons who come to HCT also have prevalent and refractory human papilloma virus disease (HPVD), which can be a precursor to cancer. We analyzed 75 HCT recipients for the presence of HPVD to identify patient characteristics and transplantation results that influence HPVD outcomes. Read More
