Invasive Ductal Carcinoma of the Breast in a Transgender Man: A Case Report.

There is limited literature about breast cancer in the transgender population. Very little is known about how gender-affirming hormone therapy affects their breast cancer risk. On the other end, for those diagnosed with breast cancer, there are no clinical guidelines to manage their breast cancer, specifically, how to manage their gender-affirming hormone therapy during breast cancer treatment.

Synaptic BMAL1 phosphorylation controls circadian hippocampal plasticity.

The time of day strongly influences adaptive behaviors like long-term memory, but the correlating synaptic and molecular mechanisms remain unclear. The circadian clock comprises a canonical transcription-translation feedback loop (TTFL) strictly dependent on the BMAL1 transcription factor. We report that BMAL1 rhythmically localizes to hippocampal synapses in a manner dependent on its phosphorylation at Ser [pBMAL1(S42)].

Mammalian Target of Rapamycin (mTOR) Pathway Is Critical in Developing Most Renal Cell Tumors.

Objective: Various renal cell carcinomas (RCC) are derived from different segments of the renal tubular origin, which determines their morphological and immunohistochemical phenotype and their molecular signaling pathway as a therapeutic target. Most of these tumors utilize the mammalian target of rapamycin (mTOR) pathway to activate pathways involving metabolic and nutritional supplies.

Methods: Overexpressed mTOR signals are reported in more than 90% of the most common types of RCC.

A Brief History, the Progress in the Variants of Therapies against Metastatic Neoplasms, and the Role of Pathologists.

Chemotherapy originated in the early 1960s. The initial chemotherapeutic agents focused on blocking metabolic pathways and found substantial success in certain types of tumors, but they are generally considered toxic to all normal and tumor cells, and they have significant side effects. As more scientific studies began to identify many new, specific targets and mutations, along with a multitude of growth pathways in tumor cells, new agents targeting cell growth pathways began to emerge in the late 1990s and early 2000s.

Dose-dependent effects of testosterone on spatial learning strategies and brain-derived neurotrophic factor in male rats.

Studies suggest that males outperform females on some spatial tasks. This may be due to the effects of sex steroids on spatial strategy preferences. Past experiments with male rats have demonstrated that low doses of testosterone bias them toward a response strategy, whereas high doses of testosterone bias them toward a place strategy.

Risk Factors for Acute Kidney Injury During High-dose Chemotherapy and Outcomes for Patients With Relapsed Germ Cell Tumors.

Background: Patients with relapsed germ cell tumors (GCTs) can be cured with salvage chemotherapy. We evaluated the risk factors and outcomes of patients who had developed acute kidney injury (AKI) during high-dose chemotherapy (HDCT) for relapsed GCT.

Patients And Methods: All patients were scheduled to receive 2 consecutive courses of HDCT per our standard protocol.

Differences in Baseline Characteristics and White Blood Cell Ratios Between Racial Groups in Patients with Pancreatic Adenocarcinoma.

Purpose: Pancreatic adenocarcinoma remains a malignancy with poor prognosis. Black patients experience poorer overall survival compared with other races. Recent studies have elucidated certain prognostic factors at the time of diagnosis of pancreatic cancer which have largely not been studied for differences between racial groups.

Diagnostic role of kidney injury molecule-1 in renal cell carcinoma.

Despite rapid advances in diagnostic and therapeutic medicine, renal cell carcinoma (RCC) continues to cause significant morbidity and mortality in patients. While there has been a shift towards earlier detection, approximately 16% of patients present with metastatic disease at the time of diagnosis. Kidney injury molecule-1 (KIM-1) is a glycoprotein that has been shown to be a robust and reliable biomarker of acute proximal tubular injury.

Outcomes in Patients With Metastatic Pancreatic Adenocarcinoma With the Introduction of New Chemotherapeutic Drugs: 10-Year Experience of a Single NCI-designated Comprehensive Cancer Center.

Objectives: Adenocarcinoma of the pancreas represents the third leading cause of cancer-related death in the United States. Drug combinations, FOLFIRINOX (5-FU, leucovorin, irinotecan, and oxaliplatin) and gemcitabine/nab-paclitaxel, showed a clinically meaningful benefit when compared with single-agent gemcitabine in phase III trials. The goal of this study was to investigate whether there was an increase in overall survival (OS) for patients treated for metastatic pancreatic cancer after the introduction of the above regimens.

Multiorgan infection: Treatment of an immigrant in the United States.

We discuss the clinical presentation and management of a 36-year-old woman presenting with a 12-year history of recurrent hydatid disease, a disease caused by and other species, which is rarely seen in the contiguous United States. She has had multiple procedures since her diagnosis in 2005 and is still closely being followed for possible disease recurrence.

MicroRNA93 regulates proliferation and differentiation of normal and malignant breast stem cells.

MicroRNAs (miRNAs) play important roles in normal cellular differentiation and oncogenesis. microRNA93 (mir-93), a member of the mir106b-25 cluster, located in intron 13 of the MCM7 gene, although frequently overexpressed in human malignancies may also function as a tumor suppressor gene. Using a series of breast cancer cell lines representing different stages of differentiation and mouse xenograft models, we demonstrate that mir-93 modulates the fate of breast cancer stem cells (BCSCs) by regulating their proliferation and differentiation states.
