The immune checkpoint proteins, Programmed Death Receptor 1 (PD-1) and Programmed Death Ligand -1 (PD-L1), are crucial for maintaining fetomaternal immune tolerance and immune escape in cancers. In this study, we performed a comprehensive immunohistochemical study of PD-L1 expression in a large cohort of trophoblastic tissues and tumors. We found that normal villi and hydatidiform moles showed a heterogeneous PD-L1 staining among trophoblast (strong in syncytiotrophoblast, moderate in intermediate trophoblast, and weak/negative in cytotrophoblast).

Versican is a proteoglycan known to interact with cells to influence their ability to proliferate, differentiate, migrate, invade and assemble extracellular matrix, with all of these cell functions present during placentation. In the placenta, cytotrophoblast cells have the ability to differentiate into the syncytiotrophoblast, a mechanism that is greatly increased in gestational trophoblastic diseases (GTD). Nevertheless, the molecular signaling underlying the increased syncytiotrophoblast differentiation are still being unveiled and may result in novel therapeutic targets for GTD. Read More

Introduction: Leukemia inhibitory factor (LIF) and insulin like growth factor-1 (IGF-1) are two of the most important growth factors mediating trophoblast actions. We hypothesized that the localization and expression patterns of LIF and IGF-1 in partial and complete hydatidiform moles (HM) compared with normal first trimester placentas may provide an understanding of the proliferative processes in HMs.
Methods: The study population included curettage material of women diagnosed as complete or partial HM as a result of histopathological and immunohistochemical examination (complete HM group, n = 8; partial HM group, n = 8) and women undergoing dilatation&curettage for unwanted pregnancies (control group, n = 8).

The trophoblast cells which form the placenta, have a high potential for invading other tissues. Owing to certain mechanisms, trophoblast cells may lose their ability to control cell proliferation, and develop into pregnancy-related tumors, known as choriocarcinomas. Choriocarcinomas mostly develop from the hydatidiform mole, which is frequently found in pregnant women. Read More

Background: The hallmark of gestational trophoblastic disease is the production of human chorionic gonadotropin (hCG) due to the hyperproliferation of extraembryonic trophoblast cells. Previous studies show hCG has thyrotropic action due to its structural similarity with thyroid stimulating hormone (TSH) molecules. Germ cell tumors represent 15-20% of all ovarian tumors and can be malignant or benign. Read More

Benign hydatidiform mole, complete or partial, is the most common type of gestational trophoblastic disease (GTD) characterised by excessive trophoblastic proliferation and abnormal embryonic development. Although most complete hydatidiform moles (CHMs) are diploid androgenetic, a few cases of CHMs are biparental, characterised by recurrence and familial clustering. In these rare cases, mutations in NLRP7 or KHDC3L genes, associated with maternal imprinting defects, have been implicated. Read More

Recurrent hydatidiform moles (RHM) are aberrant human pregnancies characterized by absence of, or abnormal, embryonic development, hydropic degeneration of chorionic villi, and hyperproliferation of the trophoblast. Biallelic mutations in two maternal-effect genes, NLRP7 and KHDC3L, underlie the causation of RHM in 60% of patients. We performed exome sequencing on a patient with six pregnancy losses, two miscarriages and four HM, and found no variants that affect the functions of the known genes. Read More
