≤ Cyclin D1 protein affecting global women's health by regulating HPV mediated adenocarcinoma of the uterine cervix.

Adenocarcinoma (ADC) of the uterine cervix (UC) is a rare form of cervical cancer (CC) caused due to the infection of Human Papilloma Virus (HPV). Cyclin D1 is one of the downstream targets of aberrantly activated Notch signaling, contribute to the etiology of CC. However, little is known about the role of Cyclin D1 in the modulation of cervical ADC and is controversial.

Association of pro- and anti-inflammatory cytokines in preeclampsia.

Introduction: The pro- and anti-inflammatory cytokines play crucial role in the development and functions of placenta. Any changes in these cytokines may be associated with many pregnancy-related disorders like preeclampsia. Therefore, the present study is aimed to study the expression of pro-inflammatory (TNF-α, IL-6) and anti-inflammatory (IL-4, IL-10) cytokines in placenta and serum of preeclamptic pregnant women.

HES1 Protein Modulates Human Papillomavirus-Mediated Carcinoma of the Uterine Cervix.

Purpose: Cervical cancer (CC) is the most common cancer affecting women worldwide. Human papillomavirus (HPV) infection is a major contributing factor for the development of CC. The development of CC occurs progressively from precancer stages to cancerous stages (ie, invasive squamous cell carcinoma [ISCC] and adenocarcinoma [ADC]).

Jagged-1 induced molecular alterations in HPV associated invasive squamous cell and adenocarcinoma of the human uterine cervix.

The majority of cervical cancer (CC) cases are attributable to HPV infection. Altered Notch pathway signals and HPV are believed to modify clinicopathogenesis of CC, however, the involvement of each molecular player and its mechanism is still not known. Jagged-1 (JAG1) is one of the ligands that induce Notch pathway.
