Tumor suppressor protein SMAR1 modulates the roughness of cell surface: combined AFM and SEM study (2009)

Kaul-Ghanekar, Ruchika, Singh, Sandeep, Mamgain, Hitesh, Jalota-Badhwar, Archana, Paknikar, Kishore M, Chattopadhyay, Samit

Abstract Background Imaging tools such as scanning electron microscope (SEM) and atomic force microscope (AFM) can be used to produce high-resolution topographic images of biomedical specimens and...

Stabilization of SMAR1 mRNA by PGA2 involves a stem loop structure in the 5' UTR (2007)

Pavithra, Lakshminarasimhan, Rampalli, Shravanti, Sinha, Surajit, Sreenath, Kadreppa, Pestell, Richard G., Chattopadhyay, Samit

Prostaglandins are anticancer agents known to inhibit tumor cell proliferation both in vitro and in vivo by affecting the mRNA stability. Here we report that a MAR-binding protein SMAR1 is a target...

SMAR1 and Cux/CDP modulate chromatin and act as negative regulators of the TCR{beta} enhancer (E{beta}) (2004)

Kaul-Ghanekar, Ruchika, Jalota, Archana, Pavithra, L., Tucker, Philip, Chattopadhyay, Samit

Chromatin modulation at various cis-acting elements is critical for V(D)J recombination during T and B cell development. MARβ, a matrix-associated region (MAR) located upstream of the T cell...

Tumor Suppressor SMAR1 Mediates Cyclin D1 Repression by Recruitment of the SIN3/Histone Deacetylase 1 Complex†

Rampalli, Shravanti, Pavithra, L., Bhatt, Altaf, Kundu, Tapas K., Chattopadhyay, Samit

Matrix attachment region binding proteins have been shown to play an important role in gene regulation by altering chromatin in a stage- and tissue-specific manner. Our previous studies report that...

p53 Target Gene SMAR1 Is Dysregulated in Breast Cancer: Its Role in Cancer Cell Migration and Invasion

Singh, Kamini, Mogare, Devraj, Giridharagopalan, Ramprasad Obula, Gogiraju, Rajinikanth, Pande, Gopal, Chattopadhyay, Samit

Tumor suppressor SMAR1 interacts and stabilizes p53 through phosphorylation at its serine-15 residue. We show that SMAR1 transcription is regulated by p53 through its response element present in the...
